Earlier this month, scientist examined what they believe to be just the second ever fully intact Colossal squid. The female squid weighs 770 pounds and has been frozen for eight months near Antarctica.

Its eight arms are each more than three feet in length. Its two tentacles would have been perhaps double that length if they hadn’t been damaged, scientists said.

“This is essentially an intact specimen, which is almost an unparalleled opportunity for us to examine. This is a spectacular opportunity,” Kat Boulstad said in an interview with the Wall Street Journal.

Scientist are hoping to find out more about where the creature fits in the food chain and basic facts about how the colossal squid lives and dies.
