Chondrichthyes
An egg casing or capsule of a skate. About 2 in. (5 cm) long. At the corners are hooked spines (tendrils) that are effectively designed to become tangled in seaweed or glued to the algae as another way to anchor the egg.
Spotted washed up on the beach. Perdido Beach.
There is a high levels of predation on skate eggs (up to 18 per cent in one study) by gastropods that bore through the egg case and suck out the contents.
