Yes, button corals are poisonous if we touch them
Yes, button corals are poisonous if we touch them
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.
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.
Sea anemones, cucumbers & urchins, stinging/fire corals, crown-of-thorns starfish, hydroids/fireweed, box jellyfish, and irukandjis...just to name a few.
Some species of coral are actually poisonous. Coral is composed of tiny little animals called polyps, that create the hard, white skeleton we know to be a coral reef. The tissues of the polyps create the unique colors of each species of coral as they live together in groups, but some species carry toxins. When brushed or scraped against, the polyps in the coral skeleton will release their toxins as a method of self defense. This can be quite painful and can cause serious rashes, allergic reactions, infections and scarring. Wounds from poisonous corals must be treated immediately with antibiotics to prevent increased tissue damage.
No, corals are not edible.
