Exploring Symbiosis
Activity created by Mrs. McAven and adapted from Project Wild
BACKGROUND REVIEW
Elements of any ecological system live in an intricate web of interdependence. When two species of organisms live in close association with each other, their relationship is called “symbiotic”. In a symbiotic relationship, at least one of the organisms directly benefits from its close association with the other organism. There are three major forms of symbiotic relationships: commensalism, mutualism and parasitism.
PROCEDURES You will be given the name of an animal you will
be representing.

TEACHER PRINTOUTS
Goby Fish/Shrimp Mutualism The shrimp digs a burrow into the sand and both organisms live there. Because the shrimp is almost blind, the goby fish will touch the shrimp when a predator is near.
Sea Lamprey/ Lake Trout Parasitism The lamprey uses its suction cup-like mouth to attach itself to the skin of a fish
and bites through the skin. Secretions in the lamprey's mouth prevent the trout's
blood from clotting. Victims typically die from excessive blood loss or infection.
