Photos of invertebrates.

 

I heard a lot of conversations about coral reefs and I expected to see a lot of colourful fishes and almost no invertebrates. Indeed, the most of invertebrates (except some sea cucumbers and, of course, corals) hide during the day somewhere. But when I dived at night I was really astonished! Sea urchins, feather stars, different mollusks, crustaceans were everywhere! Look!
