Although the mere size of the brain is not necessarily an indication of intelligence, scientists have discovered that sperm whales, such as the humpback whale or beluga whales, have spindle cells in their brains. These cells are only found in species believed to have higher intelligence, such as elephants, great apes, & humans. Scientist also believe that whale songs might be part of a more complex communication system that has yet to be fully understood. 6: Sea Otter The sea otter is a marine mammal & is the heaviest member of the weasel family. Unlike other sea mammals, their main form of insulation is a coat of fur that is very thick &the densest in the animal kingdom. Even though it is able to walk on land, the sea otter spends the vast majority of its time in the sea. In fact it is believed that these animals can live their entire lives without ever leaving the water. A significant example of a sea otter’s intelligence is it’s ability to use tools. A sea otter will often use rocks as hammers to break apart shellfish for food. Otter pups raised in captivity exhibit a rudimentary inclination towards tools use, without ever having received training. 5: Orcas Orcas, are toothed whales & the largest member of the oceanic dolphin family. In some instances they have been known to attack other adult whales. They are apex predators meaning that no other creature preys upon them. The orca has the second-heaviest brain among all marine animals & has frequently been described as intelligent. People that have interacted with these animals have constantly offered examples of their playfulness, curiosity & problem solving abilities. According to the fishermen, they figured out the decoys in less than an hour, & solved the problem by splitting into groups. 4: Cuttlefish Like octopuses or squids, cuttlefish are capable of releasing ink from an ink sac whenever they are threatened by predators. They are also characterized by a unique internal shell called the cuttlebone which is used for buoyancy. Historically, jewelers have used the cuttlebone to make casts for various pieces. Their brain-to-body ratio is among the largest from all invertebrates. Cuttlefish are capable of communicating visually in a very fast & diverse manner. The common cuttlefish is capable of displaying 34 chromatic, eight postural, six locomotor & six textural elements which constitute a form of visual language. They are also referred to as the ‘chameleons of the sea’. 3: The California Sea Lion California Sea Lions communicate through a series of vocalizations known as barks. Mothers communicate with their pups through contact calls. These sea lions are particularly intelligent, so much that they may be trained to perform certain tasks. If accustomed to human presence, they display almost no fear & that is why they are a common choice for public display in circuses, zoos, & oceanariums. The United States Navy has even trained these animals to perform particular military operations. A sea lion named ‘Ronan’ was recorded moving it’s head in synchronization to musical rhythms. Another sea lion named ‘Rio’ showed evidence of great memory. 2: Octopuses Octopus are believed to be the most intelligent & behaviorally diverse invertebrate. Marine wildlife experts have identified over 300 species of them, which accounts for more than one-third of the total number of cephalopod species. Octopuses do not have internal or external skeletons, thus allowing them to squeeze through tight spaces. When threatened by predators they defend themselves by hiding, jetting quickly through the water, using camouflage, and/or through the expulsion of ink. Octopus species can be trained to distinguish between various patterns & shapes. Some researchers have claimed that they practice observational learning. 1: Bottlenose Dolphins The Bottlenose dolphin is the most common & well-known member of the Delphinidae family. They are also considered to be among the most intelligent animals in the world. They communicate through whistles, burst pulse sounds & body language. Body language communication movements include slapping the tail on the surface, butting heads, snapping jaws & leaping out of the water. These dolphins have the second-largest brain to body mass ratio, surpassed only by humans. The investigated cognitive abilities include mental representations, sensory skills & concept formation.
