Dear Dr. Wood I searched your FAQ pages, but couldn't find the answer to your question, so perhaps you could tell me: How do you tell the difference between a squid and a cuttlefish? Thanks, Dr. Ian Chai |
| Answer: |
| In general terms, squid tend to be more streamlined as most of them live well away from the shore, while most cuttlefish live near the shore and in association with the bottom. Cuttlefish tend to be broader and less streamlined. Squid have a pen (very thin shell remnant) for support while most cuttlefish have a thicker internal "shell" - the cuttlebone used by many to supply Calcium to birds. Dr. James Wood |
