The Long spine goodnight (sharper than I look) You don&#039;t want to step into me as I will protect myself. <br />
Did you know fish like the endangered species Banggai Cardinal have discovered I also protect their eggs?<br />
The male fish carry their eggs into their mouths for 4 weeks. Then, when they grow bigger, they spit them between my spines. Thus helping my friends to survive. Even without hard labor.

  1. Fantastic creature and capture, Ludo. I remember snorkling in Malaysia where some of these were at the sea floor, rising their spines several meters upwards. Posted 8 years ago
    1. Hi F!
      Several meters, wow, that must have been a sight! Truly long spines. This one was still little with spikes only reaching to about 30cm. Still a thing to evade:) Thx for the promotion!

''Diadema antillarum'', also known as the lime urchin, black sea urchin or the long-spined sea urchin, is a species of sea urchin in the Family Diadematidae.

This sea urchin is characterized by its exceptionally long black spines.

It is the most abundant and important herbivore on the coral reefs of the western Atlantic and Caribbean basin. When the population of these sea urchins is at a healthy level, they are the main grazers which prevent algae overgrowth of the reef.
