Join Manatee Lagoon’s Manatee Masters and an expert speaker for a lecture to learn about a new topic each month! Advance registration is recommended, although not required. This helps Manatee Lagoon with tracking the number of visitors we receive and plan for seating.
This month: Kate Galloway is a PhD candidate at FAU studying the mechanical properties of the lionfish venomous spines and how they act in defense and protection. The lecture will focus on the red lionfish, Pterois volitans, which is an invasive species that has 18 venomous spines. Fish spines can have several purposes such as defense, distraction, and using these structures to anchor into crevices. Instead of having hollow spines, lionfish have an anchor-like spine shape with grooves that deliver the venom. This biological shape poses interesting questions of how this shape affects the function or the mechanical properties of the spine, and how well these spines puncture occasional predators like grouper and sharks. In addition to her studies, Kate also makes lionfish jewelry to promote her research. The jewelry will be on display and for sale throughout the lecture.
