Jan 18

The third Monday in January is advertised as being the most depressing day of the year. This might be just be a bunch of pseudoscience but we’re here to brighten up this particular Monday in January with some of the natural world’s most amazing blue species.

Forget about The Smurfs, Dory, Aladdin and the Cookie Monster– nature’s got its own pretty cool line-up of blue characters.

1. Blue-footed booby

Blue-footed booby

These rather comical-looking characters use their fabulous bright blue webbed feet as part of their mating rituals. The male birds strut their elaborate feet in front of prospective mates. The bluer the feet, the more attractive the mate. Just check out those dance moves…

2. Sun-tailed monkey

Sun-tailed monkey

 First described in 1986, males of this Vulnerable African monkey species have a rather conspicuous bright blue scrotum.

3. Blue shark

Blue shark

The graceful blue shark is easily identified by its beautifully coloured slender body with deep indigo-blue across the back and vibrant blue on the sides. Unfortunately, this striking species is one of the most heavily fished sharks in the world, with an estimated 10 to 20 million individuals caught each year.

4. Parson’s chameleon

Parson's chameleon

The largest chameleon in the world might look rather blue but it’s only temporary. Like all its fellow chameleon species, the Parson’s chameleon is capable of colour change and it’s not just for camouflage. This rather bizarre-looking lizard with its independently-moving eyes and fused toes is thought to change colour in response to other chameleons (when fighting or mating) and temperature.

5. Dyeing poison frog

Dyeing poison frog

The bright colouration of this alluring frog species is thought to function as a warning to predators that it is poisonous. The dyeing poison frog is named from an old legend in which native people used the frog to change (dye) the plain green feathers of parrots into red feathers.

6. Southern blue-ringed octopus

Southern blue-ringed octopus

Named for the small, iridescent blue spots it develops when alarmed, the southern blue-ringed octopus is one of the world’s deadliest venomous animals. The toxin in its venom is 1,000 times more powerful than cyanide.

7. Blue pipe

Blue pipe

A member of the iris family, the blue pipe is one of the many species of Gladiolus that grow in the incredibly biodiverse Cape Floristic Region of South Africa. The blue pipe is a geophyte, meaning that it is capable of surviving long periods of unfavourable conditions by using an underground food storage organ. During the dry season, the above ground parts of the blue pipe die back, but the plant persists in the soil as a short, swollen stem known as a corm. When it rains, the dormant corm is triggered to renew its above-ground growth, causing the plant to flower once again.

8. Ribbontailed stingray

Ribbontailed stingray

The brightly-coloured skin of the ribbontailed stingray acts as warning colouration to alert other animals that it is venomous. Distinctive blue stripes also run along either side of the tail, which is equipped with one or two sharp venomous spines at the tip, used by the ray to fend off predators.

9. Common blue damselfly

Common blue damselfly

This beautiful damselfly is one of only two species of damselfly that can be found in both Europe and North America, its range almost completely circling the Northern Hemisphere.

10. Blue whale

And finally, even the largest animal to have ever lived, the blue whale, rocks the colour blue!
