Ontogenetic habitat shift, population growth, and burrowing behavior of the Indo-Pacific beach star, Archaster typicus (Echinodermata; Asteroidea)
Archaster typicus, a common sea star in Indo-Pacific regions, has been a target for the ornamental trade, even though little is known about its population biology. Spatial and temporal patterns of abundance and size structure of A. typicus were studied in the Davao Gulf, the Philippines (125°42.7'E, 7°0.6'N), from February 2008 to December 2009. Specimens of A. typicus were associated with inte...
متن کاملMolecular systematics of some Indo-Pacific asterinids (Echinodermata, Asteroidea): does taxonomy reflect phylogeny?
Asterinid sea-stars represent a cosmopolitan element of the world s shallow marine invertebrate communities. Asterinids are typically pentagonal or stellate in form, with flat ventral surfaces adapted for clinging to hard substrates (Clark and Downey, 1992). Clark (1993) listed 18 genera and 117 species of the Asterinidae worldwide. Rowe and Gates (1995) listed eight genera and 37 species of as...
متن کاملTrophic ecology of deep-sea Asteroidea (Echinodermata) from eastern Canada
Asteroids (sea stars) can be important predators in benthic communities and are often present in ecologically important and vulnerable deep-sea coral and sponge habitats. However, explicit studies on the trophic ecology of deep-sea asteroids are rare. We investigated the diets of seven species of deep-sea asteroid from the bathyal zone of Newfoundland and Labrador, eastern Canada. A multifacete...
متن کاملThe first report of Asterodiscides fourmanoiri (Echinodermata: Asteroidea) from the North Coast of Oman Sea, Iran
Echinoderms with around 7,000 species can be found at all depths of the marine ecosystems. Body shape is radially symmetrical, covered by calcareous plates and five body parts are around a central axis. The class of Asteroidea (also known as starfish or sea star) is one of the most diverse groups within the phylum Echinodermata, including nearly 1900 extant species grouped into 36 families, and...
متن کاملIdentification of sixteen new galactocerebrosides from the starfish Protoreaster nodosus.
Twenty-one galactocerebrosides (1-21), including sixteen new compounds (3-7, 9-17, 19, 21), were identified from a cerebroside molecular species obtained from the chloroform/methanol extract of pyloric caeca dissected from the starfish Protoreaster nodosus. The structures of these galactocerebrosides were determined on the basis of chemical and spectroscopic evidences. Especially, one-pot GC-MS...
