Yes! It is a dolphin fact that some species live in rivers. South and Central America along with Asia and India boast the worlds river dolphin population. Sadly, it is generally believed that the âChinese River Dolphinâ found only in the Yangtze river, became extinct in 2006. We must all do whatever it takes to learn about, protect, and preserve animals like these. The larger species live far out in the oceans and generally travel in groups or âpodsâ. These pods can reach up to a couple of thousand dolphins in number.
Dolphins are carnivores. They eat fish, frogs, crabs, squid, and many other things found in the water. Their diet is largely whatever is around to eat but fish is preferred. Fish, such as mackerel, are very dense, calorie wise, and high in fat content. They have to eat far more, say squid, to get they same amount of energy. It is a dolphin fact that some species, like the bottle nose dolphin, will eat 5 to 10% of their body weight daily. A 250 kg dolphin (550 lbs) will eat 10 to 22.5 kg (20 to 55 lbs) of food every day if available. Thatâs a lot of fish!
How fast can a dolphin swim? It is difficult to be exact in how fast each species can swim. Killer whales can reach speeds of 20 to 25 miles an hour. Bottle nose dolphins are slightly slower at around 22 miles an hour. It is important to remember that dolphins donât zip around at these speeds all the time. Those are only bursts of speed for a short time. Normal or cruising speed is closer to 7 miles per hour.
Dolphins donât see like we do. Most dolphins have poor eyesight. They move around by using sonar or âecholocationâ. It is a dolphin fact that they can find a 2.5 cm (About the size of a quarter) object from 72 meters (or almost 80 yards) away! The dolphins biosonar is highly developed and enables them to see things in very complex ways. Often dolphins will use sonar from many different spots to get a clearer picture of whatâs ahead of them.
Â Dolphin Brains
Although there is some debate as to how intelligent dolphins are there is no debate that they are intelligent! It is a dolphin fact that they identify themselves and communicate with each other with clicks and whistles. The dolphins brain has two hemispheres like humans and is about the
