Today we discussed some of the key features of each one of the extant groups of cephalopods. Then we proceeded to discuss some of the most important features of cephalopods as a whole and their variation across different groups. We discussed:
- Shell evolution - Presence/absence, location, material, function
- Feeding - Beak and radula
- Locomotion - Crawling and swimming. Using fins and using siphons for jetting
- Nervous system and complex behavior
- Reproduction and development
