Digestion in Cephalopods includes: 

Digestive gland- absorbs nutrients

Stomach- digestion begins here

Radula-used to scrape away food 

Mouth (beak)- used to take small bites out of food

Caecum-absorbs fluids 

Anus-stool leaves body here 

Intestine- receives food from caecum and absorbs nutrients into the blood

Crop- extension of esophagus for storing food

Cephalopods aren't picky eaters. They eat anything but plants! The only cephalopods that eat plants are snails.

Their food includes crustaceans, fish, bivalves, jellyfish, and even other cephalopods. They are usually carnivores. 

Snails are usually herbivores since they eat plants.

DIGESTIVE GLAND

Cephalopods use absorption and excretion to eat. They capture their food with their tentacles and take small bites. 

Absorption is when the food is captured and transformed into energy. Excretion is when waste is removed from the body and helps the food digest. 

Cephalopods are also discontinuous feeders. They have large meals and store food for later digestion.

Fun Fact: Cephalopods grow very quickly causing the need for protein synthesis to be high.  (When cells make protein)
