I have some wild rock. Over the course of 6 months, these beautiful hitchhikers have appeared twice, in the same spot on the same rock. They appeared all of a sudden, then disappeared within 48 hours. Once they are gone, there is no sign that they were there in the first place.
You will notice that some of them have what appear to be hydroids shooting off the side of the base. They even seem to emerge right through my coralline algae. I'm not sure what other information you might need to help ID this.
Tahoe61 suggested that they are a type of tunicate. Any other ideas?
