Scientists Discover New Beaked Whale Species Off Japanese Coast

Scientists Discover New Beaked Whale Species Off Japanese Coast Scientists have confirmed that small, black-beaked whales spotted by Japanese whalers are an entirely new species, according to a new study. Hokkaido whalers had long referred to two types of whales as tsuchi-kujira, a name that encompassed the Baird’s beaked whale, called Berardius bairdii, and a smaller black whale, called kuro-tsuchi (or karasu, meaning crow). Scientists had previously performed a genetic analysis that revealed the smaller whales didn’t seem to match the tsuchi-kujira. Now they’re ready to declare the whale a separate species, with the name Berardius minimus. It’s an exciting announcement.

A whale shark 's mouth might not seem like the most hospitable environment for a home, but Japanese researchers have found there's no place like it for a Podocerus jinbe—named after the sharks they were first found in —are a variety of gammaridea, a species known for their hardy nature.

The whale shark (Rhincodon typus) is a slow-moving, filter-feeding carpet shark and the largest known extant fish species . The largest confirmed individual had a length of 18.8 m (62 ft)

The tiny inhabitants -- dubbed podocerus jinbe -- are a variety of gammaridea, a species known for their hardy ability to live in environments ranging from high mountains to the deep sea.

But lead researcher Ko Tomikawa, an associate professor at Hiroshima University, said he was "surprised" to find them living in the mouth of an animal.

New whale species called the 'Black Baird's beaked whale' is discovered off the coast of Japan

New whale species called the 'Black Baird's beaked whale' is discovered off the coast of Japan The new species of whale has often been spotted by whalers in the north Pacific Ocean but it has never before been officially recognised as it continued to elude researchers. But the carcasses of several unidentified whales continued to wash up on the shores of Hokkaido, Japan's northernmost island, while others were caught by fishing vessels.

The whale shark is found in oceanic and coastal waters between latitudes 30°N and 35°S. The whale shark is generally a solitary species , but major feeding areas can see aggregations of over The shark catches its prey by either swimming with an open mouth , straining its food from the water

They’re the largest fish in the sea, lumbering quietly in open ocean waters where little has been known about them. The bus-sized whale sharks — docile creatures with a gaping mouth — have recently become endangered, as researchers have been enlisting tourists to help track and identify them.

"This creature, which is usually 3-5 centimetres long, is amazing because they can live in so many different kinds of environment," Tomikawa told AFP.

"But I didn't expect we would find one inside the mouth of a whale shark."

Gammaridea are a type of crustacean, a group that includes water fleas

The researcher said the new variety has a brown-coloured body of about five millimetres long and hairy legs, which help catch organic substances for food.

Whale sharks are known as jinbe zame in Japanese, inspiring their newly discovered residents' name.

And Tomikawa said there were some good reasons the species might choose such an unexpected location.

"The mouth of the whale shark is probably a good habitat because fresh seawater, which is necessary for them to breath comes in regularly, and food flows in too," he said.

"And it also provides a safe place without any predators."

The new variety was discovered after Tomikawa was contacted by an aquarium in southern Okinawa prefecture curious to know what appeared to be living in a whale shark there.

About a thousand of the creatures were found inside the gills of the shark's mouth, he said.
