s. Adults have a narrow, pointed snout, upturned eyes, and a light colored stripe on the upper lip. Females can grow to be 6-10 cm and males become 4-7 cm. The call of the Oregon Spotted Frog is a weak series of clucking noises, and is usually only heard during breeding season. Oregon Spotted Frogs are highly aquatic and live in or near permanent bodies of water, including lakes, ponds, slow streams and marshes. They prefer areas with thick algae and vegetation for cover, but may also hide under decaying vegetation. They are most often found in non-woody wetland plant communities (species such as sedges, rushes and grasses). Most Oregon Spotted Frogs hibernate and aestivate. Adults eat insects, mollusks, crustaceans and arachnids. Larvae eat algae and organic debris. Predators include bullfrogs, river otter, raccoons, herons, and garter snakes. The larvae are prey for the larvae of dragonflies, predacious diving beetles, fish and garter snakes. The timing of breeding is related to ice melt on lakes, ponds and marshes. Oregon Spotted Frogs lay their 1,300 eggs in the shallows of a permanent water source. The egg masses protrude above the water surface, which results in egg mortality due to freezing and desiccation. Organism 7: Tailed Frog Scientific Name: Ascaphus truei This frog can be cream, red, gray or black. Adults may have a light streak extending from tip of snout to eyes. The Tailed Frog lives in cold, fast moving streams with cobble stone bottoms. Tailed frogs are mostly aquatic, but adults may emerge during cool, wet conditions to forage on land. Breeding season lasts from May through September, and females deposit their eggs in strings under rocks in fast-moving streams. Habitat loss and modification due to road building and timber harvesting may be contributing to Tailed frog decline. Increased sediment in streams fills in the stream bottoms and reduces habitat for the larvae. Tailed Frogs are found from the ...
