Curator of Mollusks Liz Shea, Ph.D. has been working hard on new exhibits for the Delaware Museum of Nature and Science, including Diel Vertical Migration and Submersible Interactive exhibits. Diel Vertical Migration is a form of migration when organisms move to the uppermost layer of the sea during the night, and swim back to the bottom during daylight. Though mostly unseen, Diel Vertical Migration is one of the greatest migrations in the world, in terms of biomass.
In order to portray the fascinating underwater migration these mollusks undergo, one of a kind displays are created for each specimen. Lucy and Hannah joined Liz in the lab to collect photos and measurements for the new displays.
We learned that a lot of the organisms that participate in Diel Vertical Migration exhibit bioluminescence, the production and emission of light by a living organism. These animals live in the deep, dark depths of the ocean, and their bioluminescence allows them to find and lure prey, while also warding off predators. In the lab, we photographed and studied these fascinating mollusks and fish up close. Liz taught us about these unique animals as we prepared them for their photos. We cannot wait to see these fascinating animals on display in the new Museum!
