Fraser's dolphins or Sarawak dolphins (Lagenodelphis hosei) are marine mammals with a widespread population distribution in the range from the eastern Pacific Ocean to some regions of the Atlantic Ocean and Sri Lanka. These animals are similar in physical appearance to several cetaceans like tropical toothed whales and even form groups with them. The behavior of the Lagenodelphis hosei shows their group nature as they form groups of 10-1000. Fraser's dolphins (Lagenodelphis hosei) form mixed groups with other cetaceans such as tropical toothed whales, false killer whales, melon-headed whales, and short-finned pilot whales.

This marine animal has a large body with small flippers and a thin beak, and the dorsal fin does not show very violent behavior. Like other cetaceans, the Fraser's dolphin role in the ecosystem is through its fishing behavior because this behavior is important as it stops the excessive growth of several marine animals and fish species. Their conservation status and distribution of the Lagenodelphis hosei has given this dolphin species a status of Least Concern according to the International Union for Conservation of Nature Red List. Fishing, hunting, a deficiency in their diet, and lack of habitats for reproduction are a growing threat to their population distribution.

Fraser's Dolphin Interesting Facts

What type of animal is the Fraser's dolphin?

Fraser's dolphins are a marine species of dolphins that are found deep in the Pacific Ocean.

What class of animal does the Fraser's dolphin belong to?

Fraser's dolphins are a type of marine mammals that belong to the cetacean family.

How many Fraser's dolphins are there in the world?

The exact number of these marine mammals around the globe is unknown. However, according to some reports, the eastern tropical Pacific Ocean is home to at least 100,000-289,000 Fraser's dolphins and they require no conservation.

Where does the Fraser's dolphin live?

Fraser's dolphins may be found all over the world in mild, temperate, subtropical, and tropical seas. The anecdotal shreds of evidence suggest that this dolphin may usually be found between 30°S and 20°N. They love deep waters as deep as up to 3300 ft (1005 m) and are frequently seen near surface areas.

What is the Fraser's dolphin habitat?

Fraser's dolphins (Lagenodelphis hosei) are found primarily in the eastern Pacific ocean. To a lesser extent, the distribution range is also observed in the Indian Ocean near Sri Lanka and the Atlantic Ocean. Sightings have also been observed in the regions near several islands such as Hawaii, Sri Lanka, South Africa, south Australia, and the Philippines. Islands near the Philippines are particularly known for dolphin sightings. Tourists and enthusiasts from around the world visit the Philippines to watch this marine species.

Who do Fraser's dolphins live with?

Fraser's dolphins live in big, close-knit groups of 10-100 dolphins. However, according to some reports, they have been seen in groups of up to 1,000 dolphins. Reports even suggest that they also form groups with a few related similar species of whales and dolphins.

How long does the Fraser's dolphin live?

Fraser's dolphins have an average lifespan of 18 years. Females reach sexual maturity between the ages of five and eight, while the male reaches sexual maturity between the ages of 7-10.

How do they reproduce?

This species appears to breed all year with a likely surge during the summer months. Like in other whale and dolphin species, polygamy seems to be the type of reproduction in these mammals. The female has a gestation period of 10-12.5 months and gives birth to a single offspring once every two years, usually in the spring or fall seasons. The average number of offspring produced by the female after a single gestation period ranges between one to two. Every two to three years, female dolphins give birth to a single baby. Once the offspring are born, the mother will breastfeed and care for it until it is old enough to hunt and survive on its own.

What is their conservation status?

The conservation status of this species is considered to be of Least Concern. There are only a few specific locations where Fraser's dolphins have an Endangered status. Some threats to this species include the Fraser's dolphin mortality rate due to excessive fishing. Poachers want to sell their meat to meat markets, supermarkets, and restaurants. They also use their meat as bait for many other marine organisms and this level of hunting poses a threat to these dolphins.

Why is it called the Fraser's dolphin?

The skull was not investigated until Francis Fraser discovered it in 1956. He decided after a careful analysis that it was comparable to species in the genera Lagenorhynchus and Delphinus but not identical to either. By simply combining these two names, a new genus was born. Hose's name is, therefore, a part of the scientific name in honor of him being the first one to find the skull and name this dolphin.
