Amazon molly

📖 Overview

Adults are found in backwaters and quiet pools of streams, sloughs, and ditches, usually over mud. This is an all-female species thought to have originated as a result of hybridization between P. latipinna and P. sphenops. Gynogenesis reproduction is triggered by copulation and stimulation by sperm from males of other species in the genus, either P. latipinna, P. mexicana, P. latipunctata, or rarely P. sphenops.

🥚 Reproduction

Reproduces gynogenetically, meaning once the sperm has penetrated the egg membrane, it takes no further part in the development of the embryo. Eggs develop following copulation and stimulation by sperm from males of other species in the genus, either P. latipinna, P. mexicana, P. latipunctata, or rarely P. sphenops. Viviparous , but there is no nutritional contribution by the mother during embryonic development to compensate for the depletion of stored reserves in the egg as embryos develop .

🌍 Habitat & Distribution

Freshwater; brackish; benthopelagic; non-migratory . Subtropical; 27°N - 25°N North America: lower Nueces River (where possibly introduced) and lower Rio Grande, extreme southern Texas, to Veracruz in Mexico.
