Thick-horned nudibranch in a Cannon Beach tidepool.
One of the strange little wonders of the Oregon coast.
@Notesfromtheroad Wow. I thought these little drag queens only lived in the tropics.
David - drag queens is a great way to describe them. And actually, some of the most beautiful species are in cold water. Pacific Northwest is great, Northern California has completely different species than us. Some of those really beautiful blue and yellow ones are in cold water Japan. Southern Australia and Tasmania, South Africa...even UK...I have a Norwegian family member whose hobby is UW photography and photographs beautiful nudibranchs!
