Family of marine mammals
Phocoenidae is a family of marine mammals related to the oceanic dolphins, river dolphins, and other toothed whales of the suborder Odontoceti¹. They lack a distinct beak, and their head is either rounded or conical. The dorsal fin is low or absent, the tail fin is narrow with a shallow notch, and the flippers are short ². The common name is derived from the Latin porcus (“hog” or “pig”) and piscinus (“fish”), as their flesh was said to taste somewhat like pork ¹.

Countries with porpoises
China is home to the critically endangered Yangtze finless porpoise, which is endemic to the Yangtze River and its tributaries. It is also the only country where the Indo-Pacific finless porpoise occurs in freshwater habitats.
China
Canada has a large and diverse porpoise fauna, with six species occurring in its waters. These include the harbour porpoise, the Dall's porpoise, the Pacific white-sided dolphin, the northern right whale dolphin, the spectacled porpoise, and the rare vaquita.
Canada
The United States shares some of the same porpoise species as Canada, such as the harbour porpoise, the Dall's porpoise, and the Pacific white-sided dolphin. It also has the Gulf of Mexico subspecies of the vaquita, which is the most endangered marine mammal in the world.
United States
The United Kingdom has the highest density of harbour porpoises in Europe, especially in the North Sea and the Celtic Sea. It also hosts occasional sightings of the rare spectacled porpoise and the Atlantic white-sided dolphin.
United Kingdom
Peru is one of the few countries where the Burmeister's porpoise, a poorly known and elusive species, can be found. It also has the common dolphin and the Chilean dolphin in its waters.

The Fast and Curious Cetaceans
What do you think of when you hear the word porpoise? You might think of a dolphin, but porpoises are actually a different type of cetacean. They have several features that distinguish them from their dolphin cousins.
Life cycle
Birth
Porpoise calves are born tail-first in water.
Echolocation
Porpoises use echolocation to navigate and hunt in murky waters.
Socialization
Porpoises are social animals that form small groups or pods.
Predation
Porpoises are preyed upon by sharks, orcas, and humans.

Largest breed
Dall's Porpoise
Smallest breed
Vaquita
A marine mammal that has a torpedo-shaped body, bulbous head, small blunt snout, flippers, and a tail fin.
The porpoise ear is acoustically isolated from the skull by air-filled sinus pockets, which allow for greater directional hearing underwater.
When swimming, they move their tail fin and lower body up and down, propelling themselves through vertical movement, while their flippers are mainly used for steering.
Porpoises produce ultrasonic clicks, which are used for both navigation (echolocation) and social communication.
