Red-rimmed melania explained

The red-rimmed melania (Melanoides tuberculata), also known as Malayan livebearing snails or Malayan/Malaysian trumpet snails (often abbreviated to MTS) by aquarists, is a species of freshwater snail with an operculum, a parthenogenetic, aquatic gastropod mollusk in the family Thiaridae.

The common name comes from the presence of reddish spots on the otherwise greenish-brown shell.[1]

The species name is sometimes spelled Melanoides tuberculatus, but this is incorrect because Melanoides Olivier, 1804 was clearly intended to be feminine because it was combined with the feminine specific epithet fasciolata in the original description.[2]

This species is native to northern Africa and southern Asia, but it has been accidentally introduced in many other tropical and subtropical areas worldwide. It has also been accidentally introduced to heated aquaria in colder parts of the world.

Subspecies

Shell description

This species has an elongate, conical shell, which is usually light brown, marked with rust-colored spots. An operculum is present. In some places, such as in Israel, the shells are colored in black or dark brown, probably to help conceal the snail on the background of the basalt rocks of the Sea of Galilee (Kinnereth).[3]

The average shell length is about NaNmm[4] or NaNmm, but exceptional specimens may be up to 80mm long. Shells of this species have 10–15 whorls.[4]

Distribution

This species is speculated to be native to subtropical and tropical Africa (excluding West Africa), Indo-Pacific region, south Asia as well as the Arabian Peninsula[5], or to northern Africa and southern Asia.

in Africa:
in Asia:

Prehistoric localities include Gobero in Niger in 6200–5200 BCE.[9]

Nonindigenous distribution

This species can also be found in artificially-heated indoor habitats, such as aquaria in greenhouses, and similar biotopes:

Nonindigenous distribution in the United States

This species has become established outside of its natural range in large part through the activities of aquarists.[1] These snails were imported to the United States by the aquarium trade as early as the 1930s. Established populations exist from Florida to Texas, and the species may still be expanding its range in the West and Northeast.

Some of these exotic populations have become very large, with densities of being reported from the St. Johns River in Florida.[21] In some cases red-rimmed melanias are believed to have a negative impact on native snail populations.[1]

The nonindigenous distribution includes the United States: Arizona; San Francisco Bay, California; Colorado; Florida; Hawai'i; Louisiana; Montana; North Carolina; Nevada; Oregon; Utah; Texas, and Fall River County in South Dakota,[22] (unconfirmed in Virginia, and Wyoming.)

Ecology

This is primarily a burrowing species that tends to be most active at night.

Habitat

Although normally a freshwater snail, this species is very tolerant of brackish water, and has been recorded in waters with a salinity of 32.5 ppt (1,024 specific gravity salinity).

It is however a warm-climate species. It appears to prefer a temperature range of [1] or of . Research has been conducted to determine the snail's lethal high water temperature, which is about . This information is helpful in the disinfection of fishing gear and research equipment, which otherwise may inadvertently spread the snails to uninfested waters.[23]

This species is resistant to low oxygen levels. The pollution tolerance value is 3 (on scale 0–10; 0 is the best water quality, 10 is the worst water quality).[24]

Feeding habits

This snail feeds primarily on algae (microalgae).

Life cycle

Red-rimmed melania females are both parthenogenic and ovoviviparous. Females can be recognized by their greenish coloured gonads while males have reddish gonads. Under good conditions, females will produce fertilised eggs that are transferred to a brood pouch where they remain until they hatch (parthenogenesis and viviparity).[21] Melanoides tuberculata has 1–64 embryos in its brood pouch. Snails will begin reproducing at a size as small as 5mm or 10mm in length and broods may contain over seventy offspring (iteroparity).[1] The size of the shell of the parent at peak release of juveniles is 20mm. The size of juveniles at birth is NaNmm.

Melanoides tuberculata grows to a similar size as Tarebia granifera, are similar in size at first birth and juvenile output.[25]

It is a r-strategist species.[26]

Parasites

Melanoides tuberculata is known to carry certain parasites which can be dangerous to humans. Pinto & de Melo (2011) compiled a checklist of 37 species of trematode parasites from this species of snail.[27] Eleven of those trematodes are also parasites of human.[27] These snails serve as first intermediate host for parasites which include:[1] [28]

This species is a host for a trematode parasite which has been found to infect an endangered species of fish in Texas, the fountain darter.

Agricultural pests

Red-rimmed melanias can sometimes be an agricultural pest species, as has been reported on Chinese cabbage plantations in Hong Kong.[1]

Aquaria

Red-rimmed melanias are quite commonly found in freshwater aquaria, but opinion in the hobby is divided between those who see them as a pest species, and those who value their usefulness as algae-eaters and substrate-cleaners.[32]
