What are two adaptations of fish that allowed for movement on land?

Answer 1

Frogs have strong legs to help them jump/hop around, and they blend in easily with marshes and grasses.

Wrong^

a frog has very powerful sperm cells

both of you r wrong i got this from class so this is right^v

strong skeletons and muscular limbs adapted for moving on land(:x3

Answer 2

Adaption Skin- Apart from camouflage, the American Bullfrog has paratoid glands on the surface of their skin, when it feels threatened to predators; it will release a toxin that could potentially kill the animal. Childhood Tadpoles can live up to two years before turning into frogs. The longer they remain a tadpole, the bigger the frog will be. Tadpoles eat algae, plant tissue, and aquatic insects. The tadpoles are also protected because they taste bad. During the tadpole stage, most of them respires external or internal gills. They do not usually have arms or legs, and have fin-like appendages and a tail, similar to most fish. As a tadpole matures, it commonly metamorphosizes by growing limbs and then absorbing its tail. Lungs develop around the time of leg development. During the final stages of external metamorphosis, the tadpole's mouth changes from a small, enclosed mouth at the front of the head to a large mouth the same width as the head. The intestines shorten to make way for the new diet. Friend Other frogs Enemy The snakes Special The American Bullfrog has a body about five to eight inches in length, however, its hind legs can reach a whopping seven to ten inches! This makes the frog very good at jumping, making a maximum leap about nine times its body length. Bullfrogs are good swimmers, kicking out with their strong hind legs. They are helped by their webbed hind feet. Bullfrogs help humans by eating large amounts of pesky insects, such as mosquitos. Many people eat bullfrog legs. Bullfrogs are frequently used for medical research, since they are currently dissected in many high school Biology classes. Bullfrogs hibernate in the winter, usually burying themselves in mud. Reproduction The males make calls only during the rainy season, which is when they come out of to breed in f water. They tend to congregate around watering holes. The call of Pyxicephalus adspersus is composed of loud, throaty bellows and deep grunts. These frogs can get rather territorial during mating and begin their mating calls only when they have established their territory. Bull frogs have a deep, loud call which can be heard up to a quarter of a mile. Fertilization is external in frogs. The female bullfrog deposits her eggs in the water and the male simultaneously releases sperm. A female may produce up to 20,000 eggs in one clutch.

Answer 3

e.g. Frogs Webbed toes for propulsion in water

Strong legs for swimming/jumping

Permeable skin for gas exchange

Strong legs for jumping

Variety of feet modifications for tree climbing or burrowing

Lungs for ventilation/respiration above water

Answer 4

Adaptions for living on land include the tympanic membrane, used for hearing, and the nictitating membrane, which is a covering over the eye to keep it moist. They have lungs to breathe air. They also developed limbs for locomotion.

They are still dependant on water though, because they need to lay their eggs in water to prevent them from drying out. They also need to keep their skin moist, as they breathe by diffusion through their skin.

Answer 5

to walk around and not get dry from not being in the water all day, they loose their talls and grow legs also lungs

Answer 6

Frog's legs are adapted on moving on land as the back legs are long and springy, enabling it to hop from place to place. from land to water to avoid predators

Answer 7

Legs and feet

Answer 8

Limb-like fins and lungs
