  • The cerebrum (C), which is the thinking part of the brain was not very big and they had massive olfactory lobes (OL), for the sense of smell, jutting out in front. After the shift the brains got more developed and larger and the cerebrum became massive. They also lost their olfactory lobes. On the upper right is a modern bottlenose dolphin brain.

Bottlenose dolphin brains are larger than many other mammals of the same body size. Scientists are still determining what aquatic adaptations require the large brain size. One likely theory is that a larger brain size in dolphins may be at least partially due to an increased size of the auditory region to facilitate sound processing.

Humans have the highest EQ at 7.4, but bottlenose dolphins have EQs of 5.3, significantly higher than all other animals. This figure may be also be distorted by environmental demands; a dolphin needs much more blubber than a human just to maintain body temperature, so the ratio may be somewhat skewed and the dolphin EQ is effectively lowered from a real comparison point. Without the need for ...

Bottlenose dolphins have the third largest encephalization levels of any mammal on Earth ... It has no olfactory nerves or olfactory lobe in the brain. Bottlenose dolphins are able to detect salty, sweet, bitter (quinine sulphate), and sour (citric acid) tastes, but this has not been well-studied. Anecdotally, some individuals in captivity have been noted to have preferences for food fish ...

There are at least three species of bottlenose dolphins: the common bottlenose dolphin (Tursiops truncatus), the Burrunan dolphin (Tursiops australis), and the Indo-Pacific bottlenose dolphin (Tursiops aduncus). These playful mammals have the largest brain mass per body size of any animal except humans. They display high intelligence and ...

The brain surface area of a bottlenose dolphin is more than 1,400 square centimeters larger than a human being’s. Strong connections between the sensorial and motive areas of a dolphin’s brain to the body indicate that it is very much sensitive to pain and stress. Dolphin Tool Use. While many believe that primates are the only species who use tools for activities, dolphins studied in the ...

Bottlenose dolphins have a few, sparse hair follicles around the tip of their rostrum, though any individual hairs that are present fall out before or shortly after birth. Dolphin skin is highly specialized and plays an important role in hydrodynamics. Upon close observation, cutaneous ridges may be seen on the surface of a dolphin’s skin that run circumferentially around the body trunk and ...

Dolphin brain size with respect to body size ranks between that of apes and humans. The hypertrophic auditory structures, the large cerebrum with extended gyrification and the highly cognitive capabilities of toothed whales seem to be in paradoxical contrast to their thin neocortex with a plesiomorphic or paedomorphic cytoarchitecture.

Interestingly, though, dolphins have been found to possess more than twice as many neurons in the neocortex (the largest and most recently evolved part of the brain) as humans. Specifically, long-finned pilot whales (a type of dolphin) have an estimated 37.2 billion neurons in the neocortex, whereas humans scarcely have 16 billion.

What kind of intelligence does a bottlenose dolphin have?

Numerous investigations of bottlenose dolphin intelligence have been conducted, examining mimicry, use of artificial language, object categorization, and self-recognition. They can use tools (sponging; using marine sponges to forage for food sources they normally could not access) [5] and transmit cultural knowledge from generation to generation, and their considerable intelligence has driven interaction with humans.

What kind of melon does a bottlenose dolphin have?
