Prasinohaema (Greek: "green blood") is a genus of skinks characterized by having green blood. This condition is caused by an excess buildup of the bile pigment biliverdin. [1] Prasinohaema species have plasma biliverdin concentrations approximately 1.5-30 times greater than fish species with green blood plasma and 40 times greater than humans with green jaundice.[1] The benefit provided by the high pigment concentration is unknown, but one possibility is that it protects against malaria.[2][3]

Geographic range

Species in the genus Prasinohaema are endemic to New Guinea and the Solomon Islands.[4]

Species

Species in the genus include:[4]

Nota bene: A binomial authority in parentheses indicates that the species was originally described in a genus other than Prasinohaema.

Etymology

The specific names, parkeri and semoni, are in honor of English herpetologist Hampton Wildman Parker and German zoologist Richard Wolfgang Semon, respectively.[5]
