Symbiosis, behavior and adaptive coloration in marine decapod Crustacea
Decapods are among the best-known crustaceans, ranging from tiny shrimp to crabs with a leg span of up to nearly 4 m. Major predators, disturbers of sediments, and elements of food chains, these animals are found in almost all marine habitats. New species continue to be found. Of those already known to science, often the descriptions are very old and lack details needed for more modern comparative work. Genetic studies are in their infancy. My graduate students currently are studying the ecology of decapods and other crustaceans along the poorly-studied Texas coast.
Dr. Wicksten and her students have been active in studying the biota of local marshes, beaches and springs. Despite their abundance, some of these common shrimps and other crustaceans largely have been ignored and their contributions to local ecosystems remain largely unstudied. Using genetic studies, we have determined that some of these species in fact are species complexes, or their supposed relationships to others are not supported. Some of these species could be endangered; others harbor parasites that can be passed to wading birds.
New remotely operated vehicles can operate at depths of 4000 m or more and transmit live video feed and high resolution still photos directly from the sea floor to my office. These images show animals previously known only from broken bleached dead specimens as living animals in their natural habitat. I cooperate in identifying these crustaceans as best as possible in the absence of specimens. I have been able to correlate “morphospecies” with particular host corals or sponges. I am working on new syntheses on biogeography of decapods at 700-4400 m, host specificity and behavior. With thousands of available photographs from the Gulf of Mexico and Pacific, I am happy to accommodate undergraduate and graduate students looking for projects.
