HI MIUI Users,
Vampire of the Deep
Vampyroteuthis infernalis, literally "vampire squid from hell," is a mysterious deep-sea species. Research published in September 2012 in the journal Proceedings of the Royal Society B reveals that these strange animals "fish" for ocean detritus using a long filament appendage, seen here in white.
The Vampire's Mouth
Vampire squid get their name from their cloak-like webbed arms. The squid's mouth is at the center of its arm web. Finger-like projections on the arms may help the animal move food to its mouth.
Feeding Vampire Squid
This close-up view shows a vampire squid using its arms to scrape food off of one of its filaments.
This frame grab from an underwater video shows a vampire squid in a typical feeding position, drifting horizontally in the deep sea with one of its filaments extended.
Vampire Squid Filament
Vampire squid have two filaments, but normally only extend one. This passive scavenging strategy allows the squid to survive in low-oxygen areas of the ocean without expending much energy. Researchers from the Monterey Bay Aquarium Research Institute observed this feeding behavior in the wild and in captive squid.
The vampire squid's filament allows it to collect "marine snow," or floating debris. Squid end up chowing down on a mix of dead crust acean bits, larvae and fecal matter.
