Field Notes

Description:

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.

Habitat:

Spotted washed up on the beach. Perdido Beach.

Notes:

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.
