Are sea urchins immortal?

“No animal lives forever, but these red sea urchins appear to be practically immortal,” said Thomas Ebert, a marine zoologist at OSU. “They can die from attacks by predators, specific diseases or being harvested by fishermen. But even then they show very few signs of age.

Do sea urchins have babies?

Sea urchins reproduce by sending clouds of eggs and sperm into the water. Millions of larvae are formed, but only a handful make it back to the shoreline to grow into adults.

Several sea urchins, however, including the sand dollars, are oval in shape, with distinct front and rear ends, giving them a degree of bilateral symmetry. In these urchins, the upper surface of the body is slightly domed, but the underside is flat, while the sides are devoid of tube feet.
