Guppies have many predators, such as larger fish and birds, in their native range. Some of their common predators in the wild are Crenicichla alta, Anablepsoides hartii, and Aequidens pulcher. [35] Guppies' small bodies and the bright coloration of males make them easy prey, and like many fish, they often school together to avoid predation.
Bellamy Reservoir. Following is a list of dams and reservoirs in New Hampshire.. All major dams are linked below. The National Inventory of Dams defines any "major dam" as being 50 feet (15 m) tall with a storage capacity of at least 5,000 acre-feet (6,200,000 m 3), or of any height with a storage capacity of 25,000 acre-feet (31,000,000 m 3).
The most commonly kept species are guppies (P. reticulata), mollies (P. sphenops or P. latipinna), and Endler's livebearers . Members of the genus readily hybridize with each other and so most commercially offered fish are hybrids (with guppies having some Endler, and mollies being a mix of common and sailfin mollies).
The Blackwater Reservoir was formed by constructing a mass concrete gravity dam over ½ mile (800 m) across the Blackwater, the main tributary of the River Leven, with a catchment area of 60 square miles (160 km 2). Water is conveyed along a covered concrete conduit 3.5 miles (5.6 km) long, which also collects water from three side stream intakes.
P. picta forms a clade with P. parae that is a sister taxon to the common guppy, P. reticulata. [2] Some authorities place the species in the genus Poecilia, subgenus Lebistes, along with P. reticulata, P. parae, P. branneri, and P. amazonica; others place it in the genus Micropoecilia along with P. parae and P. branneri.
A species of mushroom-like fungus Rogersiomyces okefenokeensis J.L. Crane & Schokn. 1978 is found in the swamp. The Okefenokee Swamp is home to many wading birds, including herons, egrets, ibises, cranes, and bitterns, though populations fluctuate with seasons and water levels. The swamp also hosts numerous woodpecker and songbird species. [16]
The heart of Blackwater Refuge can be accessed via the Wildlife Drive, which is a paved road—approximately 3.5 miles (5.6 km) in length (or a 6.5-mile (10.5 km) loop) [2] —that takes visitors along the Blackwater River and offers excellent views of the local wildlife. Visitors can drive, bike, or walk the length of the Drive.
Poecilia wingei is a very colorful guppy species, similar to the fancy guppy often found in pet shops. The species was first collected from Laguna de Patos in Venezuela by Franklyn F. Bond in 1937, and rediscovered by Dr. John Endler in 1975.
