Invertebrates
Flatworms
Bilateral symmetry, three tissue layers

Larval stages of Anisakis are found in fish and can be passed to humans if raw (or undercooked) fish is consumed.
Arrow Worms
Transparent, streamlined body with fish-like fins and tail
Voracious predators; they swim in rapid, darting movements to capture prey (small planktonic crustaceans, fish larvae, and other plankton).
Segmented Worms
Body cavity is a coelom, which is lined with tissue derived from mesoderm, as in higher animals.
-
Bryozoans
Bryozoans (together with phoronids and brachiopods) possess a unique feeding structure called a lophophore, ciliated tentacles surrounding the mouth
Some are encrusting, others form small fan- or tree-shaped colonies.
Suspension feeders
Phoronids

Worm-like, living in tubes of sand grains
