Marine Biology exploration of Cephalopods
Work through all the tasks of this assignment in order. The goal is to understand what a cephalopod is, and hopefully realize how surprisingly advanced cephalopods are, especially for something that is not even a vertebrate animal. Each section has a resource and questions to answer based on the resource. Remember to read and answer carefully, questions are marked right or wrong.

What does cephalopod literally mean in Greek?
tentacle
head-feet
octopus
mollusc
The four types of cephalopods that are extant (means still around, not extinct) are
belemnites
octopus
nautilus
cuttlefish
squid
ammonites
The main difference between the two big groupings of cephalopods-the Coleoidea and the Nautiloidea-is
have tentacles or not
live in fresh or saltwater
have an external shell or not
Scroll down to the Biology section. Cephalopods have a brain and nervous system that is considered
the biggest and most developed of any invertebrate animal
the biggest and most developed of any animal
similar in size and development to its relatives the snails
The sense for cephalopods that is most highly developed is
vision
hearing
taste
smell
Scroll several pages down to the section labeled "Feeding". Click the 3 parts that are important structures that help cephalopods feed.
radula
strong jaws
fangs
flat grinding teeth
two-part beak
toxic saliva
Your last task for this assignment can be done by yourself or with one partner. You must create an infographic mini-poster (one piece or two connected pieces of plain copy paper) about one of the cephalopods that is listed below.
Include a hand drawn picture of your cephalopod, the common name, the scientific name (included in the list), where in the world they are found, what habitat in the ocean are they found in (like around reefs, deep sea, swimming in the open ocean, solitary, or in schools, etc.), what they eat, if they are important to humans (skip this if they are not important to humans). Lastly, find some interesting facts about your cephalopod and really make sure that your message is about how cool they are. Hint: try to find a drawing of your cephalopod in Google images, rather than a photograph. It is easier to draw from a drawing than trying to copy from a photograph. Some cephalopods might not have a drawn image available in Google images, but if you can find one, that will be an easier model to copy as you draw onto your poster.
Use the sign-up sheet linked in the module for this task in Canvas. See the Canvas module for a model of a cephalopod poster to get layout ideas.
