These amazing marine mammals are capable of impressive problem-solving, social interactions, and using what appears to be a complex communication system. They have a relatively high brain-to-body-size ratio, advanced language and comprehension skills, the capacity to show emotion, and are highly sociable. However, when we consider the size of a human brain vs a dolphin brain, it's not enough to say that the bigger brain is the more intelligent creature. More recently, research has shown thatraccoons have an impeccable memory, and are able to recall solutions to puzzles for up to three years. Compared to dolphins, orangutans are sharp because they understand how to build objectsand why it's necessary.

One parrot named Alex was given the same intelligence tests that were also given to dolphins and apes, and he scored as well in many areasand even better in some. "They are the second most encephalized beings on the planet," says Marino. Dolphins also have an extremely well-developed and defined paralimbic system, which is responsible for processing emotions. They can recognize themselves in a mirror (a feat most animals fail atand a sign of self-awareness). Bottlenose dolphins have bigger brains than humans (1600 grams versus 1300 grams), and they have a brain-to-body-weight ratio greater than great apes do (but lower than humans). Chimpshave a profound memoryaccording to research published inCurrent Biology,their memory may be even greater than humansand a relatively advanced knowledge of tools. to the American Museum of Natural History in New York City. New research suggests that parrots, like dolphins, are capable of mastering complex intellectual concepts that human children cannot handle until age 5.

They found that humans came in the highest, followed by several species of dolphins: Tuxuxi, white-sided, common, and bottlenose. But sperm whales are also massive animals that require more computing power for basic tasks like movement. This makes dolphins second only to humans in brain-to-body weight ratio. However, dolphin brains are quite different from the brains of humans and great apes. By that measure, human brains, by comparison, are seven times average. They'll then delegate responsibility and change jobs. Then there was Billie the dolphin, who was trapped in a sealock and rescued. Other than humans, who possess an EQ of around 7.5,dolphins have the highest EQof any animal, about 5.3. In 2000, behavioral ecologist Peter Tyack proposed the idea that thepitch of a dolphin's whistlefunctions as a means of individual identification like a name. They use their "signature whistles" to announce their presence or let others in the pod know where they are. It's a complicated question because it's hard to compare a whale or a dolphin's intelligence with our own, mainly as we can't use the same methods to measure both. PLOS ONE, vol. But when it comes to behaving and responding to the world in human-like waysone of the chief ways we can compare the intelligence of animals to one anotherdolphins aren't on the same level as chimps. Current tests for intelligence indicate that dolphins do not possess the same cognitive abilities as humans and are thus not the "smarter" species. Researchers, writing in theProceedings of the Royal Society B, have declared that dolphins have the longest-lasting memory in the animal kingdom. Dolphins are mammals capable of problem-solving and engaging in highly social behaviors. Learn more about us, Subscribe to our newsletter below, or contact us for more infomation!

The first scientific attempts to assess dolphin intelligence in a serious way came in the 1950s and 1960s with John Lilly, a scientist that studied bottlenose dolphin vocalization. As demonstrated by their friendly countenances, dolphins are also brimming with personality. 1. Similar to dolphins, rats also demonstrate altruistic behavior; for example, they've been known to free other rats from cages during experiments. 17-74, doi:10.3819/ccbr.2014.90002. , but observations have shown dolphins poking pufferfish and entering a trance-like state of intoxication after presumably ingesting the potent neurotoxins produced by the fish.
