A Ukrainian teen enthralled by real time pictures from an underwater digital digital camera off Vancouver Island has helped unravel the secret of just exactly how deep-diving elephant seals eat a seemingly inedible seafood.

In the beginning, Kirill Dudko of Donetsk, Ukraine, did know what he n’t had seen.
The 14-year-old had been viewing real time Web video clip of a slide that is hagfish a digital digital digital camera in Barkley Canyon each time a nose and whiskers starred in the framework the other inhaled the hagfish.
“It was like a horror film, ” the biology lover penned in a message to your University of Victoria, the dry-land house associated with the NEPTUNE Canada camera network that is deep-sea.
“This creature had beenn’t like a fish and I also recognized it had been a mammal due to the nose and moustache. ”
In a contact towards the right times Colonist, Dudko stated he had been perplexed because he would not think any mammal except a whale could dive to this kind of depth — the camera is 894 metres underneath the ocean.
“But it would not seem like a whale, ” he said.
Kim Juniper, NEPTUNE connect technology manager, stated the encounter can potentially have already been missed without Dudko’s eye that mail order wife is keen.
“He had been clever sufficient to understand he’d seen one thing unusual, ” said Juniper, incorporating that the NEPTUNE system encourages resident boffins to greatly help search through massive levels of information gathered through the undersea that is 800-kilometre of fibre-optic cable.
“But we didn’t expect that a 14-year-old will be creating a finding similar to this by himself, ” he said.
After taking a look at the video clip, Juniper consulted marine mammal professionals at Fisheries and Oceans and Oregon State University and figured the mystical diver ended up being a lady elephant seal that is northern.
“They will be the only seals known to plunge that deep, ” he said. “They’re not really much a scuba diving seal as a surfacing seal. They spend 90 per cent of their time underneath the water. ”
Although GPS transmitters have actually recorded the deep dives, the movie may be the very first artistic proof of the way they spend their time underwater, Juniper stated.
But exactly what has caught boffins attention that is how a seal consumed the hagfish, an eel-like, eyeless, mucous-producing creature that even sharks and conger eels are not able to consume it since it blocks their gills.
“They exude so slime that is much it turns water in a five-gallon bucket into jelly, ” Juniper stated.
The slime-producing skin skin skin pores help the hagfish worm into the figures of injured and dead whales and enormous seafood, which after that it consumes through the inside away.
“It’s maybe not just a pretty sight, ” Juniper stated.
Hagfish are based in the bellies of dead elephant seals before, however it had not been known the way the seals consume them without gagging on the slime — until now.
“Now we all know she didn’t bite or chew, she inhaled it, ” Juniper stated. “She developed a vacuum that is low-pressure her mouth. ”
The ocean at that level is dark, and elephant seals would often make use of their whiskers as sensors. However the one in the video clip had the sense to hold off once the lights had been turned on briefly when it comes to digital camera, Juniper stated.
The location is illuminated up just for five full minutes any a couple of hours in order to avoid producing synthetic conditions. “Otherwise it will be a little like viewing bears in the dump, ” he said.
For Dudko, the feeling has strengthened their hope of becoming a marine biologist.
“Biology is my favourite topic at school plus it will be cool if my favourite pastime as time goes on will end up my occupation, ” he said.
“I fork out a lot of the time watching the NEPTUNE movie feeds for me to observe the life of its inhabitants online because I think that the underwater world keeps so many secrets and now it is possible. It really is exciting. ”
