In 2014, a massive whale carcass washed up on the beaches of Hong Kong. At first, scientists were stumped. They didn’t know what the creature was. They assumed it was a Bryde whale, until it was later identified at the elusive Omura whale—one of the most mysterious mammals in the world.

Scientists didn’t even confirm the existence of Omura whales until 2003. Since then, only eight of them have been discovered. But each one was a dead specimen—in fact, nobody has ever seen the whale alive, until recently.

Earlier this week, a team of biologists released this footage of the rare Omura whale off the coast of Madagascar. It was the first time the animal has been recorded in the wild.

We know almost nothing about about these animals, according to a 2015 study published by the team’s lead researcher Salvatore Cerchio.

We don’t know how many whales exist in the world. We don’t know for sure what they eat nor what their behavior is like. (Though scientists suspect that the whales consume zooplankton).

We do know that these creatures are small in comparison to other whales. Adults are around 33-38 feet long. Young calves are half the size of a boat, according to the study.

The whales seemingly avoid deep water and shallow coastal waters, while the animal tends to stick to tropical oceans.

Interestingly, most of the whales the researchers observed were alone rather than in a group. Though when one whale was spotted, another whale would be seen in the general area. Even though the animals seemed to be solitary, they could possibly be interacting acoustically.

Cerchio says that these whales are difficult to spot since they live in remote areas and since they don’t have a “prominent blow.”

“This is the first definitive evidence and detailed descriptions of Omura’s whales in the wild and part of what makes this work particularly exciting,” says Cerchio in a statement.

Redditors, of course, commented on the whale’s unique appearance in Reddit’s Interesting As Fuck community.

Others were envious of the whale.

Some users were more pragmatic.
