Info
The Indo-Pacific bottlenose dolphin is one of three species of the genus Tursiops known to date and is widely distributed from the Red Sea, the east coast of Africa through the Indian Ocean and into the Indo-Pacific.
Its back is dark gray and its belly is lighter grayish or almost white with gray spots.
On the menu of this bottlenose dolphin are mainly fish, followed by squid and finally in very small proportions crustaceans,
Investigations showed the following proportions: Fish about 87%, cephalopods about.13%, the few crustacean findings showed that these armored marine animals are eaten only secondarily.
Indo-Pacific bottlenose dolphins live in groups of 5 - 15 animals, but larger aggregations of up to several hundred animals can be encountered, often these large groups move together in search of food through the seas.
Indo-Pacific bottlenose dolphins in Shark Bay, Australia, are said to have a symbiotic relationship with sponges by performing what is called "sponging."
A dolphin breaks off a marine sponge from the seafloor and holds it in its mouth, apparently to examine substrates for fish, possibly as a tool or simply for play.
The mating season of these bottlenose dolphins occurs from spring to summer, and the gestation period is 12 months.
Females can become pregnant every 4-6 years, and newborn dolphin calves range in length from 0.84 cm to 150 cm and can weigh between 9 and 21 kg.
Calves are nursed by their mothers for up to 2 years and often remain in the mother's immediate environment for up to 5 years to learn for life.
Enemies:
Although bottlenose dolphins are fast swimmers, they repeatedly fall prey to their greatest predator, the tiger shark, though completely healthy and strong animals are less likely to be preyed upon than old and sick dolphins.
Life Age:
If the Indo-Pacific bottlenose dolphin does not succumb to disease, sharks or fishing hooks, or perish in nets, they can still live up to 40 years.
Marine mammals such as dolphins and whales are listed and studied in the Conservation of Cetaceans and Their Habitats in the Pacific Islands Region, see also https://de.whales.org/.
Albinos also occur from time to time in Tursiops aduncus, see https://www.bizsiziz.com/extremely-rare-albino-dolphin-spotted-in-africa-possibly-for-the-1st-time-ever/.
Synonym: Delphinus aduncus Ehrenberg, 1832
