DESCRIPTION
Throughout our second semester, each student in our Marine Bio class updates a field guide based on each new phylum that we cover. This website update will cover the third phylum of invertebrates we covered in class, Mollusca. Each page of our field guide has to include the phylum name and an example of a creature from that phylum, including the creature's common name, scientific name, and three interesting facts about them. We also needed to include a to-scale drawing of the creature with stippling to show it's shade variation.
CONTENT
In my field guide for the phylum Mollusca, I drew a garden snail. It's scientific name is Cornu aspersum.
They live for about 5 years in the wild.
They can sleep for three years.
They secrete mucus to protect their bodies.
An image of this page of my field guide is included below.
Animals in the phylum Mollusca have bilateral symmetry and have no segmentation. They have an exoskeleton and a complete digestive tract. Cephalopods have a complex nervous system while bivalves' are simple. They use gills for respiration. They have a mantle, foot, siphon, and a radula. They are important food for humans and other sea creatures and can be predators, benthic, or parasitic in their natural environment.
REFLECTION
I like that we are able to draw any animal from the phylum and that gives us freedom to include different species than our classmates. I find that it takes a long time to scale a drawing and to get the right shape on a square grid, but it seems to become easier with practice. I like that we don't need to include all information from the unit on the page because it would make organization more difficult. Using the designated amount of time in class has been a challenge, but I am able to complete the assignment without too much difficulty otherwise.
