A sex organ is any part of an animal or plant that is involved in sexual reproduction. The reproductive organs together constitute the reproductive system. In animals, the testis in the male, and the ovary in the female, are called the primary sex organs. All others are called secondary sex organs, divided between the external sex organs—the genitals or externalgenitalia, visible at birth in both sexes—and the internal sex organs.
A planarian is one of many flatworms of the traditional class Turbellaria. It usually describes free-living flatworms of the order Tricladida (triclads), although this common name is also used for a wide number of free-living platyhelminthes. Planaria are common to many parts of the world, living in both saltwater and freshwater ponds and rivers. Some species are terrestrial and are found under logs, in or on the soil, and on plants in humid areas.
Planaria is a genus of planarians in the family Planariidae. When an individual is cut into pieces, each piece has the ability to regenerate into a fully formed individual.

Canariella is a genus of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Canariellidae, the hairy snails and their allies.
Canariella pthonera is a species of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Canariellidae, the hairy snails and their allies. This species is endemic to Spain.
A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. Land snail is the common name for terrestrial gastropod mollusks that have shells. However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and fresh water, and others are relatively amphibious between land and salt water.
Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms.
Caenoplana coerulea, known as the blue planarian or blue garden flatworm is a species of land planarian.
Freshwater snails are gastropod mollusks which live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a shell, with very few exceptions. Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung. Most feed on algae, but many are detritivores and some are filter feeders.
Canariella hispidula is a species of small, air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Canariellidae, the hairy snails and their allies.
The clean-up crew is the term that has been used by many aquarists and vendors since the late 1980s to refer to various small animals commonly sold for use in keeping the reef aquarium clear of pest algae, detritus and parasites.
Ypsolopha canariella, the canary ypsolopha moth, is a moth of the family Ypsolophidae. The species was first described by Lord Walsingham in 1881. It is found throughout North America from sea level up to elevations of 1,830 meters. In Canada it occurs in most provinces, from British Columbia and Alberta to Ontario. It is present in most of the continental United States. It is known from a wide variety of habitats, including mixed wood forests, semi-arid scrubland, prairies and badlands.
Ischnophanes canariella is a moth of the family Coleophoridae. It is found on the Canary Islands (Tenerife).
Planaria torva is a species of planarian in the family Planariidae. When an individual is cut into pieces, each piece has the ability to regenerate into a fully formed individual.
Canariellidae is a taxonomic family of small to medium-sized air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea.
