Most corals have attach themselves to underwater objects and remain there for life. Some corals possess toxins that make them unappetizing to underwater creatures.
Corals are a bunch of tiny animals together; that's why you shouldn't touch it (other than it being sharp, and sometimes poisonous). Seaweed is a plant, similar to a grass on land, I believe.
soft corals live deeper water than hard corals because soft corals do not create a hard outer skeleton as the hard corals do.
cnidocytes are specilized cells where nematocysts are storednematocysts are poisonous harpoons that are stored like coiled springscnidocytes are unique to the phylum Cnidaria (corals, sea anemones, hydrae, jellyfish, etc.).
Corals are not decomposers. They are consumers.
Corals are plants.
Hermatypic corals contain zooxanthellae (a symbiotic algae), whereas ahermatypic corals do not. It is like saying that hermatypic corals are photosynthetic, where ahermatypic corals are non photosynthetic.
Sea anemones, cucumbers & urchins, stinging/fire corals, crown-of-thorns starfish, hydroids/fireweed, box jellyfish, and irukandjis...just to name a few.
Corals capture microscopic particles from plankton floating or swimming past their tentacles. Their nematocysts (organs on their tentacles that can release a whiplike thread sometimes tipped with poisonous spikes) hold and kill their prey. Some corals obtain most of their food by eating zooxanthellae, a type of algae with which the coral have a symbiotic relationship.
No, corals are not edible.
