In mammals they have internal regulation of body temp and with it they are able to maintain an optimum

core temp of a certain (and known) temp.

Understand that seashore animals are cold blooded and so operate in different manner, but do they have a way of

buffering temp variables of environment, such as low tide exposed to hot sun in summer and lowtide exposed to cold wind chill in a winter.

Example... is the inside

of a limpet shell, where the animal is, much different in temp than the outer side which is exposed to the elements?

Any body know?

cheers

Thats an interesting one. I wonder also if they buffer the variation or have a mechanism that limits the effect (like limpets having thermally

efficient shells so the temp inside is less extreme than the change outside)?

Yep, the thermal insulation properties of the limpet shell, would be interesting to find out.

Internal and external temp of a beadlet anemone

closed and exposed would be interesting as well, perhaps.

Think the questions are pretty neat.
It is the most hostile of places when considering the environment impacts and variations that the

creatures are exposed to, so I am sure there are some amazing mechanisms in place to combat, protect and/or buffer these factors, in order to survive.

Trouble is... when you discover the shell has a thermal porperty, then the little critters will be harvested and exploited to make firebricks or

something similar.

True it is an interesting thought though.
