Daftar Isi:
- Semelidae bivalves have ecologically significance in estuaries and shallow waters ecosystems. However, the functional morphology of this bivalve has not been studied. The purpose of this research was to study the morphological characters of Theora lata, one of Semelidae bivalves. Specimens collected from Sidoarjo Coastal Water, Jawa Timur. Specimens relaxed by using MgCl2 7% in sea water and fixed in 10% formalin in sea water. Finally, specimens were preserved in 70% ethanol. Observation was done on the internal morphology of all specimens. Morphometric measurements were done on the length, height, and width of shells, length and width of ctenidium and labial palp. The results of this research showed that the diagnostic characters of Theora lata were exterior and interior characters of the shell, form and the type of siphon, and the form of foot. Ratio length: height of the shell=1: 0,6; ratio length= width of the shell: 1: 0.3, ratio height: width of the shell= 1: 0.6. Based on the morphometric measurements of ctenidium and labial palp, Theora lata can be categorized as deposit feeder. The ctenidium of Theora lata is smaller than its labial palp, the ratio of ctenidium: labial palp is 1: 1.2. Key words: Theora lata, Semelidae, Bivalvia, morphological character of bivalve, deposit feeder
