Taxonavigation

Genus: Ophiocoma

Name

Ophiocoma aethiops Lütken, 1859 – Wikispecies link – Pensoft Profile

Description

Disk rounded (dd = 1.1 to 29.4 mm) and totally covered by fine granulation. The granulation covers the base of arms and the radial shields (Fig. 5D). The ventral side of the disc covered with scattered grains (Fig. 5E). Oral shields large, oblong; longer than wide. Adoral shields small, triangular and not meeting within. Cluster of rounded dental papillae on apex of jaw. Four oral papillae on each side of the jaw, the outer papillae being the largest. Four to five teeth (Fig. 5F). Dorsal arm plates wider than long, hexagonal shape (Fig. 5B). Ventral arm plates quadrangular with circular edges. Reduced lateral arm plates. Arm spines rounded, stout and slightly flattened. Arm spines, three and four, alternating. Two tentacle scales (Fig. 5C). Dorsal side dark brown-black in color. Disk with a brown large spot (Fig. 5A). Ventral arm plates and jaw with lighter dark color (Fig. 5K).

Distribution

Lower California, Mexico, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, Panama, Colombia, Peru, Galapagos Islands (Clark HL 1915[1], Hooker et al. 2005[2], Neira and Cantera 2005[3], Alvarado et al. 2010[4]). In Mexico, from the Gulf of California (Baja California Sur, Sonora, Sinaloa), on the Pacific side of Baja California and Baja California Sur, Nayarit, Jalisco, Colima, Revillagigedo Islands, Michoacán, Guerrero and Oaxaca (Solís-Marín et al. 2005[5], Honey-Escandón et al. 2008[6], Granja-Fernández and López-Pérez 2011[7]). From intertidal to 55 m depth (Maluf 1988[8]). In this study, Ophiocoma aethiops was collected on coral reefs from Nayarit, Jalisco, Colima, Michoacán, Guerrero and Oaxaca, between depths of 2.1 to 26 m.

Remarks

Ophiocoma aethiops is the largest brittle star on coral reefs from the Mexican Pacific. It is associated with live and dead stony coral, rocks, algae and rhodoliths. Juvenile organisms inhabit all the above mentioned substrata, meanwhile adults inhabit the interstitial spaces of live and dead stony corals and rocks. We observed that it is common to find juveniles attached to the dorsal side of the arms and disk of adults; an observation that has been previously recorded by Hendler et al. (1999)[9] for Panama. Ophiocoma aethiops is a gonochoric species without sexual dimorphism (Benítez-Villalobos et al. 2012[10]). On the Estacahuite reef of Oaxaca, females of Ophiocoma aethiops spawn from May to November, while male spawning occurs throughout the year, whereas the spawning of Ophiocoma aethiops in Panama occurs during November and December (Hendler 1979[11], Benítez-Villalobos et al. 2012[10]). Besides the color pattern mentioned in the description of the species, we noted that some specimens can have a large white patch on the dorsal side of the disk, whereas the whole body of other specimens are black-brownish.
