Sea stars belong to the phylum Echinodermata, which also includes sea urchins, sand dollars, and sea cucumbers. Members of this phylum, called echinoderms, are exclusively marine, have radial symmetry as adults, and use a water-vascular system for locomotion, digestion, and respiration. There are over 2,000 known species of sea stars, and they can be found worldwide - from warm, tropical waters to cold, polar waters 🌊 📍Bahamian Reefs Hope Spot 📸 OShea 📍Henoko-Ōura Coastal Waters Hope Spot 📸 Hope Spot Champions 📍Fish Rock Hope Spot 📸 Fish Rock Dive Center #HopeSpots #SeaStars
