Black+sea+urchins

=Black sea urchins= Black sea urchins look scary because they have long black spines but they do not attack humans. But It would hurt if you stood on one because its long spines could go into your foot or leg. If you touch it, it rolls into a ball and the spines sting. Australian black sea urchins can grow to 30 cm long.

Black sea urchins live in the warmer part of Australia. They live in the ocean, in coral reefs. They like to hide in the rocks.

Black sea urchins are herbivorous. That means they only eat plants, mainly algae and sea grass.

They are nocturnal so they come out to feed at night.
