Like all Cyclura species, the San Salvador rock iguana's diet is primarily herbivorous, 95% of which comes from consuming leaves, flowers and fruits from 7 different plant species such as seaside rock shrub (Rachicallis americana), and erect prickly pear (Opuntia stricta). Iguanas can grow up to six feet in length, including their tails.

The iguanas that live on San Salvador Island today are among the rarest lizard species in the world – the San Salvador Island rock iguana (Cyclura riyeli riyeli). "Iguanas have evolved a behavior where a female actually buries herself alive in sand, lays her eggs, and then 'swims' out, packing the loose sand behind her as she leaves the burrow to hide the eggs from predators," Martin says. All of the Cyclura species are considered critically endangered and unfortunately most of them have been driven to near extinction. During a stop on the shoreline road on the south end of the island, Martin happened to notice what looked like the trace of a fossil iguana burrow on a limestone outcrop exposed by a roadcut. [7] This diet is very rarely supplemented with insect larvae, crabs, slugs, dead birds and fungi. [1] Introduced black rats, raccoons, feral dogs, mongoose, hogs, and cats have taken their toll on the population by direct predation, as have the larvae of a moth (Cactoblastis cactorum), introduced decades ago to the Caribbean, which are rapidly devastating prickly-pear cacti, an important food source for the iguanas.
