Introduction: The sea star odontophore is the structure positioned between paired oral ossicles, with which they articulate through proximal and distal processes. internal anatomy structures may be used as taxonomic characters for a precise differentiation species, so it necessary to describe variation throughout growth. Objective: To shape of Luidia superba A. H. Clark, 1917 from specimens Gul...
Ocean acidification and ocean warming compromise the capacity of calcifying marine organisms to generate maintain their skeletons. While many precipitate low-Mg calcite or aragonite, skeleton echinoderms consists more soluble Mg-calcite. To assess impact exposure elevated temperature increased pCO2 on echinoderms, in particular mineralogy microstructure, starfish Aquilonastra yairi (Echinoderma...
The SALMFamides are a family of neuropeptides found in species belonging to the phylum Echinodermata and which act as muscle relaxants. The first two members of this family to be identified were both isolated from the starfishes Asterias rubens and Asterias forbesi and are known as S1 (GFNSALMFamide) and S2 (SGPYSFNSGLTFamide). However, little is known about the occurrence and characteristics o...
Lipid dynamics in the embryos of Patiriella species (Asteroidea) with divergent modes of development
Length-weight relationship (LWR), condition factor (K) and feeding habits of Coilia dussumieri, Nemapteryx nenga Nibea soldado from Santubong Estuary, Sarawak, Malaysia were reported in the present study. The sampling was conducted during non-monsoon season monsoon April to November 2017 at Buntal, Penambir Demak rivers using three-layered gillnets. A total 182 fish samples caught measured for ...
A small species of the seastar genus Henricia Gray, 1840 occurs along the cool temperate Pacific coast of North America from near Sitka, Alaska to just south of Ensenada, Baja California, Mexico. Its small adult size, mottled aboral colors, and benthic external brooding reproductive mode have long been noted, but it has never been formally separated from the larger, free-spawning Henricia leviu...
Abstract Taka Bonerate waters are the third largest atolls in world, rich marine biodiversity, natural structures and aesthetics. Seagrass beds these grow well on small islands, one of coastal ecosystems that support biodiversity have many benefits for humans economic, social cultural aspects. This study aimed to examine diversity, distribution, abundance macrobenthos several islands National P...
