Danionella dracula, or dracula fish is a new species discovered by accident when a shipment of aquarium fish were found to be very different from what the Natural History Museum in London expected. When the fish died, autopsies revealed that instead of teeth, the Dracula fish has bone spike protruding from its jaws! They are native to one particular stream in Burma, but may be lurking in other aquariums all over the world.
Elysia chlorotica pushes the limits of what is plant and what is animal. This sea slug harnesses the power of the sun by eating algae and then incorporating the alga’s chlorophyll into its own system. After two weeks of ingesting algae, the slug can go without eating anything for a year -as long as it’s exposed to sunlight.
Macropinna microstoma, or the barreleye fish has a transparent head and eyes that can roll around inside to see in all directions. The green domes are its eyes; the bits that look like eyes are organs more like nostrils.
