make its own food.
- Infects about 50 million people worldwide

- Unicellular
Chondrocladia lyra
- Found in the deep sea, attached to the bottom
- Has Velcro-like barbed hooks that cover its limbs and catch prey as it
is carried by on the current
- Also feeds by pushing water through its ostia
- Is multicellular, but does not have tissues, organs, or organ systems
Leucaltis clathria

- Is sessile and attaches to either the sandy bottom or rocks.
- Has a skeleton of spicules
- Found in the Caribbean Sea
Stichodactyla haddoni
- Is a multicellular carnivore
- Uses nematocysts to stun and capture their food
- While closed up, they exhibit radial symmetry
- They can not swim and are sessile in their adult lives
Cassiopea xamachana
- Is a multicellular carnivore
- Uses nematocysts to stun and capture their food
- While closed up, they exhibit radial symmetry
- They swim, but like to remain upside down on the bottom of the
ocean floor
Mnemiopsis leidyi
- Is a multicellular carnivore
- Uses cilia to move in the water and create a reflective rainbow light

- Has two mobile tentacles
- Is found in the Mediterranean Sea
- Has bilateral symmetry, a central nervous system, and tissues
organized into organs
Tevnia jerichonana

catching prey
- Is found in the deep ocean
- Has bilateral symmetry, a central nervous system, and tissues organized into
organs

Eucidaris tribuloides
- Looks identical to a developing human for the first four days after
fertilization.
- Has large, wide spines that it uses for locomotion
- Has a mouth with five teeth on its underside, giving it pentamerous
radial symmetry.
Pseudocolochirus axilogus
- Brightly colored, toxic multicellular predator.
- Filter feeders that use their tentacles to feed on prey

five equal parts
- Can be found in the Pacific Ocean along Australia

notochord.
