Meet the Jamaican rock iguana. Its scaly body stretches around two feet long, tail not included. Slate blue spikes stick up along its spine, and a saggy sac of loose skin wraps around its head like a hoodless cowl. When cornered, it strikes with its front claws — one reportedly ripped an eye from a dog.

Once common in Jamaica, this iguana is now among the most endangered species in the world. And without the hard work of many conservationists, it would probably be extinct. Now those conservationists are hopeful that a decision that appears to have been made about the construction of a seaport in Jamaica could make restoring this lizard to the wild a little easier.

Despite its armored appearance and tenacious lizard traits, the Jamaican iguana has barely survived a variety of threats: hunters, predators like mongooses (but also feral dogs, cats and pigs) and more recently habitat destruction for charcoal production. In fact, it was thought to be extinct until 1990, when a hog hunter’s dog sniffed out a living, breathing animal in the forests of Hellshire Hills in Jamaica.
