Archie the giant squid is an 8.62 meter long, preserved female giant squid in the London Natural History Museum Spirit Collection, as a display and as a specimen. Her name "Archie" is short for Architeuthis dux, the Latin name for the giant squid. She is not considered fully grown, as giant squid can grow up to 13 or 14 meters long. She has 8 shorter arms covered with serrated suction cups and 2 longer feeding tentacles. When attempting to weigh her, Archie broke the museum's scales, so her weight is estimated somewhere upwards of 200 kg. Archie is held in a custom acrylic 9-meter transparent tank filled with a 10% solution of formol-saline, which is a mix between salt water and formolin. She is the biggest fluid-preserved specimen at the museum.
