What is in the picture?

Wow! What Lies Beneath!

I've never heard of Brittle Star before. This 'game' is so informative it's brilliant.

FungiHill, been diving twenty year never seen a brittle star like that, it does look like coral

Never have seen that species of Brittle Star. Usually the 5 legs are quite distinct.

I learned something new today.

FungiHill, "The more ornate brittle star class is Euryalida. These echinoderms have 10 arms on their disks (also known as tetraradial symmetry) with each limb progressively branching into smaller, more delicate tendrils. They are also significantly bigger than average brittle sea stars, having central disks that grow up to 14 inches (35.56 cm) in diameter and arms that can measure up to 27.55 inches (70 cm) in length." This text, from a scuba.com blog post, has the same photo shown above.
