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 first phylum of invertebrates we covered in class, Cnidaria. 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 Cnidaria, I drew a Lagoon Jelly. It's scientific name is Mastigias papua.
These jellies live in shallow waters.
They live in symbiosis with zooxanthellae.
It has no cnidocyte cells.
An image of this page of my field guide is included below.
Animals in the phylum Cnidaria have radial symmetry and have no segmentation. Their skeleton is hydrostatic and they have an incomplete digestive tract. These animals have nerve cells and use their body surface for respiration. They have nematocysts. They are important for tourism and fishing and are solitary 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.
