Endangered Hawaiian monk seals face a new challenge: eel squeezed their noses | US news


The Hawaiian monk seal is endangered due to various threats from the fish network to the disease. Now, the besieged species face an unexpected new challenge – the snakes stick to their noses.

The picture of a monk seal with a nose eel was shared this week by a Hawaii-based division of the National Oceanic and Atmospheric Administration (Noaa). This episode was the last eel that appeared in the last two years and surprised the researchers.

Keş We've been watching monk seals intensively for forty years, and it hasn't always happened, yoğun said Charles Littnan, chief scientist at Noaa's Hawaiian monk seal research program. ”It's been three or four times now and we don't know why.“

Researchers first saw a seal with an eel nose attachment in the summer of 2016, sending e-mail to colleagues who initially thought it was a joke. The monk seal program has had so long to develop rules on how to draw eels.

. They're stuck there, so you have to give a hard tugboat to restrain the seal and get the eel,. Littnan said. ”One was really far away, so it was like a wizard's handkerchief number, we just had to keep pulling and pulling“.

Events can lead to potential problems in terms of seals, and even the potential for marine life to affect their diving and nutritional capabilities. The seals often cover their nostrils while submerging their nostrils into water, a process that is blocked by the presence of eel-eating eel. . Having a rotten fish in your nose leads to some problems, L Littnan shouted.

The researchers succeeded in successfully clearing all the protruding serpents from all of the fry eels, but they are still trying to investigate the cause.

One theory is that the seals, which often reproduce their food, throw snakes through their noses. Another is the trapped snake fish, when predators try to prevent the feed of predators for food beneath rocks. In either case, scientists are not sure why this nasal congestion is seen only by humans.

. If I'm supposed to, I can tell you it's one of those weird quirks,. Said Littnan. "If you observe nature long enough, you'll see strange things."

Monks are native to Hawaii and are listed as an endangered species in the US, with about 1,400 remaining. Threats, including fishing and disease, are another challenge along with climate change.
