Habitat
Common bottlenose dolphins inhabit coastal and continental shelf waters in temperate and tropical oceans worldwide, often in bays, estuaries, and shallow areas up to 200 meters deep. They prefer warm waters but can adapt to a range of salinities, including river mouths. Geographic preferences include the Atlantic, Pacific, and Indian Oceans.
Diet
Bottlenose dolphins primarily eat fish such as mullet, mackerel, and herring, along with squid and crustaceans like shrimp. They use echolocation to locate prey and often hunt in coordinated groups to herd fish into tight schools. Feeding typically occurs during the day in shallow waters.
Behavior
Bottlenose dolphins are highly social, forming pods of 2 to 15 individuals that can merge into larger groups for activities like hunting or playing. They are active both day and night, exhibiting playful behaviors such as leaping, bow-riding boats, and using tools like marine sponges. They communicate with whistles and clicks, show territorial behavior in some coastal areas, and are known for their intelligence and curiosity toward humans.
Conservation Status
The IUCN classifies the common bottlenose dolphin as Least Concern globally, though some populations are decreasing due to threats like pollution, habitat loss, and bycatch in fishing gear. Conservation efforts include marine protected areas and regulations to reduce human impacts.
