A benthic, sessile organism that is typically found in shallow waters
What are, Sponges
Jellyfish, coral, hydras, and sea anemones are all included in this phylum

What is, the intestine.
The process in which an animal turns from the larva stage into into adult stage.
What is, Metamorphosis.
A sponge has a lot of tiny little openings called ___________
What are, pores.

What is, the gizzard
A type of reproduction used by sponges where the sponge will spawn with no particular target in mind

Jelly fish can be found in two different body types. Those body types are
What are, polyps and medusa
The phylum contain flatworms
What is, platyhelminthes
A threadlike structure that runs along the entirety of the worm, underneath the organs
What is, the ventral nerve cord.
Sponges are able to produce sharp structures called ____________ that are used for self defense
What are, spicules
Contrast the processes of budding and fragmentation
What is, budding involves a new organism growing as an outgrowth or "bud" from the parent organism, which later detaches. Fragmentation, is when the parent organism breaks into multiple pieces, and each piece grows into a new, independent individual
A special type of stinging cell found in Cnidarians that can act as self defense, or can be used for capturing prey
What are, nematocysts.
A type of parasitic worm that attaches itself to the intestinal wall of vertebrates
What is, a tapeworm
A smooth section with no segmentation that is involved in the organisms reproduction
What is, the clitellum.
A type of feeding in which organisms eat sediment and digests the organic matter as it passes through their intestine
What is, Deposit feeding.
The type of cell responsible for delivering food to all of the cells within the sponge
What is, an amebocyte.
Describe the digestive process of cnidarians
What is, One mouth that takes in food, where it is then taken to the gut to digest, and then released through the mouth.
A type of worm that lives in deep water hydrothermal vents. They have retractable bodies
What is, a tubeworm
A fleshy bump located over the mouth of the earthwrom
What is, the prostomium
