- MORPHOLOGY AND BEHAVIOR
Morphology : slender body. Narrow and slightly falcate dorsal fin. In the Caribbean, only the long-beaked common dolphin, characterized by a particularly long and narrow beak, has been identified so far. Scientists are still debating whether it is a full species (Delphinus capensis).
Color and patterns : dark gray back, light belly and characteristic "hourglass" pattern on the flanks, with white-beige coloration in front and gray in the back.
Body length : 2-2.5 m
Group size : usually few to several dozens of individuals.
Specific behavior : they often get close to vessels and bow ride. It usually dives to few dozen meters for several minutes.
Feeding : it mainly consumes small epipelagic schooling fish, such as anchovy, sardines and mackerel, but may also feed on cephalopods.

 


- DISTRIBUTION
Global distribution : they occur in tropical, subtropical, and temperate waters around the world, from 50° south to 40-60° north.
Sightings in the Wider Caribbean region : the common dolphin is regularly observed only on the continental shelf, from Venezuela to French Guiana.

 

- CONSERVATION
Threats recorded in the Wider Caribbean region : bycatch in active and ghost fishing nets.
UICN Status : LC (Least Concern)
SPAW status
 : classified in annex II of the Spaw Protocol since 1991.
