Atlantic Spotted Dolphin

Fascinating facts about the Atlantic Spotted Dolphin

• In the Bahamas Atlantic spotted dolphins have been seen mating with bottlenose dolphins, demonstrating the ability to interbreed across genera. Genetic work by Rich LeDuc suggests the spotted species is genetically closer to Tursiops than to other Stenella members. Studies from the 2020s attribute this closeness to past hybridisation and incomplete lineage sorting, a process called reticulate evolution.
• Only fully mature Atlantic spotted dolphins display a dense coat of black and white spots that cover the entire body, while calves lack this pattern. Newborns are a uniform grey-white colour with at most a single spot. Between three and four years old they begin speckling, a phase that lasts about five years, followed by a mottled stage around eight or nine years when grey and white spots merge on the back and black spots appear underneath.
• Atlantic spotted dolphins are capable of diving to depths of up to 60 m and can remain underwater for as long as ten minutes. They use this ability during nocturnal cooperative hunts, where groups encircle schools of small fish, benthic invertebrates and squid. By diving deep they can access prey that hide near the seabed, and the extended breath-hold lets them maintain the chase without surfacing.
• Atlantic spotted dolphins are extremely gregarious, routinely forming pods of five to fifteen individuals. These groups often include common bottlenose dolphins, creating mixed-species social networks that can be quite complex. Their fast swimming ability fuels frequent bow-riding and long, shallow leaps that are a hallmark of the pods. Such cohesion also means the pod readily defends pregnant females, reinforcing the tight social bonds within the group.
• A female Atlantic spotted dolphin carries her calf for roughly eleven months before birth. After delivery, the mother, supported by the rest of the pod, looks after the youngster for as long as five years, during which the calf remains closely tied to the group. This extended care period allows the young dolphin to learn hunting techniques and social cues from older members.
