Study Notes
Toad Life Cycle
- Toads undergo metamorphosis, a complete change in form during development.
- Unlike humans, toads don't gradually change; they transform through distinct stages.
- Toads begin life as eggs.
Stage 1: Egg
- Toad eggs are enclosed in a jelly-like substance.
- Eggs are laid in streams or ponds.
- Eggs may number in the hundreds or thousands.
- Inside the egg, a tiny embryo develops.
- Not all toad eggs survive.
Stage 2 & 3: Tadpole & Toadlet
-
Newly hatched toads are called tadpoles or pollywogs.*
-
Tadpoles have tails and gills, requiring water for breathing.
-
They have special jaws for eating algae, a food source for growth.
-
Toadlets develop legs and start resembling toads (Think teen years)
-
Toadlets have sticky tongues for catching prey.
-
Toadlets develop lungs, enabling breathing air.
-
Toadlets still need water frequently to avoid dehydration.
Stage 4: Toad
- Adult toads have developed two front and two back legs for jumping.
- Tails are completely absorbed.
- Lungs are fully developed for air breathing.
- Toads are capable of reproduction.
- Mating season typically occurs after summer rains.
- Mature female toads reproduce around age three; males around age two.
- Male toads make loud calls to attract females.
