w/ extra / deformed hind legs dead museum specimens
Pacific Tree Frog with extra/ deformed hind legs - museum specimen from Pieter Johnson's groundbreaking study at Stanford University. The frogs' malformed limbs are caused by the infestation of tiny parasitic flatworms during their tadpole stage. The Pacific Tree Frog is able to adapt to a wide variety of different habitats - from wet rainforests in the coastal ranges of the Pacific Northwest to dry, cold high altitude Ponderosa Pine forests east of the Cascade Mountiains.
