Sea cucumbers live at the bottom of ocean but there are also floating varieties. When threatened, they can regenerate self, if a predator attempts to severe them. They are known to eject their digestive system. Due to the wide range of their size and shape not all will crawl to a more favorable area, hence the floaters.
In no reading is there any indication of forming a 'resistant spore.' It is problematic that many are caught before sexual maturity. They can reproduce asexually and by regeneration.
I think some might opt to choose 'A' but that has little to do really with the environmental conditions but more to do with feeling threatened.
B tends to be a weak answer because if the environmental conditions were unfavorable, a lot of crawling would be necessary to go to another environment, which is more favorable, where floating requires minimal energy.
Because there are so many varieties of this creature, the answers that offer a regional solution wouldn't work in the one size fits all remedy.
If the sea cucumber is in an unsuitable environment, it will slowly shrink as it digests its own body mass to survive. They could live up to six months without eating.© BrainMass Inc. brainmass.com September 27, 2022, 10:17 am ad1c9bdddf>
