👉 Ophioscincus is a genus in the family Ctenophora, which belongs to the class Nematoda. This group of marine crustaceans are known for their hard, tough exoskeletons and their ability to attach themselves to surfaces through their long, flexible tentacles. Ophioscincus species are primarily found on coral reefs, where they have adapted to withstand high pressure and temperature changes due to the presence of calcium carbonate.
