Dolphin. A dolphin is an aquatic mammal in the clade Odontoceti ( toothed whale ). Dolphins belong to the families Delphinidae (the oceanic dolphins), Platanistidae (the Indian river dolphins ), Iniidae (the New World river dolphins), Pontoporiidae (the brackish dolphins), and possibly extinct Lipotidae (baiji or Chinese river dolphin).
Dolphins feed chiefly on fish and squid, which they track using echolocation, a built-in sonar that bounces sound waves off prey and reveals information like its location, size, and shape.
Jun 29, 2024 · Dolphins are popularly noted for their grace, intelligence, playfulness, and friendliness to humans. The most widely recognized species are the common and bottlenose dolphins (Delphinus delphis and Tursiops truncatus, respectively).The bottlenose, characterized by a “built-in smile” formed by the curvature of its mouth, has become a familiar performer in oceanariums.

A group of dolphins is called a pod. Dolphins are social mammals that interact with one another, swim together, protect each other, and hunt for food as a team. Pod life plays a very important role in protecting dolphins from predators such as sharks. Most pods contain anywhere from 2 – 30 dolphins depending on the species and the situation, however there are occasions when pods gather with ...
Dolphins have the ability to use echolocation, which is a sophisticated biological sonar system.To echolocate, dolphins produce high-frequency clicks which are projected out of their melon (forehead area).Since sound travels faster underwater than is does in air, these clicks travel very fast to a targeted area, bounce off objects and animals in that targeted area and return back to the dolphin.
