A live-bearer, it is native to southern Tamaulipas and northern Veracruz states in northeastern Mexico. It is a popular fish in the aquarium trade due to its prolific breeding, as are hybrids with other members of its genus, most notably the southern platyfish. Description The variable platyfish grows to a maximum overall length of 7.0 cm (2.8 in). In the wild, they are olive in colour with black marbling or spots on the side of the caudal peduncle.

Seth Eugene Meek
Seth Eugene Meek (April 1, 1859, Hicksville, Ohio – July 6, 1914, Chicago) was an American ichthyologist at the Field Museum of Natural History in Chicago. He was the first compiler of a book on Mexican freshwater fishes. Together with his assistant, Samuel F. Hildebrand, he produced the first book on the freshwater fishes of Panama. He often collaborated with Charles H. Gilbert, and in 1884 on a collecting trip through the Ozarks, they discovered a new species, '' Etheostoma nianguae'', which only lives in the Osage River basin. Also with them on that excursion was David Starr Jordan, considered the father of modern ichthyology. After the Ozarks trip, Meek accepted the post of professor of biology and geology at Arkansas Industrial University (now the University of Arkansas).

Crustacean
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata.

Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of .
