What are ecdosozoa?,
Molting protostomes. They have a cuticle.
What are the phylum of Ecdosozoa?
Nematoda, Nematomorpha, Anthropoda, and Cycliophora
Phyla Nematoda
They are very duverse on terms of habitat. They are parasitic mostly, they have longitudinal muscles and are morphologically simple. Ex) vinegareels
What is the base model nematode?
C. elegans
Why is C. elegans good?
It has good developmental biology mapping and is simple
What are vinegareels? (Nematoda)
They are not really eels, they feed on yeast ad bacteria that causes fermentation.
What are pinworms? (Nematoda
They live in the large intestine and give you itchy anus
