📖 1. Overview
The colossal squid is a giant squid living in the deep waters around the Southern Ocean and is considered the largest known invertebrate.
🦴 2. Anatomy & Morphology
Its eyes reach up to 30 cm in diameter, possibly the largest in the animal kingdom, and it has the largest beak of any squid along with 25 rotating hooks arranged in two rows at the tips of its tentacles.
🔍 3. Ecology & Behavior
It appears to be an ambush predator that eats large fish such as large toothfish as well as other squids. Because of its huge body, it is thought to need little food and live at a slow pace. Adult beaks have been found inside sperm whale stomachs, showing that adults reach great depths.
🇰🇷 4. Connection to Korea
No direct record connecting this species to Korea has been found.
