Spinner dolphin's diet
These species are known to asleep with one brain hemisphere in slow-wave sleep thus vigilant about the potential predators all the time. They cannot breathe into the water and they must show themselves to the surface for air. Dolphins live in social groups of five to several hundred. Like bats, dolphins use echolocation to navigate and hunt, bouncing high-pitched sounds off of objects, and listening for the echoes. Spinner dolphins are generally found in the middle of the ocean. While playing they usually jump over the water surface. By producing whistling sounds these animals tend to communicate with each other. Dolphins will also follow seabirds, other whales and fishing boats to feed opportunistically on the fish they scare up or discard. Dolphins produce several sounds including whistling and burst-pulsed sounds. Dolphins are highly intelligent marine mammals and are part of the family of toothed whales that includes orcas and pilot whales. These species have the ability to swim 260 metres beneath the water surface. They are found worldwide, mostly in shallow seas of the continental shelves, and are carnivores, mostly eating fish and squid. Dolphins predominantly feed on small fish and squid. Dolphins are well known for their agility and playful behavior, making them a favorite of wildlife watchers. There is a significant difference in sizes of several dolphin species. Scientists believe that dolphins conserve energy by swimming alongside ships, a practice known as bow-riding.
Biologists maintain that some of the species believed to have been evolved some 10 million years ago. They use echolocation to find prey and often hunt together by surrounding a school of fish, trapping them and taking turns swimming through the school and catching fish. Dolphin coloration varies, but they are generally gray in color with darker backs than the rest of their bodies. Many species will leap out of the water, spy-hop (rise vertically out of the water to view their surroundings) and follow ships, often synchronizing their movements with one another. This is observed particularly in males as compared to females. Most species live in shallow areas of tropical and temperate oceans throughout the world. Some of the species (Bottlenose Dolphins) have a quite unique way of hunting in that they beat their tail at the surface and start circling around. Here are some of the most absorbing dolphin facts for kids including its diet, species, reproduction and where does it live. Dolphins are the close relatives of whales and propoises. There are about five different kinds of dolphin species. The population of dolphins deems to be greater in places where the food is abundant. It is difficult to estimate population numbers since there are many different species spanning a large geographic area. Though occasionally, dolphins are also found to be engaged in the acts of aggression. Large number of small fishes tends to be trapped inside the circle. They are the most sociable marine animals in that they avidly respond to humans while kept in captivity. However, under captivity dolphins are found to asleep completely because there is no risk of other predators. Dolphins consume a variety of prey including fish, squid and crustaceans. Dolphins are by far one of the most intelligent animals on the planet earth.
