Although it may not be directly meaningful, in terms of brain size, the bottlenose dolphin brain averages 1.6 kg in size, by comparison, the average human brain weighs about 1.35 kg and a chimpanzee’s brain weighs 0.4 kg. A more useful measure is to compare actual brain size with that ...
Along with human beings, dolphins belong to a group of creatures considered to be intelligent. The intellect of these cetaceans is not superior to the human’s, although some scientists believe that the intelligence of dolphins is different and the comparison in human terms is not fair. THE BR...
and some species only have to get air twice per hour. They also have a large brain, the second largest for mammals in comparison to their body size, only after humans. Their brain is very complex, and research shows it
Comparison of the median sulcus among previously reported endocasts and brains of the Cetacea suggests that the cerebrum was expanded incipiently in the Odontoceti from the early Miocene in the Eurhinodelphinidae+ Delphinoidea lineage. Conversely, the olfactory fossa has been reduced in Odontoceti,...
Humans, by comparison, only exchange about 15% of the air in their lungs when they breathe. How Do Dolphins Sleep? Dolphins can never fully sleep. They are not involuntary breathers like humans, which means they must consciously swim to the surface to take a breath. As a result, one ...
