How are amphibians different from repetiles?
Reptiles live on dry land; amphibians live on land as well as in water.
Name four characteristics of amphibians that explain why amphibians need moist habitats?
1) When they are juveniles, they are in an aquatic larval or 'tadpole' stage that need water to breathe thru their primitive gills. 2) Amphibians have smooth, scaleless skin which is permeable to water. Water can evaporate easily from the skin, and an amphibian can dry up and die in a few hours if it does not have access to water. Thus amphibians tend to be active at times when evaporation is minimized: at night and when it rains.However, this same skin permeability makes it possible for amphibians to obtain moisture from sources besides pools of water. This means that amphibians can live in very dry climates, like deserts, and when the dry season arrives, they just burrow underground and pull in moisture from the surrounding soil. Despite this, the amphibian's tie to water remains: their eggs must be laid in water in order to survive. Reference: http://redpath-museum.mcgill.ca/Qbp/herps/herps.html
Did reptiles evolve from amphibians?
No, they did not.
Why do plants in dry habitats have their stomas in a sunken pit on their leaves?
Plants in dry habitats have sunken stomata to reduce water loss through transpiration. The sunken pits create a more humid environment around the stomata, making it harder for water to evaporate. This adaptation helps the plant conserve water and survive in arid conditions.
What is the inactivity of amphibians during hot dry weather?
During hot dry weather, amphibians tend to become more inactive to conserve moisture and avoid dehydration. They may seek shelter in cool, damp areas or burrow underground to escape the heat and reduce water loss through their skin. This behavior helps them survive until conditions become more favorable for activity.
What is a seasonal pond called?
A seasonal pond is often referred to as a "vernal pool." These temporary bodies of water typically fill with rainwater in the spring and may dry up during the summer months. Vernal pools are important habitats for various wildlife, particularly amphibians and invertebrates, that rely on these ecosystems for breeding and development. They are characterized by their unique seasonal wet-dry cycles.
Vertebrates that have dry scaly skin are called?
amphibians
Why are reptiles better suited to deserts than amphibians?
Reptiles are better suited to deserts than amphibians primarily due to their waterproof skin, which prevents water loss in arid environments. They are ectothermic, relying on external heat sources to regulate their body temperature, allowing them to thrive in fluctuating desert conditions. In contrast, amphibians require moist environments to keep their skin hydrated and often depend on standing water for reproduction, making them less adaptable to dry habitats.
Why do eggs of amphibians require moist environment?
So they do not dry out and die.If the soil is moist it absorbed the rays of the sun heating the egg. Also amphibians love in moist conditions so it is easier to start a new life
Why can't amphibians live in dry places?
Because amphibians need to be moist.
Does an amphibians have dry skin?
Toads do.
Why are reptiles more suited for the desert than amphibians?
Amphibians require water to reproduce as their eggs do not have a water proof shell. that requires that the developing young be in water. Also, amphibians go through a process of metamorphosis Reptiles, most of them, lay eggs that are more waterproof and do not dry out. The young of reptiles are born as miniatures of the adults and do not require water sources to mature.

How is the skin of reptiles and amphibians similar?
Reptiles: Dry, scaly skin Amphibians: Wet, slimy skin

Why are amphibians unsuccessful on land vertebrates?
Amphibians are cold blooded so they cannot regulate temperature.They need water for egg lying.Their eggs are not covered with shell so they may become dry on land and eggs may be wasted.Their skin is so naked, no external covering
Are amphibians and reptiles both slimy?
No. Most amphibians apart from newts and toads are slimy but reptiles have dry skin.
