Travel to the Woods Hole Oceanographic Institute in Massachusetts, where scientists study the microscopic world of the pteropod, more commonly know as the sea butterfly.
Nicknamed for the way it swims through the water, the sea butterfly propels itself with fins that protrude from its transparent shell and flap like a butterfly’s wings.
Though no larger than a grain of sand, these otherworldly creatures are a staple in the diet of marine animals like the sea angel. But the sea butterfly–and the predators that call it dinner–is in danger from the changing chemistry of our warming oceans. Ocean acidification dissolves the pteropod’s shell, often killing the animal.
Join Ari Daniel Shapiro as he delves into the delicate ecosystem of the sea butterfly.
Strategies for Using EOL Podcasts in a Variety of Learning Environments
- Have students write down terms they are unfamiliar with while listening to the podcast. After listening to the podcast, discuss and define them as a group.
- Have students close their eyes and visualize what is being discussed in the podcast. Then have them produce a sketch based on their interpretations.
- Have students preview several Encyclopedia of Life podcasts and choose the one they find most interesting. Ask students to research the species or species group and present to their peers.
