Order:  Anura

    Even though we thought frogs and toads were the same, we found out they weren't.  We compared them here:

Toad

Frogs Toads
Family:  Ranidae Family:  Bufonidae

What they look like:  Smooth, green or brown skin with dark markings.  Pointed heads.  Back legs are longer than front ones. About 1-4 inches long.  Cold-blooded.

What they look like:  Beige skin with brown markings.  Dry and warty looking skin.  Chubby.  About 3 inches long and weigh about 3 ounces [males].  Females are bigger. Cold-blooded.

Where they live:  All over the world except for Greenland, Antarctica, Madagascar, New Zealand, and Australia.

Where they live:  Most of Europe, Asia, and northern Africa

What kind of area: Live in water [pools and streams.]  Some live in rainforests.  They need to keep their skin wet, so they don't go far from water.

What kind of area:  Live on land--in woods, fields, gardens

When they are active:  Day and night.

When they are active:  Nocturnal.  Sleep during the day and hunt at night.

What they eat:  Carnivorous.  Eat fish, small mammals, other amphibians, and insects.

What they eat: Carnivorous.  Spiders, ants, earthworms, slugs, caterpillars, beetles, and bees.  Also frogs, newts, and lizards.

Enemies: Snakes and birds.  People would also be enemies because we are destroying the wetlands they need.

Enemies:  Birds of prey and snakes.  Toad has poisonous skin so enemies are careful with them.

How they live:  Mostly alone.

How they live:  Mostly live alone except for hibernating and mating times.

Hibernation:  The frogs that live in colder climates hibernate.  Some dig holes or find cracks in logs or rock areas.  Their heart beats and breathing slow down and their body temperature reaches close to the outside temperature.  They have a lot of glucose in their bodies and it keeps them from freezing.  Half-frozen frogs will thaw out and live.  Some frogs hibernate under water.  These don't breathe and get their oxygen from the water through their skin.

Hibernation:  Will hibernate with other toads in winter.  Hibernation begins in October when they find a safe, underground place to stay.  They live on body fat that they stored in their bodies during the fall.  Some toads have hibernated for as long as three years.

Estivation: They dig a hole in the soil to get away from bad weather conditions like drought or high heat.  They sleep through this bad time.  Sometimes frogs will shed a layer of skin, wrap it around themselves for more protection, and wait for rain.

Estivation:  Some toads dig a burrow in the ground in order to escape dry, hot weather.  They might put stuff like gel all around their burrow so that they lose less water.  They estivate for 8-9 months until the rains begin again.

Mating:  Lay their eggs in water.  Eggs are fertilized and become tadpoles and then become adult frogs. 

Mating: They mate from February-April, when hibernation is over.  Females lay eggs in ponds and the males fertilize them.  The eggs that develop become tadpoles.  It takes 12 weeks for the tadpole to become a toad. 

How long they live:  10 years.

How long they live:  30-40 years

Cool Frog Fact:

When metamorphis happens [changing from a tadpole to an adult frog], the tadpole's tale shrinks back inside the frog's body.

Cool Toad Fact:

  To swallow food, they draw their eyeballs into their head to help push the food down.  Y U C K Y Cool.
