The Hawaiian monk seal became endangered because of range & # 39; threats, from fishing ingranġamenti sickness. Now the beleaguered species facing unexpected new challenge – eels thwarting their streams.
Picture & # 39; monk seal with an eel in her nose was broken this week by division based in & # 39; Hawwa National Ocean and Atmospheric Administration (NOAA). The episode was only the latest incident hung eel occurs in the last two years, the researchers baffling.
"We have been intensely monitoring the monk seals for four & # 39; & # 39 in years, these time anything like this happened," said Charles Littnan, a leading scientist in the Program & # 39; Seal Research & # 39; & # 39 Monaco of Hawaiian; NOAA. "It happened three or four & # 39; times and we do not have an idea why."
The researchers identified the first seal b & # 39; nasal series eel in the summer of 2016, by sending an email to colleagues initially thought it was a joke. Since then happened enough times to program & # 39; monk seal to develop guidelines on how to remove the eel.
"Being stuck is really snug, so you have to restrain the seal and give the eel strong tug to release them," said Littnan. "One of them was really far away so it was like a trick moknu & # 39; magazine, we just had to stay & # 39; pulling and pulling."
The phenomena can cause potential problems for seals in & # 39; & # 39 terms, infections or even by affecting their ability to walk and eat on sea creatures. The seals typically seal their nostrils shut when entering the water, a process hampered by the presence of & # 39; & # 39 eels; the nose. "After moldy fish inside your nose is bound to cause some problems," said Littnan.
The researchers managed to remove b & # 39; successful eel projecting & # 39; outside, all from juvenile seals, but still trying to ascertain why this is happening.
One theory is that the seals, which often re-graze their meals, they simply cast eels through & # 39; their nose. Another is startled eel stuck where you are trying to escape seals as predators for food stuff under rocks. Either way, scientists are unsure why this ignition nasal now being shown by humans.
"If I understand, I & # 39; say it is one of those strange oddities," said Littnan. "If you observe the nature long enough, you will see strange things."
The monk seals are native to Hawaii and are listed in the US as an endangered species, b & # 39; approximately 1400 individuals remaining. The threats include fishing and disease, with the climate change challenge another.
