Today’s post we will see the tailed frogs.
Ascaphus Montanus – Rocky Mountain tailed frog
Description- Frogs are typically either gray or brown with gray, brown or yellow splotches. The Rocky Mountain tailed frog is unique as it has no external ear drum and it has a “tail” which the male frog will use during reproduction. This “tail” ensures successful fertilization in the fast-flowing stream habitat they reside in. Tadpoles in turn have a unique adaptation as well for the fast moving streams. The tadpoles possess large sucking mouth parts which are used to hang onto rocks to prevent from being swept downstream.
Frogs can be found in and along small cold mountain streams. Eggs are laid during late summer and tadpoles can take 1-4 years to metamorphose, depending on water temperature. Males do not vocalize, it has been thought that this was due to females not being able to hear them over the rushing water. These frogs .(1) (2) (3)
Ascaphus truei – Coastal tailed frog
Description- This frog varies in color and typically matches the rocks around the stream inhabited, usually olive, brown, gray or reddish with gray or yellow blotching. The coastal tailed frog males also have a tail which aids in fertilization of the eggs. In order to avoid predators, the coastal tailed frog will jump into the water and tuck in their limbs to allow the water to carry them downstream quickly.
