epibranchial organ
Present in some microphagous fishes and comprises a paired dorsal diverticulum located towards the posterior of the pharynx. In the majority of species it's divided into two sections by additional gill rakers which trap small food particles.
organism
An individual life form that can react to stimuli, reproduce, grow, and maintain homeostasis. There are five main groups, or kingdoms: prokaryotes, protists, fungi, plants, and animals.

foam fractionation
Chemical process whereby hydrophobic molecules are removed from a liquid via rising columns of foam, e.g., the process of organic-waste removal taking place within a protein skimmer.
decomposition
Natural, ecological process in which organic material is broken down into simpler substances which may then be used by other organisms. Typically biotic and carried out by microbes, worms, and other organisms but can also be abiotic and occur via chemical or physical processes such as oxidation or hydrolysis.

epithelium
Refers to layers of cells that line hollow organs and glands or make up the outer surface of the body. Epithelial cells help to protect or enclose organs and most produce mucus or other secretions. They're arranged in single or multiple layers, depending on the organ and location.

biochemistry
The chemical composition of an organism, living system or biological entity; the study of chemical substances and processes occurring within living organisms.
biotic
Consisiting of, associated with or derived from living organisms. Biotic factors in an environment include the organisms themselves plus predation, competition and other interrelationships.
chimaera
An organism, organ or body part containing genetic tissue of more than one type due to mutation, transplant, genetic engineering, etc.. Also spelled 'chimera'.
cladistics
Taxonomical method used to classify species of organisms into clades, each of which contains an ancestor organism and all its descendants, based on synapomorphies (shared derived characters). Cladistic classifications are usually presented in the form of a cladogram.
community
A group of organisms or populations coexisting and interacting with one another in a given region under relatively similar environmental conditions. The different organisms influence each other's abundance, distribution, and evolutionary adaptation.

decomposer
Organism feeding on dead or decaying material aiding the natural process of decomposition by breaking down organic substances which subsequently become nutrients.
detritus
In biology, organic debris most often formed via the decomposition of organisms.
