[134][135][136], Some dolphin species are at risk of extinction, especially some river dolphin species such as the Amazon river dolphin, and the Ganges and Yangtze river dolphin, which are critically or seriously endangered. [68] The age of sexual maturity varies by species and gender. Diet: Dolphins eat a wide variety of foods including squid, octopus, young herring, pilchard, anchovies, nocturnal hake and sardines. [10] One of the hybrids has been bred back to a bottlenose dolphin, demonstrating such hybrids are fertile.[21]. (cf Ino.) Dolphins do, however, lack short wavelength sensitive visual pigments in their cone cells indicating a more limited capacity for color vision than most mammals. As well as this, the eyes of a dolphin are placed on the sides of its head, so their vision consists of two fields, rather than a binocular view like humans have. [130][131] A study at the U.S. National Marine Mammal Foundation revealed that dolphins, like humans, develop a natural form of type 2 diabetes which may lead to a better understanding of the disease and new treatments for both humans and dolphins. Scientists in California in the 1960s concluded there were two species — the long-beaked and short-beaked. Image from: NOAA Fisheries Also known as the Sarawak dolphin , it is a cetacean species in the dolphin family Delphindae. Here, dolphins drive fish towards fishermen waiting along the shore and signal the men to cast their nets. [49], Dolphins are not thought to have a good sense of taste, as their taste buds are atrophied or missing altogether. [56] Most dolphins have slightly flattened eyeballs, enlarged pupils (which shrink as they surface to prevent damage), slightly flattened corneas and a tapetum lucidum; these adaptations allow for large amounts of light to pass through the eye and, therefore, a very clear image of the surrounding area.

The Japanese government recommends that children and pregnant women avoid eating dolphin meat on a regular basis. 231 pp. [104] While some reports state that the dolphins are becoming intoxicated on the tetrodotoxin in the fishes' skin,[105] other reports have characterized this behavior as the normal curiosity and exploration of their environment in which dolphins engage. SCIENTIFIC NAME OF FRASER’S DOLPHIN – In this topic, we are going to know and identify the scientific name of Fraser’s dolphin. Because their group members were spread out, this was done in order to continue traveling together. Lessons from cleaner wrasse and other species." [169], Several scientists who have researched dolphin behaviour have proposed that dolphins' unusually high intelligence in comparison to other animals means that dolphins should be seen as non-human persons who should have their own specific rights and that it is morally unacceptable to keep them captive for entertainment purposes or to kill them either intentionally for consumption or unintentionally as by-catch. In places with a high abundance of food, pods can merge temporarily, forming a superpod; such groupings may exceed 1,000 dolphins.
