These conditions allowed marine life to flourish and led to wide diversification. It is during this time that sea stars (from the class Asteroidea) and brittle stars (from the class Ophiuroidea) diverged. Sea stars, or starfish, tend to have legs that are wider and more connected to one another. They had tubular feet
