This biofluorescent hawksbill sea turtle, spotted near the Solomon Islands earlier this year, is the first of its species ever recorded. Marine biologist David Gruber, who found the creature, has described it as looking like "a bright red and green spaceship."
Reptiles aren't generally known for glowing in the dark, and it's still not clear why this creature glows in neon colors. But there are plenty of other animals who have been getting their glow on for a very long time...
This female glow worm was found blazing a trail of light in Malaysia. And if you think she's cool, consider this: One member of this species, the railroad worm, has an additional red light on its head.
In contrast, it's assumed that the bioluminescence that's emitted from brittle stars somehow deters predators. Most brittle stars produce light in green wavelengths, but there are a few, like this one, who shine blue.
This biofluorescent seahorse was spotted earlier this year during an expedition led by scientists from the American Museum of Natural History. The seahorse is one of 180 species that we've recently learned can glow in the dark.
The reason for this fish's name is pretty obvious. Depending on the species, the photophores on the lanternfish may emit weak blue, green or yellow light. Males also may have different light patterns different than females.
Hanging from a New Zealand cave roof, you'll find these sticky silk threads of bioluminescent glow worm larvae of fungus gnat. The larvae feed on the light-attracted insects that get entangled in the threads.
