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 کاملReproductive biology of sea cucumber (Holothuriascabra) in north coast of Qeshm Island, Persian Gulf
Sea cucumber species are commercially important in the world. This study explored the reproductive biology of sand fish sea Cucumber in Qeshmisalnd in the Persain Gulf for a year, from December 2012 to November 2013. The macroscopic study intended to examine the features such as gonad color, gonad weight, their length and diameter, and specify the spawning season. Microscopic examinations inclu...
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 کاملConstituents of holothuroidea. 10. Isolation and structure of a biologically active ganglioside molecular species from the sea cucumber Holothuria leucospilota.
Three ganglioside molecular species, HLG-1 (1), HLG-2 (2), and HLG-3 (3) have been obtained from the lipid fraction of the chloroform/methanol extract of the sea cucumber Holothuria leucospilota. The structures of these gangliosides have been determined, on the basis of chemical and spectroscopic evidence, as 1-O-[(N-glycolyl-alpha-D-neuraminosyl)-(2-->6)-beta-D-glucopyranosyl]-ceramide (1), 1-...
