Are corals an animal?
yup…some of the most primitive animals still alive today are crynoids, which mainly inhabit coral colonies…stoney corals have a calcium skeleton which grows in small increments (mm’s per year)…unfortunaley,, the majority of stoney corals are undergoing a rapid extinction, exibiting bleaching (where the live animal dies leaving only the white skeleton behind…many scientists contribute pollution pesticide runoff and global warming…soft coral do not have a calcium skeleton and are mainly classified as polyps or mushroom corals…all corals (especially stoney corals) need nutrient poor clean water to thrive, as well as basically unchanging water temperatures.
