Tylomelania perfecta
Species of gastropod
From Wikipedia, the free encyclopedia
Tylomelania perfecta is a species of freshwater snail with an operculum, an aquatic gastropod mollusk in the family Pachychilidae. Tylomelania perfecta, like other members of its genus, is ovoviviparous, meaning it retains fertilized eggs in a brood pouch inside the female’s pallial oviduct until they hatch into fully formed juveniles. This unique reproductive strategy is uncommon among freshwater snails and involves significant maternal investment (von Rintelen & Glaubrecht, 2005). This is the first species of the genus Tylomelania that was described (under the name Melania perfecta) by malacologist Albert Mousson in 1849.
