Critically Endangered
Saban black iguana
Iguana melanoderma
The Saban black iguana (Iguana Saban black iguana) is a subspecies (sometimes considered a distinct species) of the green iguana thought to be endemic to the islands of Saba and Montserrat, although external evidence indicates that it may be distributed in other parts of the Caribbean.
Appearance
The Saban black iguana is darker coloured than the other subspecies of green iguana, with colouration deepening in older individuals. It possesses a black dewlap, high dorsal spikes, no horns on the snout, and carries a noticeable black patch between the eye and tympanum. The Saban black iguana (Iguana Saban black iguana) is a subspecies (sometimes considered a distinct species) of the green iguana thought to be endemic to the islands of Saba and Montserrat, although external evidence indicates that it may be distributed in other parts of the Caribbean.
It was described in 2020 as a distinct species, although the Reptile Database classifies it as a subspecies of the common green iguana (Iguana iguana).
Range and habitat
Member populations are found on Montserrat and Saba, as well as on the Virgin Islands and the island of Vieques, and in northern Venezuela, among them several coastal islets as well as the mainland vicinity of Cumaná. The mainland distribution has not been well defined. Recent genetic insights confirm that near-indistinguishable melanistic iguanas (compared to Saba and Montserrat) from Puerto Rico and the Virgin Islands have identical mitochondrial haplotypes as those two populations in the Lesser Antilles.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
In crisis
It has been suggested that the subspecies is threatened by unsustainable harvest for consumption and the pet trade, and by competition with and hybridization from escaped or released non-native iguanas.
