Biomechanics of adhesion in sea cucumber cuvierian tubules (echinodermata, holothuroidea).
Several species of sea cucumbers, all belonging to a single family, possess a peculiar and specialized defense system, the Cuvierian tubules. It is mobilized when the animal is mechanically stimulated, resulting in the discharge of a few white filaments, the tubules. In seawater, the expelled tubules lengthen considerably and become sticky upon contact with any object. The adhesiveness of their...
متن کاملAspidochirotida (Echinodermata: Holothuroidea) from the northeast coast of Brazil.
This is a taxonomic work on the aspidochirotid sea cucumbers from shallow waters in Northeast Brazil. We studied 165 specimens, classified into 2 families, 3 genera, 7 subgenera and 9 species. Descriptions, illustrations and literature data are included for each species, in addition to ecological notes and information on their distribution in the northeast coast of Brazil. A taxonomic key is pr...
متن کاملIsolation and Characterization of Adhesive Secretion from Cuvierian Tubules of Sea Cucumber Holothuria forskåli (Echinodermata: Holothuroidea)
The sea cucumber Holothuria forskåli possesses a specialized system called Cuvierian tubules. During mechanical stimulation white filaments (tubules) are expelled and become sticky upon contact with any object. We isolated a protein with adhesive properties from protein extracts of Cuvierian tubules from H. forskåli. This protein was identified by antibodies against recombinant precollagen D wh...
متن کاملReproductive cycle of two commercial species of sea cucumber (Echinodermata: Holothuroidea) from Caribbean Panama
The reproductive status of the holothuroid species Isostichopus badionotus (Selenka, 1867) and Holothuria mexicana (Ludwig, 1875) was studied over 16 months in Bocas del Toro (Panama), from November 1999 to February 2001. Sexual reproduction was evaluated by the gonad index method, and by histology of gonad development. In addition, population structure was assessed based on sex ratio, minimum ...
متن کاملNew Prototrochus species of sea cucumber from Australia (Echinodermata: Holothuroidea: Synaptida: Myriotrochidae).
The case put by Alexey Smirnov in 2012 is accepted and the order name Synaptida Cuénot is adopted in place of Apodida Brandt. Two new Myriotrochidae Théel species from the continental slope of Australia are described: Prototrochus robbinsae sp. nov. and Prototrochus roniae sp. nov. A key to the six Australasian species of Prototrochus Beljaev & Mironov and a distribution and depth map are prov...
