Pathikrit Bhattacharyya (aka Po), from Casey Dunn’s Invertebrate Zoology (Biol 0410) course at Brown University, tells the story of how the lancet liver fluke gets through life.
Karen Connolly, from Casey Dunn’s Invertebrate Zoology (Biol 0410) course at Brown University, tells the story of how echinoderms (starfish, sea urchins, and their relatives) can change the stiffness of their skin at will.
Stephanie Yin, from Casey Dunn’s Invertebrate Zoology (Biol 0410) course at Brown University, tells the story of a parasitic barnacle with a fascinating lifecycle.
Katherine Hadley and Jonathan Leibovic, from Casey Dunn’s Invertebrate Zoology (Biol 0410) course at Brown University, sing a song about tardigrades. They composed the song, performed it with friends, and made the animation.

Rebecca Haumann describes how some plants deal with drought by completely drying out.
This is the first in a series of episodes made as final projects in classes at Brown University in the fall of 2011. The classes were Plant Diversity (Biology 0430), taught by Erika Edwards, and Invertebrate Zoology (Biology 0410), taught by me.

Symbion pandora is a microscopic animal that lives exclusively on the mouth-parts of lobsters. When we think of a life-cycle, we usually think of a baby growing into an adult, a female mating with a male, and then the female giving birth to a baby. But as Symbion pandora demonstrates, this isn’t always the case. Symbion pandora undergoes both asexual and sexual reproduction. Its life cycle is especially interesting because the timing of its sexual reproduction matches the moulting of its lobster host. This allows Symbion pandora to move from the lobster’s old shell to its new one, a remarkable solution to the problem of a temporary home. First described in 1995 by Peter Funch and Reinhardt Kristensen, Symbion pandora’s life-cycle provides insight on the incredible diversity and range in the ways organisms grow and reproduce.
