Anatomical features between blue crab and horn corals

Blue crabs have three pairs of walking legs and paddle-shaped rear swimming legs. Males have a strongly tapered abdomen, or "apron," that resembles an inverted T, mature females have a broad, rounded abdomen, and immature females have a triangular abdomen

The outside of these corals have a wrinkled appearance. Horn Coral grows in a long cone shape like a bull's horn. The fossil is the skeleton of the coral animal or polyp. They built these cone shaped structures from calcium carbonate that came from the ocean water.

answer; (i-o) psychologist

an aneroid barometer is different from a mercury barometer in that it provides readings that increase as air pressure increases.
