Scales are usually found on cold-blooded animals – the ones whose body temperature change with that of the surroundings. Compared to fur, scales absorb or dissipate the heat more readily, as needed by these animals. The scales also help the animals in camouflage.

How do scales help an animal survive?
Thick, prickly scales on a reptile can help protect it from predators. Scales can make it difficult for predators to bite or attack their prey and may even injure the predator. In some reptiles, the color of their scales can fool predators into backing off.
What is the purpose of scales?
Scale, in zoology, small plate or shield forming part of the outer skin layers of certain animals. Scales provide protection from the environment and from predators.
How do scales help reptiles survive?
Reptiles have a tough, dry, scaly skin that protects them from predators and allows them to live in dry places by reducing water loss. Reptilian scales are made of keratin, like hair, and found in an overlapping arrangement. This creates a sort of environmental shield for the animal.
How do scales help fish?
Scales protect fish from predators and parasites and reduce friction with the water. Multiple, overlapping scales provide a flexible covering that allows fish to move easily while swimming.
What covers the body of animal?
Skin: the outer covering of an animal that protects it from its environment. Keratin: a type of protein that forms many of the epidermal structures in vertebrates, such as hair, nails, claws, feather, and some kinds of scales.
Do crocodiles have scales or skin?
The skin of crocodiles and alligators protects against water loss via bony scales called ‘scutes.
How do you explain a scale?
The scale is shown as the length in the drawing, then a colon (“:”), then the matching length on the real thing. Example: this drawing has a scale of “1:10”, so anything drawn with the size of “1” would have a size of “10” in the real world, so a measurement of 150mm on the drawing would be 1500mm on the real horse.
What does a scale help us to find?
The scale can usually be found in a corner of the map and will tell you the ratio of the two units of measure. Other scales might use a ratio to show the scale which shows how many real life units are represented by one map unit, such as how many inches in real life one inch on the map represents.
What are the 4 main types of scales?
Each of the four scales (i.e., nominal, ordinal, interval, and ratio ) provides a different type of information. Measurement refers to the assignment of numbers in a meaningful way, and understanding measurement scales is important to interpreting the numbers assigned to people, objects, and events.
What is an interesting fact about reptiles?

Can humans have scales?
Ichthyosis vulgaris (ik-thee-O-sis vul-GAY-ris) is an inherited skin disorder in which dead skin cells accumulate in thick, dry scales on your skin’s surface.
What are animal scales for?
In most biological nomenclature, a scale (Greek λεπίς lepis, Latin squama) is a small rigid plate that grows out of an animal’s skin to provide protection. There are various types of scales according to shape and to class of animal.
Which type of scale is present in the body of shark?
Sharks have placoid scales, bony, spiny projections with an enamel-like covering. These scales have the same structure as their teeth, and are also referred to as dermal denticles (dermal=skin, denticle=teeth).
Why the fish has scales summary?
Fish have scales for many reasons. Firstly, to protect the skin of the fish from attacks from predators, parasites and other injuries. Secondly, scales overlap each other in the same way that an armour would protect a person. Hence, providing a layer of protection for the fish.
Why do we scale fish?
A fish scale is a small rigid plate that grows out of the skin of a fish. The skin of most fishes is covered with these protective scales, which can also provide effective camouflage through the use of reflection and colouration, as well as possible hydrodynamic advantages.
