Indo-Pacific Humpbacked Dolphins

The Indo-Pacific Humpbacked Dolphins are found in both the Indian and Pacific Oceans. They are also found in the Eastern Hemishphere along the coasts of Asia, East Africa, and Australia. The Indo-Pacific Humpbacked Dolphins are usually found in shallow waters and prefer swimming in warm water temperatures of 15 to 36 degrees celcius.

The Indo-Pacific Humpbacked Dolphins have a stocky body, weighing up to 284kg as an adult and lenghths of 3.2 meters. This dolphin has a well defined beak and is variant in color depending where they live. Some calves are light in color at birth darkening to a dark gray coloring on the upper half, also called the dorsal side, and light gray on the bottom half of their bodies, also called the ventral side. Off the coast of China and in the Western Indian Ocean, calves are born with a dark coloring that changes to a soft whitish pink color with a spotted pattern as they become adults. However the Indo-Pacific Humpbacked Dolphins found near Malaysia and Northern Australia are almost white in color.

The Indo-Pacific Humpbacked Dolphins are suspected to breed year round. Calves are observed in excess after being born between the months of December and February. Much more research is needed on these particular dolphins if we as humans are going to fully understand there breeding habits.

These particular dolphins travel in groups of 10, but have been seen in groups up to 30. The Indo-Pacific Humpbacked Dolphins enjoy sandy bays for resting and socializing together and are slow swimmers rarely seen bow-riding. Although these particular dolphins may be slow swimmers, they are known to chase off and even kill sharks.

The Indo-Pacific Humpbacked Dolphins are found in both tropical and warm temperate coastal waters. They are happiest in water temperatures between 15-36 degrees celcius. These mammals can be found in both the Indian and Pacific Oceans, from Northern Australia and Southern China to Indonesia and around the coastal rim of the Indian Ocean to Southern Africa. The Humpbacked Dolphins are also known to enter rivers, estuaries and mangroves.

The diet of the Indo-Pacific Humpback Dolphin consists of Estuarine and reef fish along with Mollusks and Crustacieans. They feed near the shores in shallow aters. Echolation is used to find food. The Indo-Pacific Humpback Dolphins typically hunt in small groups but have been observed hunting for food individually also.

The Indo-Pacific Humpback Dolphins are threatned by humans as they are known to be hunted for human consumption and also for oil, in different parts of world. They are also known for becoming entangled in fishermans nets and caught in anti-shark gillnets.
