Skifletch,
here are some pics.
They would be noticeable if the clowns put them in a place you can see them.
Thanks for the information
It's interesting that a clown taking a tentacle into its mouth does not appear to have an adverse affect on the clown. If the clowns have a thicker mucus coat to prevent them from being stung, is this mucus coat continue into the throat? IDK, but it makes you wonder how they really survive in an anemone.
