Information stories declare the li’l spiky blob was pulled up onto a analysis boat through a plastic bag whereas scientists had been amassing coral samples.
The tiny stowaway is suspected to be a juvenile Neolithodes agassizii.

King crabs are simply one in all many non-related species which have arrived at a crab form, because of comparable choice pressures molding their evolution. This phenomenon known as convergent evolution, the place the identical trait can develop in species that are not associated.
It has occurred so typically with crab shapes it has been named carcinization.
King crabs developed from hermit crabs, and misplaced the necessity for a shell residence as much as 25 million years in the past.
Not like true crabs which have eight strolling legs, king crabs solely have six legs for strolling.
