Phenolases in the Echinoid, Diadema antillarum Philippi
Nature, 1951Diadema antillarum possesses an abundant black pigment which shows the chemical and histochemical properties of melanin, and is concentrated in epidermal chromatophores1. In view of much evidence from other forms of a relationship between the occurrence of melanin and phenolases, evidence of such enzymes in Diadema was sought.

Recruitment-limitation in open populations of Diadema antillarum: an evaluation
Oecologia, 1990Empirical evidence from studies of the sea urchin Diadema antillarum suggests that this organism widely disperses its offspring, that both recruitment and mortality rates are independent of local densities, and that local food availability does not regulate local population sizes.

Protracted recovery of long-spined urchin (Diadema antillarum) in the Bahamas [PDF]
Coral Reefs, 2022 In 1983–1984, an unknown waterborne pathogen caused the mass mortality of long-spined sea urchin (Diadema antillarum) across the Caribbean and western tropical Atlantic. After approximately 15 years, urchin populations began to recover at some locations, yet few have reached pre-mortality densities.

Alarm Response of Diadema antillarum
Science, 1970Diadema antillarum possesses a sensitive escape response to juices of crushed conspecific sea urchins. Stimulation usually results in urchins moving rapidly downcurrent. Strong species specificity of the response suggests that it is an adaptation to reduce predation. Diadema antillarum also responds with

Pigmentation in the Radial Nerve of Diadema antillarum
Nature, 1968RECENT examination by phase-contrast microscopy of teased, fresh or macerated radial nerve, or of frozen sections in Diadema antillarum, has shown the presence of reddish cells that are neither amoebocytes nor chromatophores, but which resemble neurones in their general form (Figs. 1 and 2).

Potential omnivory in the sea urchin Diadema antillarum?
Regional Studies in Marine Science, 2015Abstract Sea urchins are one of the most important herbivores of shallow-water reefs in the Western Atlantic, capable of controlling seaweed communities. One of them, Diadema antillarum Philippi, 1845 has been target of several studies due to its capacity to control algal communities, and it has been considered a generalist herbivore species ...
