Bullfrog
Rana catesbeiana

Description:  These are largest frogs in the US and reach lengths of 8-9".  They have large back legs and are great jumpers.  Their backs are usually greenish , often with an irregular pattern of darker markings. Males have large eardrums, and are often less distinctly patterned.   Their call is a loud booming roar.  Juveniles make a high pitched chirruping distress call as they jump into the water to avoid predators. 

Habitat:  This species should occur near semi-permanent water throughout the area.  It particularly favors slower moving water and ponds.  We have not confirmed its occurrence in the Nueces Canyon.

Distribution:  This species occurs throughout most of the state, but is native to only the eastern 3/4s of the state.  It should occur throughout the Nueces Canyon, but we have not confirmed its existence here.

Abundance:  It is probably uncommon and its occurrence needs to be confirmed for the Nueces Canyon.

Conservation Status:  abundant statewide and their status is secure.

Comments: Their legs are often sold as "frog legs".  This species needs to be confirmed for the Nueces Canyon.
