Radial Symmetry
No, anything in phylum Cnidaria (including corals) have radial symmetry
Yes they do, most aquatic animals like coral and stuff like that have radial symmetry.
Coral Reefs
The meandering ridges and valleys of brain coral give it the appearance of a mammalian brain.
Reacent studies show that they are actually both. hard to understand but very tru.
Coral is sharp because it is made of calcium carbonate, a hard substance that forms into tiny, sharp structures called "polyps." These structures help coral to protect itself from predators and provide support for its skeleton.
Yes, coral does have exoskeletons made of calcium carbonate. These exoskeletons provide structure and support for the coral polyps, which are tiny organisms that secrete the calcium carbonate to build the coral reefs. Over time, these exoskeletons accumulate and form the large coral reef structures we see in the ocean.
