    compelling sets of characteristics they have acquired over their 55-60-million-year evolution including echolocation ability and complex social organisation (Hof, Chanis, & Marino, 2005) have created great belief that this order contains some of the most intelligent animals (Simmonds, 2006), with the suggestion that they are second to humans in terms of general intelligence (Reiss & Marino, 2001). Modern cetacean brains are among the largest of all mammals in terms of both general size and in relation to body size, with the largest brain in the animal kingdom being possessed by the sperm whale (Physeter macrocephalus) (Marino, 2004) with a mass of 60% larger than that of an elephant (Marino et al., 2007). It is unsurprising that encephilization (a measure of the size of the brain relative to the body) is commonly linked to cognitive abilities, with some cetaceans having the second highest encephilization quotient after humans (Manager, 2013). A hypothesis put forward by Jerison (1973) that the encephilization quotient is a biological indicator of intelligence, with high encephilization quotients…

    The actual definition of intelligence and the way it can be tested in animals is the biggest problem researchers are running into.

    Though humans and dolphins share intrinsically complex fission-fusion social systems, the scientific studies on their social networks differ. This is because researchers have a different focus when conducting their studies. For humans, researchers are focused on clinical outcomes: lower rates of morbidity and lower rates of mortality involving cardiovascular disease. For dolphins, researchers are focused on the reproduction and survival outcomes. Margaret A. Stanton and Janet Mann, both from the…

Studies show that orca pods even have their own “language” of clicks and whistles which they use to communicate (orcas are not actually whales, they are the largest type of dolphin). Parent dolphins sometimes punish young dolphins for misbehaving, and studies have shown that dolphins are some of…
