Marine researchers had a strange encounter during a recent dive in California’s Monterey Bay. A squid mom hauled a spawling sheet of eggs through the water.
“During a recent deep-sea dive, MBARI researchers encountered this incredibly rare sight — a deep-sea squid (Bathyteuthis sp.) grasping hundreds of eggs in her arms,” the Monterey Bay Aquarium Research Institute (MBARI)
Squids are generally
Parental instinct gives the best answer for this behavior, Stephanie Bush, a marine scientist at the Smithsonian National Museum of Natural History, told Mashable. “The squid is protecting the eggs against predators,” Bush, who was not part of the dive, said. This squid could have perceived the noisy robotic vehicle as a threat, and promptly fled with the eggs when the vehicle traveled close by.
Since squids live in the deep oceans, we tend to think of them as fairly slow-moving (to conserve energy in nutritionally-limited dark waters,
“The squid is protecting the eggs against predators.”
There is also a secondary reason for this peculiar behavior, Bush added. Water temperature is crucial for egg development, and the temperature varies at different depths in the oceans. So female squids sometimes carry their eggs to ensure they’re exposed to optimal temperatures.
Marine biologists call this “brooding,” wherein mothers watch over their eggs until they hatch. Only a handful of known squid species carry eggs along with them. Female squids are
