Why do male frogs have enlarged thumbs during mating season?
There’s nothing subtle about the wooing of European common frogs. Males grow spiny pads on their thumbs during the breeding season, the better to grip their mates. Technically called amplexus, the male-on-top position allows him to fertilize the eggs just as the female sends them out of her body.
How we can distinguish male and female frog?

Body Size. Females are larger than males in many species of frog. In most frogs and toads, males are on average smaller than females. Because of the size overlap between males and females, larger males do end up mating with smaller females.
Why do frogs get stuck together?
When strolling by a pond, river or large puddle at night, you may see two frogs clinging onto each other. This is a behavior called amplexus: it allows the male frog to place his cloaca near the female’s in order to fertilize her eggs.
How does a male frog attract a female frog for mating?
In early spring the females are swollen with spawn, which the male frogs fertilise as it is laid. The deep, purring croaks are to intimidate other males and attract the attention of females. Male frogs grow pads on their forelegs that help them to grasp the females in an embrace known as amplexus.

What causes a frog to be swollen in the spring?

Why does a frog swell up when it eats a toad?
This unusual bloating is thought to be related to a hormonal imbalance which pulls water into the frog’s body causing it to swell. Symptoms often appear to subside over time but, again, a vet may be able to help by draining the fluid. Toads also inflate themselves as a defence mechanism (to make them look too large to eat).
Why are the tips of my fingers swollen?
In certain cases, swelling can become so severe that it can reduce blood flow or injure nerves and muscles in the forearm and hand. This is especially true with very bad fractures and infections.

Thumb or pollex is vestigial. In case of male frog, the base of first inner finger is thickened, especially in breeding season. It forms the nuptial pad for clasping the female during amplexus. The much elongated and powerful hind limbs or legs arise close together posteriorly from trunk. Each hind limb consists of: the thigh; shank (crus)
Why does my frog have a lot of edema?
In the case of frog dropsy, lymph, the fluid substance that circulates in the lymphatic system, fills the lymph nodes (and does other jobs inside the body), does not drain properly, builds up outside of the normal tissues it usually stays in, and fills the abdominal cavity of a frog, thus causing the edema.
What does a male frog do on top of a female frog?
When a male frog is on top of a female frog, that position of mating is known as amplexus. This amplexus behavior of mating allows the male frog to place his cloaca near the female’s cloaca in order to fertilize her eggs.
