Another nudibranch... and friend

These are from the last two days and I cannot find them in the books that I have.

1) Nudibranch - 80 feet, Okinawa

2) Not very far off from the above nudibranch, it was growing out of the middle of a larger soft coral from what looked like a mass of tangled thick fibers.

Phyllidia ocellata is the first. Those lateral black circles around white-tipped tubercles on an orange background are pretty unmistakeable. The second is a solitary hydroid. They're very difficult to identify even to genus from pictures.
