Inventory of the Echinodermata collection from the Universidade Federal de Alagoas.

Collections and inventories provide important and essential information for understanding the composition and distribution of biodiversity. The collections were made over a period of more than 20 years, at several localities of coastal Alagoas. This echinpdermata now includes 16, catalogued individual specimens, with 50 species in the five extant classes Crinoidea, Asteroidea, Ophiuroidea, Echinoidea and Holothuroidea, based on records; the class Ophiuroidea is best represented.

The results of this inventory contribute significantly to knowledge of marine benthic diversity from the state of Alagoas, and the information presented here expands the data for Echinodermata from the northeastern coast of Brazil. As coletas foram realizadas ao longo de mais de vinte anos em diversas localidades da costa de Alagoas.

Such data is the principal source of information on biodiversity distribution, providing knowledge of areas yet unexplored, and also reveals local extinctions and reductions in species distributions Nogueira et al.

In Brazil, knowledge of zoological collections ehinodermata still sparse, especially for the North and Northeast regions. In the Brazilian Northeast, other specific collections with Brazilian specimens of Echinodermata have been established more recently in universities in the states of Bahia Manso et al.

The first reference to the phylum Echinodermata for the Brazilian coast was based on notes published by Verrill fllo, when this group was still called Radiata, based on samples collected in the Abrolhos area off southern Bahia.


Later, Rathbun surveyed the distribution of species echimodermata Echinodermata. The first catalogue of echinoderms from the Brazilian coast was made available by Brito Several studies and remarks about the fauna of Echinodermata along the Brazilian coast have been contributed, especially by Tommasi The diversity of Echinodermata from the west coast of the Atlantic Ocean was described by Hendler et al.


Xavier dchinodermata the literature and listed species of Echinodermata from the Santa Catarina coast. Albuquerque investigated the fauna of Ophiuroidea from the northern and northeastern continental shelf. The catalogue lists 16, individuals in the five extant classes Crinoidea, Asteroidea, Ophiuroidea, Echinoidea, echinorermata Holothuroidea. To date, the collection includes records representing 50 species. The class Ophiuroidea is best represented, followed by the class Holothuroidea.

Classes Asteroidea and Echinoidea include fewer families, with different numbers of genera and species. Only one family and a single species of the class Crinoidea are represented.

Most of the Echinodermata species were collected from reef ecosystems. The reefs provide different substrata composed by algae, corals, and sponges, and of these, macroalgae harbored most individuals of Ophiuroidea and Holothuroidea.

Specimens of classes Asteroidea, Echinoidea, and Crinoidea were recorded on coral and echinoderrmata reefs, and some species of Asteroidea and Echinoidea were also found on echinodermatq bottoms. The class Ophiuroidea is the most abundant taxon recorded for the Alagoas coast, with 14, individuals, in seven families and 19 species Table 1.
