Abstract

One of various shellfish in Indonesia waters that has high economic value is genus Anadara, especially as an edible marine species. Anadara is traditionally known in the trade as blood cockles. There are approximately 100 species of blood cockles in subfamily Anadarinae, the largest member of family Arcidae. Systematic of Anadarinae still does not provide certainty until now, including because there are many variations between species. Anadara, and Arcidae, in general, is one of the most abundant families of mollusc in tropical waters, and spread out in almost all of the coastal waters and found in the basis of subsystems. Its growth will be better on soft mud substrate than sandy mud substrate. Blood cockles are known as a filter feeder that feeds using gills on plankton, especially on phytoplankton. The demand for blood cockles is increasing, thus encouraging production efforts that do not only rely on harvesting from nature but through cultivation also that has been done in several places in Indonesia, such as in Sumatra and Java. This paper discussed taxonomy and classification, morphology and anatomy, habitat and distribution, reproduction and aquaculture, diet and feeding habit, and economic value of blood cockles.

Abstract

A species becomes endemic if found only in one place and not found elsewhere. Physical, climatic, and biological factors can cause endemism through two commonly known mechanisms, namely "autochthonous" and "allochthonous". The Banggai cardinalfish (Pterapogon kauderni) was an endemic fish from the Banggai Islands waters, Central Sulawesi. Biologically, these fish cannot spread beyond their original habitat. This apogonid fish was endemic due to several main contributing factors. First, slow movement which causes limited habitat distribution. Second, have paternal mouthbrooder characters so that they do not have a larval phase. Third, shows an ontogenetic shift in terms of microhabitat selection. Fourth, has a subpopulation that a criteria of Evolutionarily Significant Unit. This review aims to provide a brief review of the endemism of marine organisms with a case study on the Banggai cardinalfish.
