Rajaustynät

Rajaustynät is a Finnish term referring to the finless porpoise (Neophocaena phocoenoides), a small cetacean native to the Indian and Pacific Oceans. Unlike many other porpoise species, Rajaustynät possess a distinctive lack of a dorsal fin, a characteristic that gives them their name. They are typically dark grey to black in coloration and have a relatively small body size, with adults reaching lengths of around 1.5 to 2 meters. Their diet consists mainly of fish and cephalopods, which they forage for in coastal waters and estuaries.

These porpoises are generally found in warmer, shallow seas and are often observed in small groups. Their behavior is typically shy and elusive, making them difficult to study. Conservation concerns exist for Rajaustynät due to threats such as bycatch in fishing gear, pollution, and habitat degradation. Several subspecies have been identified, each with a slightly different geographical distribution and potential conservation status. The finless porpoise is an important part of its marine ecosystem, contributing to the food web and indicating the health of its environment.
