One of the key adaptations that permitted reptiles to live on land was the development of their scaly skin, containing the protein keratin and waxy lipids, which prevented water loss from the skin.Apr 25, 2013
What Has Allowed Reptiles To Move Further From The Aquatic Environment?
Laying eggs that can survive on land is a major adaptation allowing reptiles to live away from aquatic environments. Amphibians tend to lay soft, gelatinous eggs, and most use forms of external fertilization. Such eggs wouldn’t survive the dry conditions found on land.
What Permits Reptiles To Thrive In Arid Environments?
What permits reptiles to thrive in arid environments? A large number of prey and a limited number of predators are available in the desert. Their scales contain the protein keratin, which helps prevent dehydration.
Which Adaptation Is Relatively Less Developed In Flightless Birds Such As Penguins And Ostriches?
A group of feathered, endothermic dinosaurs that survived the Cretaceous mass extinction. Which bird adaptation is probably less well-developed in flightless birds such as penguins and ostriches? have hair and mammary glands.
Do Reptiles Have Amniotic Eggs?
B. Amniotic egg with several labeled extraembryonic membranes, found in reptiles and birds. In most mammals, some of these membranes will form the embryonic portion of the placenta.

What Glass Is Used For Reptile Enclosures?
Glass is the classic material for terrariums. Most pet shops will stock glass tanks, in a wide variety of sizes and shapes. These tanks tend to cost less than acrylic tanks.
Why Can Reptiles Have Offspring In Very Dry Conditiont
Their eggs are covered by a hard shell, providing a sealed environment for the developing embryo, which does not depend on external sources of water. These two features have enabled reptiles successfully to colonize very dry habitats, including deserts.
Why Are A Reptiles Eggs Able To Survive In Dry Places?
Primitive reptiles were able to radiate into drier habitats than amphibians because of the amniote egg with a leathery or hard shell, and because of their relatively impermeable skin with scales. Populations no longer were concentrated near water sources and embryos developed directly into small adults at hatching.
Why Do Reptiles Not Need Water To Reproduce?
Most reptiles reproduce sexually and have internal fertilization. Reptile eggs are amniotic, so they can be laid on land instead of in water.
How Have Reptiles Evolved To Enable Them To No Longer Be Dependent On The Water?
Because of the development of impermeable, scaly skin, reptiles were able to move onto land since their skin could not be used for respiration in water.Jun 8, 2022
Why Can Lizards Survive In Dry Areas?
Lizards use burrows, or underground holes, as a means of adapting to the desert heat. They descend into these burrows to escape the heat. They may use the burrow as a temporary shelter during the heat of the day or as a long-term survival technique.
Which Era Characterized By The Extinction Of Reptiles And The Appearance Of Mammals
The Mesozoic extinction event. The Mesozoic came to an abrupt end 66 million years ago in a dramatic extinction event.
Which Characterized By The Extinction Of Reptiles And The Appearance Of Mammals Is Significant In Geologic History A Triassic B Mesozoic C Paleozoic?
The Mesozoic closed with an extinction event that devastated many forms of life. In the oceans all the ammonites, reef-building rudist bivalves, and marine reptiles died off, as did 90 percent of the coccolithophores (single-celled plantlike plankton) and foraminifera (single-celled animal-like plankton).
Which Era Is Known As The Age Of Reptiles?
Assorted parareptiles occurred throughout the Permian Period (299 million to 251 million years ago), but they largely disappeared from the fossil record by the beginning of what was to become known as the “Age of Reptiles,” the Mesozoic Era (251 million to 65.5 million years ago).
What Era Is Known As The Age Of Mammals?
The Cenozoic spans only about 65 million years, from the end of the Cretaceous Period and the extinction of non-avian dinosaurs to the present. The Cenozoic is sometimes called the Age of Mammals, because the largest land animals have been mammals during that time.
When Was The Age Of Mammals Fishes And Reptiles?
The Triassic period, from 252 million to 200 million years ago, saw the rise of reptiles and the first dinosaurs. The Jurassic period, from about 200 million to 145 million years ago, ushered in birds and mammals.Jan 7, 2015

A more controversial emotion in reptiles is the concept of pleasure, or even love. Many feel that they have not developed this emotion, as it does not naturally benefit them. However, most reptiles do seem to recognize people who frequently handle and feed them.
What Are The Basic Differences Between The Scales Of Fish And Reptiles
Fish scales are smooth to help them glide through the water, and some reflect light to help camouflage them underwater. Unlike reptiles, the scales of bony fish are made of enamel and dentine (like teeth) and they can be detached individually from the skin.
Do Reptiles And Fish Have Scales?
Most reptiles and fish bear scaly outer coverings, although exceptions exist in both categories. For example, catfish have no external scales and snakes occasionally exhibit a genetic mutation in which they fail to produce scales.Nov 1, 2017
What Is The Function Of Scales In Fishes And Reptiles?
Scales provide protection from the environment and from predators. Fish scales are formed of bone from the deeper, or dermal, skin layer. The elasmobranchs (e.g., sharks) have placoid scales, which are bony, spiny projections with an enamel-like covering.
What Kind Of Scales Do Reptiles Have?
Reptile skin is covered with scutes or scales which, along with many other characteristics, distinguish reptiles from animals of other classes. They are made of alpha and beta-keratin and are formed from the epidermis (contrary to fish, in which the scales are formed from the dermis).

Described as ‘the closest thing to a real life dragon,’ scientists have discovered a new ‘fearsome beast’ from the time of the dinosaurs!
