What is the difference between a frog and a toad?

. . . . . . . . . . . . . . . . . .

Frogs and toads might look similar at first, but these croaking cousins are not quite the same. Frogs are the splashy stars of ponds and lakes, while toads prefer life on land. And both are built to suit their homes. Frogs have slim bodies and long, powerful legs made for giant jumps and strong swimming. They have smooth, wet skin, which is often green, brown or grey – colours that help them blend in with their watery surroundings. Toads are stumpier and chunkier, with shorter legs, better suited for crawling than hopping. They have dry, bumpy skin, which is usually brown or grey, to help them disappear among rocks, soil and fallen leaves.

Webbed feet for pushing through water

Frogs are rarely found far from water.

WACKY FACT

Frogs and toads use their ultra-soft, super-sticky, extra-stretchy tongues to snatch insects mid-air before slurping them back for a wriggly snack.

Short back legs for crawling

Chunky, squat body with broad face

Bumpy, dry skin

Toads often wander far from water, returning only to lay eggs.

Frogs and toads both lay their eggs in water.

Toads lay their eggs in long, winding strings. Frogs’ eggs are blobby and jelly-like.

WACKY FACT

The footprints that astronauts have left on the Moon could last for millions of years because there is no wind to blow them away.

When scientists first looked through a telescope at the Moon, they thought the dark patches on its surface were oceans, so they named them maria – which means ‘sea’. They later realised there was no liquid water on the Moon!

This is the Sea of Tranquility, one of the Moon’s biggest maria. It is where humans first landed on the Moon.

What are the dark patches on the Moon?

The Moon shines bright and silvery-white in the night sky. But if you look closely, you might spot dark splotches on its surface. These patches formed billions of years ago when… WHAM! KABAM! Giant rocks that were shooting through space crashed straight into the Moon. They left behind huge holes in the Moon’s surface. Super-hot, melted rock bubbled up from beneath the Moon’s surface and filled these holes. When it cooled, the melted rock turned solid, creating smooth, dark patches.

Most of the Moon’s surface is covered in pale grey dust, which shines bright white in the sun.
