Sharks can survive in extremely hot volcanic waters.

the verdict
INSUFFICIENT LEANING
Recorded sources
2 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that sharks can survive in extremely hot volcanic waters?

Unclear. One report describes sharks living inside an active underwater volcano, and a study notes sharks aggregating at warm power-plant effluent. Neither measures the water temperature, so the claim of surviving in extremely hot volcanic waters is only partially supported.
