The role of the pelagic crustaceans in the diet of the longnose lancetfish (Alepisaurus ferox) was investigated through the analysis of stomach contents collected in the waters surrounding the Seychelles Archipelago. Crustaceans accounted for 88.4% by prey number and for 73.7% by reconstituted mass during the South-West monsoon. During the North-East monsoon, they remained the main prey group a...

Diversity of the primary groups of contemporary Indo-West Pacific coral reef organisms, including mantis shrimps (stomatopod crustaceans), peaks in the Indo-Australian Archipelago (IAA), reaches a lower peak in East Africa and Madagascar [Indian Ocean continental (IOC)], and declines in the central Indian Ocean (IO) and Central Pacific (CP). Percent endemism in stomatopods (highest in the IAA, ...

Stomatopod crustaceans have the most complex and diverse assortment of retinal photoreceptors of any animals, with 16 functional classes. The receptor classes are subdivided into sets responsible for ultraviolet vision, spatial vision, colour vision and polarization vision. Many of these receptor classes are spectrally tuned by filtering pigments located in photoreceptors or overlying optical e...

Stomatopod crustaceans (mantis shrimp) are aggressive benthic marine predators with extraordinary color vision. When communicating with conspecifics, many stomatopods display conspicuously colored body areas, often in combination with other types of signals such as motion and chemical cues. Some species occupy wide depth ranges (>30 m), where changing light conditions can influence color percep...

The Indonesian-Australian Archipelago is the center of the world's marine biodiversity. Although many biogeographers have suggested that this region is a "center of origin," criticism of this theory has focused on the absence of processes promoting lineage diversification in the center. In this study we compare patterns of phylogeographic structure and gene flow in three codistributed, ecologic...

Although natural light sources produce depolarized light, partially linearly polarized light is naturally abundant in the scenes animals view, being produced by scattering in air or water or by reflection from shiny surfaces. Many species of animals are sensitive to light's polarization, and use this sensitivity to orient themselves using polarization patterns in the atmosphere or underwater. A...

Mantis Shrimp Gonodactylus platysoma was observed during a survey for seaweed-related macrofauna from the intertidal region of Andamans after century. The specimen collected using scoop net, identified based on Kemp (1913) and Ahyong (2001). detailed description, images illustrations are given in this article. reappearance G. century highlights potential revealing rich biodiversity Andaman need...
