Explore the World of Slimy Sea Creatures


Invertebrates like octopuses, jellyfish and squid have fascinating adaptations for life in their ocean ecosystems. Take on the role of marine biologist as you learn about how slimy sea creatures survive and thrive.

Students will observe sea stars, sand dollars and moon snails, to name a few. They will watch a squid dissection while learning about anatomical structures of invertebrates. We will investigate the secret of how octopuses change color and how pearls are made. Students will also consider what kind of invertebrate they would like to be. They will test their knowledge by playing a game that rewards those with the best mastery of vocabulary from the class. Each student will create artwork using seashells and other materials from Mother Earth. Slimy Sea Creatures offers a great way to inspire students to pursue further studies in marine biology.
