We just learned about the Cephalopod Funnel.
Another part of a cephalopod is the Ink Sac.
This is inside the mantle where the gills are, and when an octopus or squid gets scared it will let out some black ink to hide, and to try and scare off anyone coming to attack it.
The ink just comes out of the ink sac, and they use the funnel that they squirt water out of to shoot the ink all over the place.
The ink is so dark that sometimes people use it to color types of food very dark.
