What is a mass of frog eggs called?
Frog eggs floating in a pond: these clusters of floating eggs are called “egg masses”. Frogs lay up to 4,000 eggs at one time! Tadpoles hatch from the eggs and live in the pond. The Froglet’s tail shrinks, the lungs develop and the back legs grow and then we have a Frog.

How do wood frogs survive being frozen?
During the wood frog’s hibernation, cryoprotectants inside of the frogs’ bodies, act like antifreeze, preventing ice crystals from forming inside their cells by lowering the body’s freezing point keeping their cells and tissues from freezing and bursting.

What does a frog egg mass look like?
Green egg masses floating at the water surface might easily be mistaken for clumps of algae. Wood frog larvae are dark brown to blackish tadpoles. Immediately after hatching the tadpoles are black, about .25″ long and found on or near the egg mass.
What do wood frog larvae look like?
Wood frog larvae are dark brown to blackish tadpoles. Immediately after hatching the tadpoles are black, about .25″ long and found on or near the egg mass. They remain with the egg mass for a few days grazing on the symbiotic algae before swimming throughout the pool.
What do wood frog eggs look like underwater?
