The nuclear genome [9] (~5.8Gbp) of the North American bullfrog (Rana [Lithobates] catesbeiana) was published in 2017 [10] and provides a resource for future Ranidae research. The specific name, catesbeiana (feminine) or catesbeianus (masculine), is in honor of …

Lithobates catesbeianus (formerly known as Rana catesbeiana) (ITIS) Central and Eastern U.S. (Clarkson and deVos 1986) First introduced to the Western U.S. in the early 1900s (Clarkson and deVos 1986) Most introductions have been associated with escapes from aquaculture operations.

R. catesbeiana is native to the eastern and midwestern USA and southeast Canada. Highly aquatic. Rarely found far from water. Active day and night. Eats anything it can swallow, including mammals, birds, amphibians, fish, and reptiles (it can help to control insect pests).

The American green frog (Rana [Lithobates] clamitans) has been introduced to Washington in a few places. The green frog has supratympanic folds but has dorsolateral folds that are easily distinguished from bullfrogs that do not have this trait.

North American bullfrogs (Rana catesbeiana) are native to the Nearctic region. They are found from Nova Scotia to central Florida, from the East coast to Wisconsin, and across the Great Plains to the Rockies.

Adult American Bullfrogs are usually an olive-green color, with occasional black mottling and bars on the thighs. A small dorsolateral fold starts behind the eyes and curves above and around a large, conspicuous tympanum. The underside is white with sporadic gray mottling.

American bullfrogs inhabit ponds, swamps, lakes, reservoirs, marshes, brackish ponds (e.g., Hawaii), stream margins, and irrigation ditches, especially sites with abundant floating, emergent, or submerged vegetation. They may disperse from water in wet weather and sometimes are found in temporary waters hundreds of meters from permanent water.

Identification: Lithobates catesbeianus is the largest true frog native to Eastern North America (Dorcas and Gibbons 2008). Adults range in size between 9 and 15.2 cm (snout vent length) (Powell et al. 2016).

One of the largest frogs of the genus Rana, which can reach up to 20 cm in snout-to-vent length (SV-L), and up to 800 g in weight. Body robust, with wide, flat head. Skin smooth and plain (no wrinkles, warts or spikes), dominantly pale green with brown spots on the dorsal and lateral parts of the body, including limbs and head.
