Mar 17

Today marks Saint Patrick’s Day, a day that traditionally involves the wearing of green. To celebrate, we thought we’d have a look at species on ARKive that are already dressed for the occasion!

Join us as we delve into the animal kingdom and explore the world of all things green…

Stunning macaw

This large, stunning macaw is certainly dressed to impress! The great green macaw has particularly vibrant plumage, with a green body and wings, a scarlet red patch on the forehead, blue patches on the wings, and an orange and blue tail. It lives in rainforests in Central and northern South America, where it is an important ‘flagship’ species for the conservation of its habitat.

Terrific turtle

One of the largest and most widespread of all marine turtles, the green turtle is actually named for the green colour of its fat and connective tissue, rather than its outward appearance. This large reptile takes up to 40 years to reach maturity, and some individuals migrate over 2,000 kilometres to reach their breeding grounds.

Fearsome tiger

Like all tiger beetles, the green tiger beetle has long legs and is a fast runner. This species is named for its beautiful iridescent green body, and is also patterned with yellowish spots on its wing cases. The adult green tiger beetle is a fearsome predator of other invertebrates, and its larvae are also predatory, digging pits in the ground to trap unwary prey.

Migrating dragonfly

The beautiful common green darner is one of North America’s most common and widespread dragonflies, and is one of very few dragonfly species known to migrate. A large insect, it has a green head and thorax, and a distinctive ‘bull’s-eye’ mark on its forehead. The name ‘darner’ is thought to come from the long, narrow abdomen of these dragonflies, which somewhat resembles a darning needle in shape.

Spot the iguana!

A popular reptile in captivity, the green iguana is, as its name suggests, usually a shade of green, although bright orange individuals also occur. This large lizard has an impressive spiny crest along its back and tail, and typically lives in trees, where it feeds on leaves and flowers. However, the green iguana is also a capable swimmer, and may dive into water to escape predators.

Brilliant bird

A small, chunky bird with a short, stumpy tail, the green broadbill occurs in parts of Asia and feeds mainly on fruit. As its name suggests, it has a particularly wide beak and mouth. The brilliant green plumage of this species provides it with excellent camouflage in its forest home.

Fabulous frog

The green and golden bell frog is a large, robust frog with pale green upperparts which are blotched with metallic golden or brassy-brown markings. Despite being a member of the tree frog family, this species spends most of its time on the ground or in water. The call of the green and golden bell frog has been likened to the sound of a motorbike changing gears!

Aquatic giant

Although not the world’s longest snake, the green anaconda is certainly the largest when its large girth is also taken into account. Growing up to nine metres in length, this semi-aquatic giant has olive-green upperparts marked with dark spots, giving great camouflage. It can take prey up to the size of deer, capybaras and even fully grown caimans, killing its prey by constricting it in its coils before swallowing it whole.

Prehistoric fish

The green sturgeon is one of the largest and longest-lived freshwater fish, with a lifespan of around 70 years. This unusual species has remained almost unchanged for over 200 million years, and its rows of bony plates give it a prehistoric appearance. Its body is usually olive to dark green, with olive-green stripes, and although it breeds in freshwater it spends most of its life in the ocean.

Marvellous monkey

Although perhaps not the most obviously green-looking species, the green monkey is nonetheless named for the greenish tinge to its golden fur. This West African monkey is highly social and usually occurs in large groups, spending its time both in the trees and on the ground. Although native to Africa, the green monkey has been introduced to some Caribbean islands.


These species give just a taster of the many shades of green worn by animals on ARKive. Of course, plants have a natural advantage when it comes to dressing up in this popular colour!
