How do animals escape the heat in summer?

1, hippos, seahorses and other animals living in water will secrete sweat.

Hippos, seahorses and other animals can only reduce their body temperature by soaking in water on weekdays, but they cannot avoid ultraviolet radiation. In hot summer, ultraviolet rays can also do great harm to their skin.

Hippos and seahorses have a unique ability. Their skin can secrete a pink sweat, which can quickly harden and form a hard shell, thus protecting them from ultraviolet rays. As a natural sunscreen for hippos and seahorses, sweat can also inhibit the growth of bacteria.

Elephants, buffaloes, rhinos and other large animals use mud to escape the heat.

In summer, besides bathing in water, mud bath is the most common way for large animals such as elephants and buffaloes to escape the heat. Don't underestimate the dirty mud, it can not only effectively protect against the sun, but also reduce the body temperature and resist the invasion of mosquitoes because of the continuous evaporation of the water contained.

When the mud is dry, it can also take away parasites, bacteria, dead skin, etc. from the skin of these animals due to the hot weather, and play a cleaning role.

3. Snails will curl up in their shells in summer and sleep in summer.

Most snails like to stay in a humid environment. When the hot and dry summer comes, the snail will secrete a layer of mucus on its body surface to seal its hard shell, and it will curl up in the shell to escape the heat. For example, snails living in the African desert, in summer, they will shrink into their hard shells, and then drill into the gravel to "sleep in the summer" and spend the whole summer.

Tigers and brown bears like to cool down with cold water in summer.

When summer comes, tigers and brown bears lose their former prestige. Tigers in the zoo like to bathe, swim or stay in the shade in summer. After waking up in the morning, the seemingly honest brown bear will plunge into the pool and stay in the water all day.

Rabbits need to radiate their body temperature with their ears.

Some animals rely on body parts to cool down, such as rabbits. Rabbits should put up two long ears when they run. This is because the sweat glands of rabbits are underdeveloped, and they can only rely on the abundant capillaries in their ears to radiate a lot of heat generated in their bodies.

People's Daily Online-World Environment Day arrived as scheduled to see how animals cool down in summer.
