At the Aquarium of the Pacific in Long Beach, they have an exhibit of eggs laid by oviparous sharks. In a stunning display of awesomeness, those clever aquarium scientists have removed part of each egg’s leathery exterior and replaced it with clear plastic, so you can see the baby sharks developing inside. They’re tiny and wriggly and attached to little placenta-ish things. They are mesmerizing.
I assume that the purpose of this is either the pursuit of knowledge or part of a marine-specific antiabortion campaign. In the case of the latter, it is definitely the shark equivalent of “Your unborn baby already has fingernails!”
