> The team says that the discovery is an example of deep-sea gigantism

Are there theories about this phenomenon? Does this explain the historically atypical size of the dinosaurs? Why doesn't it continue to happen? For example, why aren't there giant robins (birds) or tiny ones? Is there not a single eco-system ever where this would be an advantage?

From another article on the same discovery

It does, generally on islands: https://en.wikipedia.org/wiki/Island_gigantism

Humans tend to exterminate them.

This might be a relative of our pill bugs? But there is probably a lot more evolution between them than between, e.g., horses and sharks. Which, by the way, is also bigger than between bony fish and sharks.

I've always been fascinated by pill bugs, also known as "Armadillidiidae" [1] they are such cool creatures. I don't know why, but the fact that they are land-dwelling crustaceans was just interesting to me.

I had no idea something like this size and related existed in the sea! Incredible! I wonder now what the evolutionary tree looks like.

Order Isopoda [1] on Wikipedia if anyone else is interested.

Edit: Corrected Family -> Order - oops! Thank you pvaldes.
