Habitat
Heaviside's dolphins inhabit coastal waters along the western coast of southern Africa, primarily from Namibia to South Africa, favoring shallow areas less than 200 meters deep over sandy or rocky substrates. They are rarely found far from shore and prefer upwelling zones rich in nutrients that support prey populations.
Diet
Heaviside's dolphins primarily feed on small schooling fish like anchovies and sardines, as well as cephalopods such as squid. They hunt in groups using echolocation to locate prey, typically foraging during the day in shallow waters.
Behavior
Heaviside's dolphins are highly social, living in small groups of 2-10 individuals, and are often seen bow-riding boats or performing acrobatic leaps. They are diurnal, active during the day for feeding and socializing, and exhibit territorial behavior in preferred coastal areas. These dolphins communicate with whistles and clicks, and they are generally curious towards humans but not aggressive.
Conservation Status
Heaviside's dolphins are classified as Near Threatened by the IUCN, with a decreasing population trend due to threats like bycatch in fishing nets and habitat degradation from pollution. Conservation efforts focus on reducing incidental captures and protecting coastal habitats.
