What Do Dolphins Eat?
Dolphins are carnivores, which mean they also eat crustaceans, squid, marine animals, fish and smaller animals. Their eating habits also depend on other factors like their species, the habitat and the type of food present in the area. Most dolphins also consume fish like herring, cod and mackerel. If we talk about bigger dolphins like killer whales then they can also hunt other large animals, marine animals and birds. What kind of marine animals? Well they can be sea lions, seals, penguins, walruses, seabirds, sharks, etc. And if you are wondering what do dolphins eat and how do they survive here are few essential facts to know.
How Do they Benefit from one Another with Abundant Source of Food?
- The Bait Balling Technique – Dolphins work in groups to get food and bait balling is the most common technique they follow. They utilize this method to capture a school of fish. Dolphins make a circle around the small fish and this makes them gather in a herd. When dolphins cover all the paths of the fish, they begin eating. This technique makes it easy for dolphins to get food. They also take turns so that every member can get a chance to eat. They are also known to share food with their counterparts.
- Corralling – This is another method that is mostly followed by dolphins in shallow water. In this technique, dolphins get their prey by getting them to a small or narrow place. Once they get their prey there, they pin them against mud or wall so they cannot escape.
- Echolocation – This is a method that they follow to communicate with each other during the hunting process. It helps them create sound waves that further make it easier for them to locate their food. This happens when the sound waves bounce off the objects and then come back to the whales as the emission of the echo. With the help of echolocation, dolphins locate their prey and hunt them for eating.
Dolphins are the most interesting form of aquatic life out there and you already know that they are very intelligent. So, knowing about a creature that is of great help to mankind is surely an amazing thing.
