Oceanography – A Model Jellyfish
Jellyfish are beautiful and mysterious ocean creatures. They have no bones, no brain, no heart, and no eyes. They have clear, bag-like bodies that contain their digestive organs and have trailing tentacles that are used to sting and capture prey. About 50% of all jellyfish are bioluminescent. Our biological modeling engineers created bioluminescent jellyfish models (to bring home) and that actually glow in the dark! They were challenged to make their models anatomically correct, but to use their own creativity along the way.
Ask your camper: Why do jellyfish use bioluminescence? (as a defense mechanism to evade predation)
