The Typical "Jellyfish" Demonstrates Which Stage of the Cnidarian Life

Question

The typical "jellyfish" demonstrates which stage of the cnidarian life cycle?
A) blastula
B) polyp
C) medusa
D) serpentine
E) sessile

Accepted Answer

The medusa stage is the free-swimming, bell-shaped form of cnidarians, which includes jellyfish. The polyp stage is the stationary, cylinder-shaped form, such as seen in coral and anemones. The other choices (blastula, serpentine, sessile) do not relate to the cnidarian life cycle.
