Mucophagy (literally "mucus feeding") is defined as the act of feeding on mucus of fishes or invertebrates. [1] Also, it may refer to consumption of mucus or dried mucus in primates.
There are mucophagous parasites, such as some types of sea lice that attach themselves to gill segments of fish. [2] In addition, these mucophages may serve as cleaners of other animals, usually fishes. [3]
Another usage of this term is in reference to the feeding organ rich in mucous cells in which water is pumped, feeding particles get entrapped in mucus, and the latter proceeds into the esophagus. [4]
Damselfish are those within the subfamilies Abudefdufinae, Chrominae, Lepidozyginae, Pomacentrinae, and Stegastenae within the family Pomacentridae. Most species within this group are relatively small, with the largest species being about 30cm in length. Most damselfish species exist only in marine environments, but a few inhabit brackish or fresh water. These fish are found globally in tropical, subtropical, and temperate waters.
The greater siren is an eel-like amphibian and one of the three members of the genus Siren. The largest of the sirens and one of the largest amphibians in North America, the greater siren resides in the coastal plains of the southeastern United States.
Kissing gouramis, also known as kissing fish or kissers, are medium-sized tropical freshwater fish comprising the monotypic labyrinth fish family Helostomatidae. These fish originate from Mainland Southeast Asia, Greater Sundas and nearby smaller islands, but have also been introduced outside their native range. They are regarded as a food fish and they are sometimes farmed. They are used fresh for steaming, baking, broiling, and pan frying. The kissing gourami is a popular aquarium fish.

The Stegophilinae are a subfamily of catfishes of the family Trichomycteridae. It includes 12 genera: Acanthopoma, Apomatoceros, Haemomaster, Henonemus, Homodiaetus, Megalocentor, Ochmacanthus, Parastegophilus, Pareiodon, Pseudostegophilus, Schultzichthys, and Stegophilus. A monophyletic group within the Stegophilinae is supported by two characteristics of the lateral line, including Acanthopoma, Henonemus, Megalocentor, Pareiodon, Parastegophilus, and Pseudostegophilus. Acanthopoma and Henonemus have a sister group relationship.

Caudal luring is a form of aggressive mimicry characterized by the waving or wriggling of the predator's tail to attract prey. This movement attracts small animals who mistake the tail for a small worm or other small animal. When the animal approaches to prey on the worm-like tail, the predator will strike. This behavior has been recorded in snakes, sharks, and eels.
The plains minnow is one of the 324 fish species found in central United States. It is a large minnow that was once a common bait fish. The plains minnow requires shallow, slow-moving streams to complete its life cycle. Pollution, dams, and introduced sport fish have caused populations to decline.
Gorgasia is one of the two genera that belong to the subfamily Heterocongrinae. This genus is classified by the behavioral pattern of burrowing 75% of their bodies in the sandy substrate they live in and protruding their upper body into the water current above, giving the appearance that they are planted into the ground. This protruding behavior serves a multipurpose functionality to their survival.
The flame chub is a species of freshwater fish in the family Cyprinidae found only in the United States. Its range broadly follows the Tennessee River from above Knoxville, Tennessee, to the mouth of the Duck River. Historically the species was found in Kentucky, Tennessee, Alabama and Georgia. The preferred habitat of flame chub is in small flowing streams often associated with springs.
Derilissus is a genus of clingfishes belonging to the family Gobiesocinae found in the western Atlantic Ocean.

Haemulon squamipinna is a species of marine ray-finned fish, a grunt belonging to the family Haemulidae. It is found in the western Atlantic Ocean where it is endemic to Brazil, here it is locally known as Xira Amarela, and occurs along the coast from the states of Ceará to Bahia. It grows to about 20 cm (7.9 in) in length, feeds at night on benthic invertebrates, and is important for subsistence fisheries along the northeastern Brazilian coast. It forms large schools that can number in the thousands, sometimes with Haemulon aurolineatum. Juveniles are often found in shallow reefs at depths of 2 to 5 m while adults are found in deeper areas at 5 to 30 m.
Erik Bertelsen was a Danish ichthyologist, who specialised in deep sea fish. The fish, Diaphus bertelseniNafpaktitis, 1966 is named in his honour.
