Green breasted mango hummingbirds are found in Central Mexico and northern parts of South America. Males are recognisable from their glossy, bright green plumage, while females boast a more bronze-green colouration.
Green iguanas’ bodies are covered in soft, leathery scales. Female lizards are a brighter green than males. The spines on iguanas' backs give them a prehistoric appearance. These strange-looking creatures have been known to grow up to 2.3m in length, and are found in Central and South America, and in parts of the West Indies.
Panther chameleons exhibit extraordinary colour variations: the reptiles change colour during courtship and breeding, and males vary dramatically in colour between populations, from emerald green to turquoise or bright pink.
For chameleons, colour can be used for camouflage and visual communication. They can adapt quickly to different environments and for social reasons. Outer layers of skin have pigment-containing cells (chromatophores) which shrink and expand, displaying different colours.
The nicobar pigeon (Caloenas nicobarica) is a pigeon like no other. The only member of its genus, its beautiful, green iridescent plumage is a mark that it has little need for camouflage due to having few natural predators. It is found mainly in South East Asia and the Pacific.
The silk moth is a master of deception. As adults they look like brown, dead leaves, and as caterpillars they fool predators too: their fat green bodies and false eyes fool predators into thinking they are snakes.
A particularly impressive garden insect is the shiny, jewel-like leaf beetle. Only around 1cm in length, the tiny creature shows off an oily looking, iridescent blue-green exterior.
The emerald swallowtail butterfly gets its names from the resplendent stripe of colour across its dark green wings. Found in southeast Asia, the insects’ underside is black with orange and white spots, belying its more colourful upperside.
Green burrowing frogs (Scaphiophryne marmorata) are found in Madagascar. They are also known as marbled rain frogs and sport beautiful, symmetrical markings.
Often underappreciated, algae can be beautiful in its other-worldly appearance. The Chlorophyceae are freshwater green algae - the species name has its roots in the Greek word chloros meaning green.
