Cyprinodon brontotheroides is a species of pupfish in the genus Cyprinodon.

Distribution and habitat[]

It is endemic to hypersaline interior lakes on San Salvador Island, Bahamas.

Ecology and taxonomy[]

It coexists alongside two other closely related Cyprinodon species C. desquamator and C. variegatus. Together, these three species represent a recent adaptive radiation, each having moved into a difference niche within their specialized environment. Each of these species are defined by distinct trophic adaptations that have affected various aspects of functional morphology.[2]

Description[]

Cyprinodon brontotheroides is durophagous. It has a large in-lever to out-lever ratio for closing its lower jaw with force and a protruding, reinforced nasal region probably used for crushing its specialized diet of ostracods and gastropods.[3] They breed in the spring and the breeding territories are guarded by the males.[4]
