How does an octopus make its ink?
Question Date: 2020-03-03
Answer 1:

Good question! Octopi produce ink in a special gland called an ink sac. The "ink" is a combination of dark melanin pigment and a thick mucus the squid harbors in its sac. The intermingling melanin and mucus form a thick ink that can be ejected any time through the octopus's siphon, a structure normally used for jet propulsion. Thanks for your curiosity!
