Cephalopod Lateral Funnel Adductor

Cephalopoda Glossary


 

Several sepioid families have a superficial lateral funnel adductor muscle (figure below) that supports the attachment of the funnel to the head. In ommastrephid squids the dorsal funnel adductor muscles have one muscle bundle that has migrated during evolution to a similar lateral position. These latter muscles are attached anteriorly to the cephalic cartilage while the lateral funnel adductors attach to the head musculature. In addition, some cranchiid squids have an attachment somewhat similar to the sepioid one. For the purposes of keys, these three types are not distinguished.
