Habitat
Hector's dolphins inhabit shallow coastal waters around New Zealand, typically within 10-15 kilometers of the shore and in depths up to 100 meters. They prefer areas with sandy or muddy bottoms near river mouths and bays, avoiding open ocean habitats.
Diet
Hector's dolphins primarily eat small fish such as anchovies and mullet, along with squid and crustaceans like shrimp. They hunt in small groups during the day, using echolocation to locate prey in murky coastal waters.
Behavior
Hector's dolphins are highly social, forming small pods of 2-10 individuals, often seen playing or bow-riding boats. They are diurnal, most active during the day for feeding and socializing, and exhibit curious behavior towards humans but are not territorial. These dolphins communicate with whistles and clicks, and they migrate short distances seasonally based on food availability.
Conservation Status
Hector's dolphins are classified as Endangered by the IUCN, with populations declining due to bycatch in fishing nets and habitat degradation from pollution. Major threats include boat strikes and reduced prey availability from overfishing.
