The Low Tide zone is usually covered by water. This is the lowest zone closest to the open water. This zone is only exposed to air during extreme low tides. Most of the animals here do not need to be adapted to the air because of its low exposure to air. Sponges, fish, snails, crabs, worms, cucumbers, and nudibranches are abundant in this zone. Nudibranches are wormlike creatures that have their gills exposed and not covered or protected. The name nudibranch actually means naked gill explaining that its gills are out in the open. Because of these exposed gills, they usually are equipped with poisonous slime or are bad tasting to predators.
