Hemoglobin is an iron-based pigment, so it gives the blood a red color. Squids are a little different. Instead of hemoglobin, they have a pigment called hemocyanin that binds to oxygen in the blood. Hemocyanin is a copper-based pigment, so it gives squid blood a blue color.

This suggests that if it feels pain, rather than being able to pinpoint the location of a wound, an injured squid may hurt all over.

Why is squid sperm so big?

Lab studies also reveal that, despite their size, small squid make bigger sperm than large squid. That's not because the bigger sperm outcompete the smaller ones; instead, they're large because they have to withstand the harsh environment outside of a female's body.
