- TAXONOMY
Class : Mammalia
Order : Cetartiodactyla
Infraorder : Cetacea
Parvorder : Odontoceti
Family: Delphinidae
Common names:
English: Melon-headed whale
Spanish: Delfín cabeza de melón
French: Péponocéphale


- MORPHOLOGY AND BEHAVIOR
Morphology: somewhat pointed snout and no beak. Relatively robust body, compared to other small delphinids. Stocky and slightly falcate dorsal fin.
Color and patterns: Dark body, except for the grayish belly and the white lips.
Body length: 2-3 m
Confusion with other species: It is difficult to differentiate it from the pygmy killer whale, whose head is more rounded, and which has a dark cape that descends on the sides of the body, below the dorsal fin.
Group size: usually several dozen to few hundred individuals.
Specific behavior: often associated with other small oceanic delphinid species when travelling. When resting, they usually form typical very compact groups. This highly gregarious species is well known for mass strandings.
Feeding: feeds mainly on small deep-sea oceanic fish and cephalopods, when they rise to few hundred meters from the surface, at night.


- DISTRIBUTION
Global distribution: they occur in tropical and subtropical waters of all oceans, from 35° south to 40° north.
Sightings in the Wider Caribbean region: The species is common in the whole Wider Caribbean region, but it is mainly observed over continental slopes and insular slopes.


- CONSERVATION
Global IUCN status: LC (Least Concern)
SPAW status: The Melon-headed whale is classified in Annex II of the SPAW Protocol since 1991.
