Earth Our Home Too : 25 Intelligent Animals

Though we found them in a top 25 listing, we have removed the rating as it is better in this way. They are more intelligent than the other in some way or the other 🙂 Hope we humans do not ruin their home. Earth!

Well here the scale of intelligence is Human’s perspective, we define intelligence here as what according to human brains and ideas conceives, well maybe in Animals’ perspectives we humans may be the dumbest creatures to ruin our own habitat irreversible and moron-species 🙂

We may top their list of Dumbest Species 😛

 

Squids

Squids

Squids are said to be among the brainiest invertebrates in the world. Their brain structure is different from other invertebrates in the ocean, as they share complex features similar to the human brain. Like human beings, squids can be very curious about their environment. They have the ability to learn new skills and develop the capacity to use tools that can either help them repress their boredom and protect them from harm.

Spiders

Spiders

Spiders are among the smallest creatures to possess a proportionately high level of  intelligence. Especially the White-Mustached Portia spiders. These spiders dwell African; Asian; and Australian forests and have demonstrated special learning skills.

Ants

Ants

Though they are small, they have the ability to creatively withstand calamities that would that would wipe another species. Ants are often seen coordinating in massive groups to build nests and hunt for food; and they accommodate to their environment very well. All notable points when it comes to measuring intelligence.

Baboons

Baboons

Baboons are old world monkeys who have cognitive abilities very similar to chimpanzees and orangutans. In terms of the way they behave, one can see how these creatures resemble people. Unlike other animals, studies show that at some level baboons know how to identify stress and cope with it. They create extremely complex social systems and can think critically when confronted with difficult situations.

Sea Lions

Sea Lions

Studies have shown that sea lions possess the ability to think logically and can actually deduce if a=b and b=c, then a=c.

Orangutans

Orangutans

Just chimpanzees, the intelligence of orangutans is reflected in the way they imitate human actions. They also have the unique ability to learn complicated new skills, such as sawing wood or using a hammer and nail to put things together. Orangutans have the ability to understand their surroundings in a more abstract way than other animals so they know how to acclimate to some very harsh environments.

Pigeons

Pigeons

There’s a reason why pigeons have been used numerous times throughout history in places like battle fields . They are extremely good at Geo location and studies have shown that they have an amazing ability to remember people and places throughout the course of their life.

Crows

Crows

Along with pigeons, crows are among the most intelligent birds in the world. They have the ability to solve complicated problems and adapt to tough situations which can easily be seen in the way they gather their food and collect resources.

Sheep

Sheep

Of all the animals, sheep are believed to possess the most powerful memories with some research showing them to be better than humans in certain situations. For example, they have the ability to identify when a fellow sheep is lost in their flock.  Moreover, they exhibit a wide range of emotions and response to various things going on around them which also shows a high level of intelligence.

Raccoons

Raccoons

Known for being resourceful; raccoons are capable of forming complex social relationships and also make use of complex tools when problem solving.

Horses

Horses

Horses have always held a special meaning to humans, apart from the fact that they are very rideable and get us places they are also teachable, have good memories, and are able to respond to complicated commands quickly under stress.

Rhesus Monkeys

Monkeys

Known for having displayed suicidal tendencies and well planned attacks in a group; it’s safe to say that Rhesus Monkeys are extremely smart and resourceful.

Falcons

Falcons

Extremely adept hunters falcons have always been used in the same way as pigeons, to convey messages and do reconnaissance.  Their ability to follow commands and remember territory is formidable.

Rats

rats

Once could easily underestimate the mental capacity of a rat. While they can be revolting sewer dwellers that Hollywood has made them out to be, they are also quite smart. They have very good long term memories and are excellent when it comes to adapting to changing situations.

Owls

Owls

Even during the time of the ancient Greeks, owls were already seen as intelligent animals. While this may appear to be true due to preconceived notions about their “wisdom” this is the “burst your bubble” list item. That’s right, they are actually not that smart compared to other birds.  Technically they shouldn’t even be on this list but how else would we shatter everything you thought you knew?

Cats

Cats

Those who have cats as pets know that these animals are skilled at hunting. They are agile and they possess incredible sensory abilities and though they’re not nearly as trainable as dogs, they are extremely adept at learning new skills.

Squirrels

Squirrels

Squirrels may be small, but their brains should not underrated. Yes, we know what your thinking; every time you almost hit one with your car is because they can’t seem to figure out how to get out of your way, how can they be smart? Well, their intelligence is very focused on one thing; gathering food.  When it comes to storing provisions their minds are uniquely adapted with everything they need which includes a ridiculous memory to remember where they store it.

Elephants

Elephants

Compared to other animals, elephants have larger brains.  Of course just because your brain is big doesn’t necessarily mean much. What matters is the proportion of body mass to brain mass but even with that said elephants are really, really smart by non human standards. These animals use their brains to create and process complex social interactions and seem to even model things such as empathy.

Octopus

Octopuses

When it comes to  group of invertebrates, octopuses are known as the most intelligent. They are highly skilled hunters who use well developed strategies when finding food. And just like most of the other animals on this list they have shown the ability to solve some very complicated problems.

Dogs

Dogs

Although intelligence levels vary across breeds, in general they learn new skills easily and are quick to respond to human training.  Most breeds of dogs like Labrador Retrievers, Border Collies and Poodles aver very curious about their environment and can even notice a change in the smallest detail. Is what appears to be their high emotional intelligence however, that has probably led them to be man’s best friend.

Whales

Whales

Known for their massive size but not often their massive intellect whales often use complex sounds to communicate with each other and coordinate their activities among the group very effectively.  They are also formidable problem solvers.

Parrots

parrots

Although their famous ability to talk is pure mimicry as most people know parrots have excellent memories and like many others on this list are capable of solving relatively complex problems.

Bottlenose Dolphins

Bottlenose Dolphins

When it comes to  body mass to brain ratio, it is a scientific fact that Bottlenose dolphins have among the largest brains in the animal kingdom. Characterized by their advanced communication skills, they have also been considered to be self aware with the ability to recognize themselves in a mirror.

Pigs

ppigs

According to research, a middle aged pig can be as smart as a three year old human being and they know how to adapt to complex environmental situations because they have the ability to learn new skills easily.

Chimpanzees

Chimpanzees

Aside from the fact that chimpanzees look like humans, these animals also have the capacity in some ways to think like humans. They can manipulate their environment and utilize tools in order to help the community accomplish certain tasks.  By and large they are often considered to be the smartest primate and therefore one of the smartest animals in the world.

Earth our Home too : Mimic Octopus

Many creatures seem to have magical abilities, and the mimic octopus is no exception. In the blink of an eye this creature can go from looking like an average octopus to looking like a flat fish, or a sea snake. Watch the video to see the fascinating transformations! – Global Animal

Family name: Octopodidae

Order name: Octopoda
Common name: Mimic octopus
Scientific name: Thaumoctopus mimicus

There are many creatures in the sea that divers long to have encounters with and one’s own personal list can change with experience. Once sharks, turtles, manta rays and other obvious marine wonders have been experienced then each person develops their own personal goals. One creature that is high on many experienced divers wish list is the incredible mimic octopus.

Is this creature really as ‘talented’ as we are told? Are mimics hugely intelligent aquatic chameleons or humble invertebrates just going about their business? Is it the observers who are attributing skills to them that in fact they don’t possess?

Let’s see if we can uncover some truths about the fascinating creature that is the mimic octopus …

Distinguishing Features

Mimics are normally quite small, growing only up to 60 cm (2 feet) long and have a body covered with brown and white stripes or spots, although in a resting state their body colour is more of a pale brown or beige. Their tentacles are around 25 cm in length and no more than pencil thick.

As with all octopus, the mimic has 8 arms, a mantle containing 3 hearts and other internal organs, and a siphon used for jet propulsion. The arms have 2 rows of suckers, each sucker having a touch sensor and a chemoreceptor, allowing the mimic effectively to feel and taste its food before it eats it. It has a large brain but lacks the sense of hearing.

Like all octopus the mimic has pigment sacs on the skin called chromatophores which can be contracted or expanded to produce rapid changes of pattern and colour.

To distinguish any octopus from another you need to know what to look out for in terms of size and colouration. Since divers are so keen to declare to themselves or others that they have seen a mimic octopus, they can often mis-identify other species. Most commonly it is the wonderpus that is mis-identified because it has a similar size, shape and general colour, and also lives in similar habitats to the mimic. An experienced observer will know the wonderpus by the presence of strong white markings which are fixed and therefore do not alter when at rest or in an excited state. Mimic octopus are only believed to have been officially ‘discovered’ as recently as 1998, off the coast of Sulawesi in Indonesia.

Can you spot it here? 🙂 LOL

Feeding habits

Mimics either stalk their prey or can be seen foraging over an area of sand, probing into holes using the tips of their fine arms to flush small crustaceans and fish into its suckers, and from there into its mouth.

Behaviour

It is the behaviour of the mimic octopus that gives it its name and makes it stand out from all other species. Although a lot of human interpretation of animal bahaviour is guesswork, there are strong reasons for believing that when it comes to the mimic octopus you can believe the hype.

Mimicry is commonly used as a survival strategy in nature. However the mimic appears to be able to take on the appearance of not just 1 other species, but of several. The fact that all of the species it imitates are venomous, adds to the likelihood that this is an evolved and deliberate strategy. To the cynics, the mimicry is no more than divers seeing more than what is actually there. So what creatures is the mimic said to err … mimic?

Lion fish – when the octopus hovers above the sea bed, with its arms spread wide and trailing a little from its body, it does not take a great leap of imagination to see the form of a lionfish. In that shape and posture, and with the brown and white stripes, it is indeed conceivable that to the eyes of a potential predator, what might otherwise look like a tasty snack, appears in fact as a highly venomous creature that represents a none-too-appetising prospect.

Sea snake – when the octopus buries all but its eyes and 2 arms below the sand, what remains in view is a long thin object with white and black bands running across the elongated body. Again the prospect of tangling with the highly venomous sea snake is something many predators would not relish, and they therefore may swim off leaving the octopus to live another day.

Sole/flatfish. By pulling its arms together and moving forward along the sandy floor, the body colour and shape and gliding motion all seem to ape that of a poisonous striped flat fish. It has also been said that with a similar motion, but with 1 arm dragging out behind, it imitates a stringray.

Which variation is seen seems to vary depending upon the particularities of the predators in the area. Factors such as the proximity, appetite and environment present may all affect the choice that the mimic makes. According to some scientific observations this theory was reinforced when a mimic octopus under attack by damselfishes, adopted the appearance of the banded sea snake, a predator of the damselfish. There is a longer list of animals the mimic is said to imitate some of which are less convincing than the above examples and include brittle stars, sea shells, jellyfish, Don King, mantis shrimp, anemones, and giant crabs whom they are said to imitate as an apparent mate, only to attack and eat its would-be lover.

Reproduction and Life Cycle

In mating, the male octopus inserts its hectocotylus, a specialised and extended arm, into the female’s mantle cavity, where he deposits packets of sperm. Soon after the hectocotylus falls off(!) and before too long the male will die. The female fertilises, and then carries the eggs in strings while continuing to feed, a feature unusual for octopus. The larvae hatch and shortly thereafter the female dies. The larvae drift as plankton until they mature, when they sink and begin life on the ocean floor.

The mimic is said to live for only around 9 months, which must feel like a maternity!

Predation

Being a fleshy creature with no bones, no spines and no poison, this makes the mimic octopus a very interesting proposal to anything in the sea with teeth and a stomach. In the estuarine conditions that mimics favour this may mean fish including small sharks and barracuda. Therefore it is believed that the mimicry is the form of defence that this octopus has evolved.

Distribution

They seem to be restricted to the Indo- Malay archipelago, and are common around Sulawesi. However, while divers have been poking around reefs for years and years, the kind of diving – muck diving – which takes place in their habitat, has been a reasonably recent pursuit. It may be that mimics are more widespread and found in silty estuarine conditions elsewhere, but only time will tell.

Habitat

Their preferred habitat is relatively shallow water normally less than 15 metres deep where there is a sand or silt substrate, so often this means near river mouths or estuaries. Unlike other reef-dwelling octopuses habitats, there are not hiding places galore within the habitat. Despite this, the mimic forages in daylight which one would expect makes this soft bodied, non venomous creature a prime target for predators. However the mimic clearly thrives in its environment and many believe this boldness is possible only because of its ability to impersonate other venomous creatures.

Ecological Considerations

Very little is really known about the mimic octopus and how their numbers may have fluctuated over time. Given that they often live in marine areas near river mouths, it can be assumed that chemicals released into the water system pose a risk to their numbers in the same way as it would to all marine life in such an area. However there is currently insufficient data on how populations thrive or suffer under different conditions.

Dive Sites

Dive sites in the Indonesia – Malaysia region, where there are volcanic sand sea beds, are the most likely spots for diving with mimic octopus.
