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.
Diadema antillarum (black sea urchin)
A graph depicts the low oxygen levels and high ammonium concentrations in 2005 that caused large algae blooms. This put more stress on the ecosystem, resulting in the fish kill.

A conceptual diagram illustrates the factors that cause brown tide algae blooms to occur in high magnitudes and what impacts these blooms have on the rest of the ecosystem.
Causes and Impacts of Brown Tide Algal Blooms
As land use in the Chilika Lake area changes from forest to settlements and paddy agriculture sewage, and fertilizer and pesticides runoff increases into the Lake. This extra nutrient input results in algae blooms that float and sit on the bottom.

Pyrodinium bahamense, considered the sister taxon to Alexandrium, is a tropical euryhaline dinoflagellate found mainly in the Atlantic Ocean. P. bahamense is a major cause of seafood toxicity and cause of paralytic shellfish poisoning, especially in Southeast Asia.

An overabundance of algae occurs in ponded areas of Pipe Creek, where animal waste from geese washes into the creek. Increased nutrients from the waste causes algae to grow and bloom. Sandusky, Ohio.
