El erizo negro de espinas largas

This is the Long-spined urchin (Diadema antillarum). It is characterized by its exceptionally long spines, and is generally found in crevices between 1-10 meters on coral reefs. However, they can also be found inside tropical lagoons, inland bays, and intertidal areas. This species has experienced a major die-off in the early 80's throughout the entire Caribbean, which is unfortunate, since D. antillarum is the most important herbivore throughout the Caribbean. Therefore, we are aiming to acquire information on the current status of this urchin. By answering the questions in this questionnaire, you will help us gaining information on where and how many long-spined urchins are currently present on coral reefs. By clicking Reportar sus observaciones above, you can participate in the research. If you want to learn more about D. antillarum, or are not quite sure which urchin we're talking about, you can read more at Más información sobre erizos.
