Put away that garlic, the vampire squid isn’t coming to get you. Our colleagues over at the Monterey Bay Aquarium Research Institute (MBARI) discovered that these cool creatures eat “marine snow”— organic debris that sinks down from the ocean surface into the deep sea. And while their scientific name Vampyroteuthis infernalis literally translates to “vampire squid from hell,” this deep-sea cephalopod actually prefers low-oxygen ocean zones such as the submarine Monterey Canyon. The lack of oxygen in these zones means few predators are able to survive and threaten resident vampire squid. Low-oxygen zones have also been found to foster an abundance of life near the surface, providing a wealth of, er, tasty dead stuff and poop for the vampire squid to feast on. You do you, vampire squid.
Deep-sea squid: elusive, mysterious and parental? While some squid in the open ocean release their eggs to drift in the water column, our research partners at the Monterey Bay Aquarium Research Institute have discovered a deep-sea squid (Bathyteuthis berryi) that broods her eggs in a sheet attached to her body! It’s the second known instance of parental care in squid. Watch MBARI’s latest video for some amazing footage!
“I vant too dreenk your… no, not blood! Ew!” Despite their name, vampire squid eat marine snow—organic particles the drift down into the deep sea. Yum. 🌨️
We know that and much more thanks to the research and technical breakthroughs of our partners at the Monterey Bay Aquarium Research Institute! Learn more about how technology helps them study the deep sea.
The sort-of gross diet of the “vampire squid from hell”
Our colleagues at MBARI – the Monterey Bay Aquarium Research Institute – have been sharing videos and stories about the vampire squid for years. We in turn have been sharing them with visitors during our daily Mysteries of the Deep auditorium program.
Now MBARI researchers have solved the mystery of what these unusual deep-sea animals eat. It’s a fascinating tale, with a high gross-out factor – if you’re easily grossed out by animals that eat corpses, feces and mucus.
Turns out that the vampire squid, an ancient animal with characteristics of both squids and octopus, lives in a low-oxygen zone where living prey is scarce. But there’s an abundance of marine snow raining down, consisting largely of poop, dead bodies and mucus discarded by other ocean life.
So, unlike all other known cephalopod species, it hangs out, waiting for this manna to sink down, where it traps the goodies on filament-like tentacles, wraps them in mucus and gobbles it up.
This despite a Latin name (Vampyroteuthis infernalis) that translates as “vampire squid from hell.”
You’ll find much more in the video, on the MBARI website, and in this article from Discovery News.
Not as charming as the cast of Twilight, perhaps. But a mystery of the deep – solved.
