ocean cucumbers may not have the most exciting of report . Yes some of them expect fabulous , but to be fair they ’re shaped like a vegetable and it was remember they moved about as fast as one too . Not so , says a young field . ocean cuke are astonishingly speedy .
harmonize to brand unexampled research published in theJournal of Animal Ecology , they can up control stick and zip around the sea by blowing themselves up like a balloon and riding ocean currents . passably bang-up , huh ?
Sea cuke are often bring up to as ocean slugs thanks to their deadening social movement and sedentary modus vivendi , though they are not true ocean slug , which are technically ocean - lie in gastropods . alternatively , sea cucumbers are echinoderms , more nearly related to starfish .
Like sea star , it was think that ocean cucumbers crawled about slowly on the sea floor , chilling out and hoover up any food particles they come in across on the seabed . As with most bottom - dwell ocean beasties , if they do move about it ’s in their larval leg , before they become adult and get otiose .
Now , researchers take by Annie Mercier of the Mercier Lab at Memorial University , Canada , have fall upon that they really have a very efficient way of life of traveling longsighted distances , and , of trend , they have a really unearthly means of doing it .
“ They take up piss from all the orifices they can , include through the anal retentive opening , ” Mercier toldNational Geographic . Which should n’t be surprising , since sea cucumbers use their anus for everything frompooping(obviously ) to attacking predators byejecting their own intestines(surprise ! ) .
To study this behavior in the lab , the squad prove their reaction to increase levels of table salt or sediment by create potent stream and storm conditions . Within minute the unimpressed cucumber vine gathered themselves up and fled . Some even increase their urine - to - pulp tuner by 700 percent , for a speedier getaway .
Data pull together in the field clocked some of these cucumbers zipping around at a speed of 90 kilometers ( 56 miles ) per day , which is even faster than their speed as larvae .
Though only observed in two mintage so far , this knowledge that sea cucumber vine may move much further than mentation could be life-sustaining for the selection of the coinage . Tasty to both animals and human beings , 16 species of sea cucumbers are listed on the IUCN ’s Red List of endangered metal money , mainly thanks to demand in Asia .
With instinctive neckcloth use up – the daintiness can go for hundreds of dollar sign – commercial sportfishing effort are decimating ecological habitat , and local fishing resource , in their desperation to get their hand on them . This unexampled information entail that previous population estimation in certain placement may be wrong , affecting conservation efforts and fishing quota in the future tense .
