Question

Вывод особенное строение лягушки в воде и на суше

Answer 1

Прекрасно развиты задние конечности с плавательными перепонками и умеренно развиты передние конечности. Хвост отсутствует. С выходом на земную среду необходимо усиление слуха, поэтому появляется среднее ухо с одной косточкой. Глаза приобретают веки и мигательную перепонку. Глазное яблоко спереди, в зависимости от среды меняет выпуклость: на суше оно выпуклое, в воде плоское. Есть органы обаняния, вкуса, осязания. Череп упрщён, более прочный, содержит сросшиеся челюсти. Огромные сквозные глазницы. На верхней челюсти зубы.

The Special Adaptations of Frogs in Water and on Land

Frogs are amphibians that have unique adaptations to thrive both in water and on land. These adaptations allow them to navigate and survive in different environments. Let's explore the special structures and behaviors of frogs in water and on land.

In Water:

Frogs have several adaptations that enable them to live and move efficiently in water:

1. Streamlined Body Shape: Frogs have a streamlined body shape with a tapered head and a long, muscular hindlimb. This body shape helps reduce drag in the water, allowing them to swim swiftly and efficiently.

2. Webbed Feet: Frogs have webbed feet that are specially adapted for swimming. The webbing between their toes increases the surface area of their feet, providing more propulsion and stability in the water.

3. Powerful Hindlimbs: Frogs have strong hindlimbs with well-developed muscles. These muscles allow them to generate powerful kicks, propelling them through the water.

4. Smooth Skin: Frogs have smooth, moist skin that helps them move smoothly through the water. Their skin also allows them to absorb oxygen directly from the water, supplementing their breathing through lungs.

On Land:

When frogs are on land, they exhibit different adaptations to survive and move effectively:

1. Strong Hindlimbs: Frogs' hindlimbs are not only adapted for swimming but also for jumping. Their powerful hindlimbs enable them to make quick and powerful leaps, helping them escape predators and catch prey.

2. Moist Skin: Frogs' skin plays a crucial role in their survival on land as well. It helps them stay moist and prevents dehydration. Frogs can also breathe through their skin, absorbing oxygen from the air when their lungs are not sufficient.

3. Lung Respiration: While frogs primarily respire through their skin in water, on land, they rely more on lung respiration. They have lungs that allow them to breathe air efficiently when they are out of the water.

4. Toe Pads: Many frog species have specialized toe pads that aid in climbing and clinging to various surfaces. These adhesive pads help frogs maintain their grip on trees, rocks, and other objects while they move on land.

In conclusion, frogs have remarkable adaptations that allow them to thrive both in water and on land. Their streamlined body shape, webbed feet, powerful hindlimbs, smooth skin, and specialized toe pads enable them to move efficiently and survive in different environments.
