Cnidarian Life Cycle at Life

Cnidarian Life Cycle. Cnidarian life cycles life cycles of cnidarians can be complex, but in general life begins in the form of a larva called a planula. To investigate the evolution of cnidarian life cycles, data from the small subunit of the ribosome are used to derive a phylogenetic hypothesis for medusozoa.

Cnidarians have two distinct body plans, the medusa (a) and the polyp (b). However, molecular data can be a useful tool to elucidate medusozoan life cycles by tying together different life history stages. Cnidarians have separate sexes and many have a lifecycle that involves two distinct morphological forms—medusoid and polypoid—at various stages in their life cycles.

Cnidarians

Another part of their life cycle includes the sexual or medusa stage. Cnidarian life cycles life cycles of cnidarians can be complex, but in general life begins in the form of a larva called a planula. In fact, an attribute of the entire class anthozoa is the absence of a medusa. All stages of clytia’s life cycle can be reproduced under laboratory conditions;
