Bioluminescent octopus squid attacks underwater cameras in the deep sea, shedding light on their hunting habits

In the deep sea, a rare species of squid known for its glowing bioluminescence was recorded attacking underwater cameras. The research team from the Minderoo Association and the University of Western Australia (UWA) Deep Sea Research Center captured the encounter at a depth of 1,000 meters below the surface of the Pacific Ocean. The team used a camera attached to a floating decoy in the waters near the Samoa Strait, which flows through northern Samoa.

During this research expedition, experts discovered Dana octopus squid, a member of the Octopoteuthidae family that specializes in feeding on marine fish, crustaceans, and other squid species. These squids have eight arms and can grow to impressive sizes. Dana octopus squid in particular can be up to 75 centimeters long and use its luminescent body to emit light through photophores located at the tips of its arms. This bioluminescence helps them paralyze their prey and communicate with others in the dark depths of the ocean.

While attacking underwater cameras, Dana displayed its unique bioluminescent abilities, potentially using them to scare prey. This behavior sheds light on little-known habits of Dana octopus squids as live encounters with these creatures are rare. Most observations come from stranded specimens or bycatch. Researchers believe that bioluminescence plays an important role in their hunting strategies and communication in these deep sea environments.

In conclusion, this surprise attack by an octopus using an underwater camera has provided valuable insights into how these creatures use their huge bioluminescent organs to catch prey. Further studies on this rare species can help us understand more about their adaptations to life in extreme environments like the deep sea.
