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...

The presence of boundaries to dispersal has been recently documented for many Indo-West Pacific (IWP) species with planktonic propagules and a widespread distribution. We studied the phylogeography of the mangrove crab Neosarmatium meinerti (Brachyura: Sesarmidae) and the phylogenetic relationship to its presumed sister species N. fourmanoiri in the IWP in order to compare intraspecific with in...

A new species of sparid fish, Dentex carpenteri, is described from nine type specimens collected off Ningaloo Reef near Exmouth, Western Australia. Four valid species of Dentex are currently known in the western Pacific, Dentex abei and D. hypselosomus in the Northern Hemisphere, and D. fourmanoiri and D. spariformis in the Southern Hemisphere. These four species comprise the "Dentex hypselosom...
