I have taken 100's of pictures of Anemone fish. I liked the Sea Anemone in which this fish is hiding.
What is a Sea Anemone that most people mistake for a plant?
Sea Anemones are a group of water dwelling, predatory animals of the order Actiniaria; they are named after the anemone, a terrestrial flower. As cnidarians, sea anemones are closely related to corals & jellyfish. They have long tentacles that catches their prey (very small things).
The Sea Anemone in this picture has white bulb ends with a green nipple topped off with a purple spot. Not a common color scheme.
What adds to the confusion is we call the fish that hide among the Sea Anemone's
tentacles an "Anemone Fish". There are many type of Anemone fish with specific names most of us cannot remember.
The most famous is the "Clown Anemone fish" from the Walt Disney movie.
The fish have names as Clarks, Pink, Tomato etc.
