Anolis bimaculatus spotted in the Quill Crater

While STENAPA rangers in Statia informed Jill and Gavia that the green tree lizard (A. bimaculatus) could not be found in the Quill National Park, that didn’t stop them from looking.

Lizard gold mine discovered in Anguilla

Anolis gingivinus is a species living on the edge… the edge of the barren, spikey, coral island of Anguilla. Luckily Jill and Gavia’s love of the beach led them to stumble upon Katouche Bay, which doubles as a beautiful beach and an anole gold mine!


Making progress in the two species island of Grenada
