About the Monserrat Chuckwalla

Sauromalus slevini, also known as the Monserrat chuckwalla or Slevin's chuckwalla, is a species of chuckwalla belonging to the family Iguanidae. S. slevini is native to three small islands in the Sea of Cortés. The generic name, Sauromalus, is said to be a combination of two ancient Greek words: sauros meaning "lizard" and omalus meaning "flat". The proper ancient Greek word for "flat" is however homalos (ὁμαλός) or homalēs (ὁμαλής).

Its specific name, slevini, is a Latinized form of the surname of American zoologist Joseph Richard Slevin (1881–1957), who was Curator of Herpetology at the California Academy of Sciences from 1928 to 1957. The species was first described by American herpetologist John Van Denburgh in 1922.

The common name, "chuckwalla", derives from the Shoshone word tcaxxwal or Cahuilla caxwal, transcribed by Spaniards as chacahuala. S. slevini is found on three islands in the Sea of Cortés: Isla del Carmen, Isla Coronados, and Isla Monserrate. It can be found at altitudes from sea level to 489 m (1,604 ft). Due to its restricted range S. slevinii is a CITES protected animal. Wikipedia →
