Early Life History Stages of Marine Invertebrates
Many of the feeding structures of juvenile invertebrates function best in adults. How do these structures work in young organisms? How do early life stages of marine invertebrates “make it?”
- As a Research Assistant for Dr. Dianna Padilla I studied feeding in early life stages of the marine, suspension-feeding gastropod, Crepidula fornicata.
- C. fornicata is an excellent study system for these questions because as juveniles they have both a ctenidium for suspension-feeding and a radula for benthic feeding.
- Therefore, we can perform experiments where we manipulate the feeding mechanisms used and examine organismal performance, including growth, survival, metabolic rates, energy assimilation, and morphological features.
Legacy effects
Does the environment experienced be larvae carry-over past metamorphosis and affect juveniles and adults?
