Integument is the outer covering of an organism, which includes the skin, scales, feathers, and other structures that protect the body. The structure of integument varies among the different classes of vertebrates, and each class has unique derivatives of integument that serve specific functions.
1. Fish (Class: Pisces):
- The integument of fish is composed of scales, which are bony plates that cover the body and provide protection.
- Fish also have mucous glands in their skin that secrete a slimy substance to reduce friction in the water.
2. Amphibians (Class: Amphibia):
- The integument of amphibians is thin and permeable, allowing for gas exchange through the skin.
- Amphibians have mucous glands in their skin that help keep it moist and protect against dehydration.
3. Reptiles (Class: Reptilia):
- Reptiles have scales made of keratin, a tough protein that provides protection and waterproofing.
- Some reptiles, such as snakes, have specialized scales called scutes that help with locomotion and protection.
4. Birds (Class: Aves):
- Birds have feathers, which are specialized structures made of keratin that provide insulation, protection, and aid in flight.
- Birds also have oil glands in their skin that secrete a waterproofing substance to keep their feathers in good condition.
5. Mammals (Class: Mammalia):
- Mammals have hair, which is made of keratin and provides insulation, protection, and sensory functions.
- Mammals also have sweat glands, sebaceous glands, and mammary glands in their skin that produce sweat, oil, and milk, respectively.
In addition to these structures, some vertebrates have specialized integumentary derivatives such as horns, claws, and hooves, which serve various functions such as defense, digging, and traction. These structures are made of keratin or bone and are unique to certain groups of vertebrates.
