Frogs are very easily dehydrated and need to keep their skin moist permanently. To support this the hydrophyle (waterbinding) mucus is sectreted.

What glands under a frogs skin keep the skin moist?
Mucous glands
Do some frogs have poison in their skin?
Yes. Frogs (and toads) have mucous glands all over their skin to help keep their skin lubricated. If frogs do not keep their skin moist they will dry out and die. In some species, such as the poison dart frogs, the secretions from these glands are highly toxic. All frogs and toads have a degree of these poisons, even if it is only in retrace amounts, but in some species the concentration of toxins is much greater, providing an effective defence mechanism. The mucous glands in frogs' and toads' skin is different from the parotid glands which some species of toads have just behind their eyes, which contain irritants and other toxins to deter predators.
Why are frogs able to function with small lungs?
Frogs have a highly efficient respiratory system that allows them to absorb oxygen through their skin and utilize their buccal pumping mechanism to circulate air through their lungs. This combination of adaptations allows frogs to thrive despite having relatively small lungs.
Which glands lubricate the frogs skin?
Frogs have mucous glands in their skin that secrete mucus, which helps to keep their skin moist and lubricated. This is vital for their respiration, as frogs absorb oxygen through their skin, and it also aids in preventing dehydration. Additionally, some frogs have poison glands that can secrete toxins as a defense mechanism. The combination of these glands plays a crucial role in the frog's survival in its environment.
What do bright colors generally represent when observed on frogs?
The mucous the frog secretes from its skin typically has a foul smell and is usually a poison to help ward off predators.
Can chlorine kill a frog?
Yes, chlorine can harm or kill frogs. Frogs have permeable skin that allows them to absorb substances in their environments, including chemicals like chlorine. Exposure to chlorine can damage a frog's skin and mucous membranes, leading to illness or death.
Why does the respiration system of frogs differs from mammals because frogs?
Frogs have underdeveloped lungs, so they must have a moist skin so that oxygen can diffuse into their bodies. Their lungs do not function well enough to be used on their own.
Do toads have bumpy skin and frogs not?
Correct. Frogs have smooth skin which is slippery and delicate, but toads have drier skin with warts.
Are frogs scaly?
Frogs have wet, moist skin. Their skin is not scaly, but it is smooth.
What environment can frogs not function in?
Frogs cannot function well in extremely dry environments, such as deserts, as they rely heavily on moisture for hydration and skin respiration. Their permeable skin makes them susceptible to dehydration, making it challenging for them to survive in arid conditions. Additionally, polluted or heavily contaminated environments can also be detrimental, as toxins can harm their sensitive skin and overall health.
What is the function of mucous in the nose?
the mucous traps inspired dust, bacteria, and other debris.
