Mammals
Spectacled Porpoise
Phocoena dioptrica
Marked by a bold black eye patch ringed in white that resembles a pair of spectacles, a spectacled porpoise remains one of the least frequently observed marine mammals anywhere in the cold waters of the Southern Hemisphere.
Overview
The spectacled porpoise, Phocoena dioptrica, is a Data Deficient marine mammal native to ocean habitat scattered across cold Southern Hemisphere waters, including around South America, the Falkland Islands, and occasionally South Africa and Australia. Its striking spectacle-like eye markings, sharply contrasting black-and-white body, and rarity of direct sightings make it one of the more visually distinctive yet poorly understood marine mammals found anywhere in the Southern Hemisphere.
A porpoise known mostly from the shore
Far more often found stranded on a beach than spotted alive at sea, the spectacled porpoise has built its scientific record largely from animals that never made it back to open water, leaving huge gaps in what is known about how it actually lives.
Status
Data Deficient, with population size and trends remaining poorly documented across its scattered Southern Hemisphere range, and much of the available information coming from stranded individuals rather than live observations.
Spectacled Porpoise: common questions
Why is it called the spectacled porpoise?
This species has a bold black patch around each eye ringed in white, a striking pattern that resembles a pair of spectacles, giving the species its distinctive common name.
Is the spectacled porpoise commonly seen at sea?
No, this species is rarely observed alive at sea, with much of what is known about it coming from stranded individuals rather than direct sightings of living animals in the wild.
Where is the spectacled porpoise found?
This species is found scattered across cold waters of the Southern Hemisphere, including around South America, the Falkland Islands, and occasionally South Africa and Australia.
Why is the spectacled porpoise classified as Data Deficient?
This species lacks the detailed population data needed for a more precise conservation assessment, since it is rarely observed and much of the available information comes only from stranded animals.
