Molecules Clarify a Cnidarian Life Cycle – The ‘‘Hydrozoan’ ’ Microhydrula limopsicola Is an Early Life
Background: Life cycles of medusozoan cnidarians vary widely, and have been difficult to document, especially in the most recently proposed class Staurozoa. However, molecular data can be a useful tool to elucidate medusozoan life cycles by tying together different life history stages. Methodology/P...
