Adaptations of octos to hydrothermal fluid
Since it concerns adaptations to deep-sea environment, I didn't start a new thread but it's a little different from the thread topic. hope it's ok.
I was just reading a paper about physiological adaptations of crabs living around hydrothermal vents and wondered what was the case for ceph species which are known to forage around vents.
These crabs manages to survive high sulphide concentrations due to the ability of the hepatopancreas to rapidly oxidise the sulphide entering the circulation at the gills to non-toxic sulphur compounds.
By doing so, they are capable of surviving sulphide levels that would normally inhibit aerobic respiration and therefore be lethal to other animals.
I guess not much research on this has been done with cephs but it would be interesting to know what sort of mechanism these cephs are using considering their microvillar skin, which might not help them. Does anybody have an idea how they manage to tolerate high H2S levels??
I don't have a clue!
Cheers,
