2. A compact cetacean species belonging to the porpoise group, inhabiting colder coastal seas; characterized by a rounded head and absence of a pronounced beak; commonly confused with similar marine mammals
3. A member of the Phocoenidae family distinguished by its thickset shape and shallow facial profile; lives primarily in cool marine environments and feeds on fish and squid; resembles dolphins but differs in dental and anatomical traits

Etymology: In ancient Greek, "phōkaina" was the name for the porpoise, and it sat beside "phōkē," the word for seal. The two are closely related, and the pairing suggests the Greeks saw the animals as kin, both sleek swimmers of the sea. The exact link between the forms is uncertain, but the seal connection is the usual explanation. The scientific name keeps the Greek root in Latin spelling and became the name of a genus that includes the harbour porpoise and its close relatives. English "porpoise" has a separate history. It descends through Old French from Medieval Latin "porcopiscus," literally "pig-fish," perhaps a reference to the animal's blunt snout. The English and scientific names thus reach the same animal by different routes, one through a seal and one through a pig.
