Spotted dolphins mainly eat small fish and squid. They have also been known to eat pteropods and isopods, which are free-swimming sea slugs. They use echolocation to help them find their prey.Know More
Spotted dolphins form schools that can include less than 100 individuals but may include thousands. They are known to associate with schools of yellowfin tuna, possibly due to their similar diet. The association could also be for protection, however. This association can also lead to spotted dolphins being killed in fishing nets meant to catch yellowfin tuna.
The feeding habits of female spotted dolphins often changes when lactating. Lactating spotted dolphins eat more fish than other spotted dolphins, including those that are pregnant. This is probably because the lactating dolphin needs more energy than others. At equal amounts, fish provides more protein and more energy than squid. A fish diet also assists with lactation by providing phosphorous and calcium. Because fish are hypotonic with sea water, eating them helps reduce the amount of water the lactating female loses.
Spotted dolphins live in tropical and subtropical areas of the Atlantic Ocean, Pacific Ocean and Indian Ocean and are the most commonly found cetaceans in the Gulf of Mexico. Some of them live inshore, but most live offshore because the deeper water has a more consistent temperature.Learn more about Marine Mammals
As mammals, baby dolphins survive on milk for the first few years of life, although they may learn to catch fish at only a few months of age. Over time, dolphins depend less on milk and more on fish and squid.Full Answer >

There is disagreement among researchers about the intelligence level of dolphins. Previous research portrayed dolphins as keenly intelligent, able to mimic observed actions and quickly reap rewards from learned behaviors. However, newer research portrays dolphins as a species that has superb cognitive abilities yet average animal intelligence.Full Answer >
Dolphins are warm-blooded, not cold-blooded. This is because dolphins are classified as marine mammals, rather than fish. Dolphins maintain consistent body temperature just like other warm-blooded animals.Full Answer >
