small waist
no neck
broad, flat skull

- streamlined body shape for swimming - no movement of head is beneficial during swimming - easier to swim through water; holds prey


thin and moist

- allows for gaseous exchange (cutaneous respiration) - allows for water exchange (osmosis)

front legs and feet

short, with 5 toes

- used to keep the front part of the body off the bottom or ground

hind legs and feet

long, powerful, with 5 toes

- able to jump great distances, and change direction quickly - webbed toes aid in swimming


upper body green with many spots
light under belly

upper body green with many spots - it conceals the frog in its natural habitat; it also forms a disruptive colour pattern which tends to obscure the shape of the frog light under belly - where there is normally a shadow, it reduces the appearance of solidity or mass when viewed from the side or underneath


positioned on top of head
lower eyelid transparent
large and bulging

positioned on top of head - it gives the frog a wide angled visual field; allows frog to remain in water with only part of head exposed lower eyelid transparent - able to see under water large and bulging - aid in swallowing; - detect movement and velocity of an object


a flat disk-like tympanic membrane

- streamlines the body, prevents water from entering ear canal


very large and broad

- able to catch and eat large prey


attached at front of mouth
long and sticky

attached at front of mouth - enables it to be flicked out quickly long and sticky - prey sticks to it when caught


laid in masses
gelatinous covering

laid in masses - eggs on the outside protect the eggs on the inside sticky - adhere to plants, so they are not carried away coated in gelatinous covering - protection from mechanical injury, infections and disease, and dehydration; - it conserves heat produced by metabolism of the embryo
