Phylum Frenzy
This phylum includes animals with no tissues and only cellular organization.
What is Porifera
This structure in molluscs secretes the shell.
What is the mantle
This phylum has organisms with pentamerous radial symmetry as adults.
What is Echinodermata
This scraping, tongue‑like structure is used by many molluscs to feed.
What is the radula
An organism that lives on or near the seafloor is described as this.
What is benthic
Jellyfish and sea anemones belong to this stinging phylum.
What is Cnidaria
Cephalopods shell has been reduced to this structure.
What is a pen
This phylum is the only major animal group with no symmetry at all.
What is Porifera
Animals that eat food that settles on the ocean floor are this type of feeder
What are deposit feeders
The three major body segments of arthropods are these
What are head, thorax, and abdomen
(must get all 3 for points)
Sand dollars, sea stars, and sea cucumbers are members of this phylum.
What is Echinodermata
Cnidarians use this specialized stinging cell to capture prey.
What are nematocysts
Jellyfish exhibit this type of symmetry.
What is Radial Symmetry
Animals that filter particles floating in the water are this type of feeder.
What are suspension feeders
(filter feeders are a type of suspension feeders)
Hemichordates form an evolutionary bridge between these two phyla
What are Echinodermata & Chordata
(must get both for points)
This phylum is known for jointed legs and segmented bodies.
What is Arthropoda
Echinoderms move using these water-filled structures.
What are tube feet
Molluscs and arthropods share this type of symmetry
What is Bilateral Symmetry
Sponges use this method to get food from the water around them.
What is filter feeding
Arthropods must do this in order to grow.
What is molt
Lancelets and tunicates belong to this phylum.
What is Chordata
Sponges rely on these structures made of silica or calcium for support.
What are spicules
The larval stage of echinoderms has this type of symmetry.
What is Bilateral Symmetry
Sponges feed using these cells that create water flow.
What are collar cells
Unlike jellyfish, these cnidarians spend their entire life in the polyp stage and can form massive reef structures
What is coral
