Delphin

Delphin is the German word for the dolphin, the common name for toothed marine mammals in the family Delphinidae. The term derives from Latin delphinus, which in turn comes from Greek delphis, reflecting the long-standing recognition of these animals in classical literature. In zoological usage, dolphins belong to the order Cetacea, suborder Odontoceti, and the family Delphinidae; the genus Delphinus contains several species, among them the common dolphin Delphinus delphis and the long-beaked dolphin Delphinus capensis. However, taxonomy varies by authority, and some classifications treat certain groups as subspecies of a single species.

Delphins are highly social and intelligent animals. They typically live in groups called pods and use sophisticated echolocation to hunt and navigate. They feed primarily on fish and squid and display a range of cooperative hunting and social behaviors. Reproduction yields usually a single calf after a gestation period that varies by species; calves are cared for by their mothers for extended periods.

Dolphins occur in most marine environments, from coastal areas to open oceans, across tropical, subtropical, and temperate regions. Some species prefer warm shallow waters, while others migrate long distances seasonally.

Conservation: Dolphins face threats from human activities including bycatch in fisheries, pollution, habitat degradation, and noise. Conservation status varies by species, with several populations considered vulnerable or endangered. International agreements and protected areas aim to reduce threats and promote sustainable practices.
