What do dolphins eat?

A dolphin’s diet typically consists of a variety of fish, squid, shrimp, jellyfish, and octopuses. Their diet also depends on the species of the dolphin (there are more than 40 species of dolphin), where the dolphin lives, and the other wildlife that lives around them.

How long do dolphins live?

The life expectancy of a dolphin is affected by their habitat, geography, diet, level of endangerment, health, social structure, and species. Dolphins are able to live for an average of 20 years, and female dolphins tend live longer than males. Dolphins that live in captivity tend to have shorter lifespans than those in the wild.

Where do dolphins live?

Dolphins are able to live in all of the world’s oceans and in some rivers. Not all species of dolphins are able to live in every environment, except for the bottlenose dolphin who is able to live in almost every ocean except for the Arctic and Antarctic ocean. Most dolphins prefer tropical and temperate waters since they are warm-blooded mammals.

What are the three groups of organisms that are considered cetaceans?

The 3 groups of organisms that are considered cetaceans are whales, dolphins and porpoises. The 3 groups are made of 89 species in total. The cetacean order is further divided into 2 groups: toothed whales (odontocetes) that includes over 73 species and baleen whales (mysticetes) that is made up of 11 species.

What do cetaceans eat?

All species of cetaceans are carnivores. A cetaceans’ diet depends on the species, but most cetaceans feed on mostly fish, and marine invertebrates. Some like the killer whale, feed on large mammals and birds like penguins or seals. Baleen whales usually eat mollusks, copepods, krill, small fish, and squid.

Where do cetaceans live?

Cetaceans can be found in all climates and all oceans of the world ranging from the coldest waters to tropical waters. Some species live only in specific areas, like the southern right whale dolphin and hourglass dolphin that only inhabit the Antarctic Ocean. Some species of whales migrate between seasonal habitats like the gray whale.

How are freshwater animals adapted to their environment?

Freshwater animals adapt to their environment through gills that obtain oxygen and allow them to live in rivers and streams in which the water is cooler and has a higher oxygen level. Freshwater animals also need to swim fast to catch food and utilize their environment to create their home.

Why are freshwater animals going extinct?

Freshwater animals are going extinct due to the creation of man-made elements that block migration routes for fish and disrupt habitats. The water withdrawal for human use also shrinks and degrades habitats as well as the draining of wetlands for development depletes habitats. Other reasons include overexploitation, pollution, and global warming.
