The black sea urchin, also called a long-spined sea urchin, 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

Illustration of Prorocentrum minimum (Dinoflagellate) . P. minimum is a bloom-forming planktonic species in temperate, brackish waters to tropical regions; mostly estuarine, but also neritic. Due to its small size, often lost or overlooked in field samples. Cells are active swimmers. P. minimum is a toxic species; it produces venerupin (Hepatotoxin) which has caused shellfish poisoning resulting in gastrointestinal illnesses in humans and a number of deaths
