help Indo-Pacific Bottlenose Dolphin FAQ

How is the Indo-Pacific Bottlenose Dolphin different from the common bottlenose?

The Indo-Pacific bottlenose dolphin (*Tursiops aduncus*) is generally smaller and possesses a longer, more distinctly spotted belly compared to the common bottlenose dolphin (*Tursiops truncatus*). Their ranges also differ, with the Indo-Pacific species strictly found in the warm waters around the Indian and western Pacific Oceans.

Do Indo-Pacific Bottlenose Dolphins use marine sponges as tools?

Yes, certain populations of this species in Shark Bay, Australia, are famous for their use of marine sponges as foraging tools. The dolphins break off cone-shaped sponges and wear them over their beaks to protect their faces from sharp rocks and stingrays while hunting on the seafloor.

What do Indo-Pacific Bottlenose Dolphins typically eat?

Their diet primarily consists of bottom-dwelling and reef-associated fish, as well as cephalopods like squid and octopus. They often forage in shallow coastal waters, where they use unique hunting techniques like hydroplaning to trap schools of fish against the shore.

Where is the geographic range of the Indo-Pacific Bottlenose Dolphin?

This species inhabits the warm, shallow coastal waters, estuaries, and reefs of the Indian and western Pacific Oceans. Their range extends from the eastern coast of Africa and the Red Sea, stretching eastward to northern Australia and southeastern Asia.
