Delfin

Delfin is the German term for the marine mammal commonly known in English as the dolphin. In zoological usage, a delfin belongs to the family Delphinidae, a diverse group of toothed whales that includes genera such as Delphinus, Tursiops, Stenella, and Orcinus. There are roughly 40 recognized species, distributed across warm and temperate seas worldwide, typically in offshore and coastal waters.

Delfine are streamlined, with a dorsal fin and a beak-like snout. They have a row of conical teeth and use echolocation to navigate, locate prey, and communicate. They are highly social animals, often traveling in pods that range from a few individuals to large groups; social bonds and cooperative hunting are common.

Their diet consists mainly of fish and squid, with some species showing specialized prey preferences. Reproduction is viviparous, with gestation periods generally spanning about 10 to 17 months depending on the species. Calves are cared for by mothers and may remain with their natal pod for extended periods.

Conservation status varies widely by species. While many delfin populations are of least concern, several species are endangered due to bycatch, pollution, habitat degradation, and noise from ships and industrial activities. Research and conservation programs monitor populations, health, and human impacts, informing protective measures and sustainable fisheries.
