Sea Urchin

The Red Sea's spectacular coral reefs face a new threat, marine biologists warn -- the mass death of sea urchins that may be caused by a mystery disease.

Inspired by the sea urchin's intricate mouth and teeth, a team of engineers and marine biologists from the University of California-San Diego has developed a claw-like device to sample sediments on other planets such as Mars.

Heidi Klum is planning a family holiday to Italy and wants her children to eat sea urchin fresh from the sea.
