Question

Write the similarities and differences between frogs and toads.

Answer 1

Hint: Frogs are amphibians noted for their ability to hop, croaking sounds, bulging eyes and skin that is slimy. They live all over the world and with more than 6,000 species, are among the world's most abundant creatures.

Complete answer:
Similarities:
1.Their eggs are laid in water by both frogs and toads, but you may be able to tell them apart by the egg arrangement. In general, frog eggs are one mass or cluster, while toad eggs are usually arranged in a chain.

2.Both frogs and toads are markers of a healthy ecosystem. They are sensitive to changes in their environment and can not survive in unhealthy environments, so the presence of frogs or toads is an indication that the ecosystem is safe, whereas a sudden change in their presence can mean that the area has become polluted or is otherwise unbalanced.

3..Another link is that both frogs and toads, while they don't live everywhere are common across the world. Except for Antarctica, frogs live on every continent, while toads live all over the world, except for the polar regions, Australia, Polynesia and Madagascar.

Differences:

Characteristics	Frog	Toad
Eggs	They lay eggs in cluster	They lay eggs in the form of long chains.
Tadpoles	They are slim and gold in color	They are chunky and black in color
Locomotion	They crawl rarely	They move around mostly by crawling
Appearance	They are slender and lean	They are chubby and shorter
Skin texture	Smooth and moist skin	Dry and bumpy
Habitat	Live on water	Live on dry lands
Webbed feet	They have webbed feet to adapt semi-aquatic nature	They do not have webbed feet
Legs	To jump higher and further frogs have long legs	They have short legs and can jump but not as high as frogs
Food	Snails, spiders , insects and small fish	Insects , worms and other invertebrates
Teeth	They have vomerine teeth in upper jaw	They have no teeth
Eyes	They bulge out	They do not bulge out poison glands present behind their eyes.
Parotid glands	Absent	Present

Note: However, as both show characteristics of the other, not all frogs and toads are easy to discern. There are toads, for example, with smooth and moist skin like a frog, and frogs with bumpy, dry skin like a toad. But this is because both of them come under the same vertebrate order, Anura.
