When their population becomes high, the worms migrate toward the surface of the water for access to higher concentrations of oxygen. [citation needed] Although detritus worms may not cause harm to aquarium fish, their appearance is an indication of poor water quality mainly due to overfeeding and lack of good water sanitation. [5]
Horse feces and straw are forms of detritus, and are used as manure. In biology, detritus (/ d ɪ ˈ t r aɪ t ə s / or / d ɛ ˈ t r ɪ t ə s /) is organic matter made up of the decomposing remains of organisms and plants, and also of feces. Detritus usually hosts communities of microorganisms that colonize and decompose (remineralise) it.

Detritivores (also known as detrivores, detritophages, detritus feeders or detritus eaters) are heterotrophs that obtain nutrients by consuming detritus (decomposing plant and animal parts as well as feces). [1] There are many kinds of invertebrates, vertebrates, and plants that carry out coprophagy.
The Global Forum on Food Security and Nutrition suggests edible insects as a solution to the “rising costs of animal protein, food and feed insecurity, environmental pressures, population growth ...
A three-branched intestine runs across almost the entire body, and includes a single anterior and two posterior branches. The planarian intestine is a blind sac, having no exit cavity, and therefore planarians uptake food and egest waste through the same orifice, located near the middle of the ventral body surface. [5]
Planaria is a genus of planarians in the family Planariidae. Due to its excellent ability to regenerate, species of Planaria has also been used as model organisms in regeneration studies. [ 1 ] When an individual is cut into pieces, each piece has the ability to regenerate into a fully formed individual. [ 2 ]
The food of P. torva consists of freshwater gastropods, tubificid worms, and freshwater arthropods, such as isopods of the genus Asellus and chironomid larvae, although it shows a clear preference for snails. [3] In the United Kingdom, P. torva is a successful predator of the invasive New Zealand mud snail (Potamopyrgus jenkinsi). [4]
