Nudibranchs are so cool

This was in the mess of photos that we took at the beach last Saturday, and tho they are small, nudibranchs are cool.

They are the hard rockers of the beach world, with spiky hair and all. They crawl around the beach, rocks and swim (sort of) in tide pools, and eat sea anemones. The stinging cells, they swallow with nary a thought, and those same stinging cells end up at the end of their "hairs," so they won't get eaten.
