Coral reefs are massive piles of sediment produced from calcium carbonate produced by the phylum cnidaria, class anthozoa, order madreporaria, with the addition of calcareous algae and other organisms that produce calcium carbonate. One group of biota that lives in association with coral reefs and plays an important role in the coral reef ecosystem is Chaetodontidae fish. The taking of the Chae…
Blood clams are a type of soft-bodied animal that lives sessile and obtains food by filtering (filter feeder). This results in many microorganisms accumulating in the body of the blood clams, one of which is the coliform bacteria group. Coliform bacteria are divided into two, namely fecal coliform and non-fecal coliform. Fecal coliform comes from animal and human feces, such as Escherichia coli…
