- What is Bathydevius caudactylus and where was it found?
- Bathydevius caudactylus, a new species of sea slug, has been discovered in the midnight zone of the ocean. It's apple-sized, bioluminescent, and unlike any sea slug previously known.
- How does Bathydevius caudactylus catch prey and defend itself?
- The sea slug uses a large, hooded structure to trap crustaceans for food, a unique adaptation for its deep-sea environment. It also uses bioluminescence to distract predators.
- What environmental concerns are raised by the discovery of this new species?
- Deep-sea mining poses a threat to Bathydevius and other deep-sea creatures, highlighting the need for increased understanding and protection of this largely unexplored habitat.
- How was this discovery made and what was the significance of the time delay in publishing?
- Researchers from the Monterey Bay Aquarium Research Institute (MBARI) initially observed the species in 2000 but only recently published their findings after extensive study. The species was named for its "devious" nature.
- What are some of the unique physical and reproductive characteristics of Bathydevius caudactylus?
- Bathydevius caudactylus is a hermaphrodite, possesses a transparent body, and can regenerate parts of its tail that glow when threatened. These features aid its survival in the deep ocean.
