A research team from the Oceanographic Foundation has created a deep-sea platform fitted with a camera designed to document squid prey in the dark depths. The work is described in a peer‑reviewed article in Deep Sea Research.
To avoid startling the giant squid, whose eyes sense short wavelength blue light, the researchers used long wavelength red light. This spectrum is less visible to the squid, allowing the crew to observe the animals on video without causing disturbance.
On the platform, the scientists added a lure: a simulated jellyfish that carries blue‑flashing lights designed to mimic bioluminescence and attract the squid into view.
From depths ranging roughly from 557 to 950 meters in the Gulf of Mexico and near the Exuma Strait by the Bahamas, the team recorded several encounters with large squid in their natural habitat.
Prior to any strike, the squid trailed the platform for about six minutes. Then it seized the fake jellyfish. The observations challenge prior assumptions that giant squid ambush prey; instead, the animal appeared to be an active predator, pursuing a target rather than waiting for an opportunity.
Researchers plan to continue investigating squid behavior, expanding observations of hunting strategies, range use, and responses to targeted stimuli as part of ongoing deep-sea ecology studies.
