Skin Although melanin is found in the skin of many species, in the reptiles, the amphibians, and fish, the epidermis is often relatively colourless. Instead, the colour of the skin is largely due to chromatophores in the dermis, which, in addition to melanin, may contain guanine or carotenoid pigments.kin of a different nature exists in amphibians, reptiles, and birds. All mammals have some hair on their skin, even marine mammals which appear to be hairless. The skin interfaces with the environment and is the first line of defense from external factors.

Contents: Amphibian vs Reptile Amphibians live double lives — one in water with gills and the other on land by growing lungs as they age. They are vertebrates and cold blooded (ectothermic). Early amphibians, a crucial link from fish to terrestrial reptiles, were the first animals to leave the sea and venture onto the land.s compared to reptiles, amphibians have smooth skin. The skin of most amphibians is not water-proof unlike reptiles. Although most of the amphibians have lungs, they usually breathe through their skin and lining of their mouth, whereas most reptiles do not. Most amphibians have four limbs.

- Ectothermoc or cold blooded animals like frogs, toads, salamanders, newts, and caecilians metamorphose from a juvenile, water breathing form to an adult, air breathing form. Amphibians are four limbed animals. As by their ancestors the fish the amphibians lay eggs in the water. Amphibians are similar to the reptiles.

Skin On some animals, the skin is very hard and thick, and can be processed to create leather. Reptiles and fish have hard protective scales on their skin for protection, and birds have hard feathers, all made of tough β- keratins.Amphibian skin is not a strong barrier, especially regarding the passage of chemicals via skin and is often subject to osmosis and diffusive forces.eptiles and fish have hard protective scales on their skin for protection, and birds have hard feathers, all made of tough β- keratins.

Epidermis The epidermis is a protective outer covering of many plants and animals. It may be comprised of a single layer, as in plants, or of several layers of cells on top of the dermis, as in those of vertebrate animals. The primary role of the epidermis is to protect the more susceptible layers of the skin.

- Frogs and salamanders are amphibians. Amphibians are animals that live part of their lives in water and part on land. They usually have soft, moist skin that is protected by a slippery layer of mucus. They also tend to live in moist places or near water to keep their bodies from drying out.mphibians are animals that live part of their lives in water and part on land.

Accessory Organs of the Skin The following accessory organs (skin derivatives) are embedded in the skin: 1  Hairs are elongated filaments of keratinized epithelial cells that arise and emerge from the skin of mammals. Hair is composed of the following structures:  The hair shaft is the portion of the hair that is visible on the surface of the skin.

- Frogs, salamanders, and newts all have smooth, wet skin. A toad's skin can be warty and dry.Reptiles can live in many different types of habitats, whereas amphibians cannot. Reptiles can be found in temperate and tropical climates around the world.

Epidermis (botany) Epidermis (botany) The epidermis (from the Greek ἐπιδερμίς, meaning over-skin) is a single layer of cells that covers the leaves, flowers, roots and stems of plants. It forms a boundary between the plant and the external environment.

- Frogs and toads have a 'lycra' type skin that protects them from from injury and disease. It comes in wonderful variations of colour and patterns. Frog skin is water permiable, this means it can let water in and out. Frogs don't often drink with their mouths, they absorb water through their skin.

- Scientific Name: Order Anura. Description: Like frogs, toads are amphibians. They differ from most frogs in that they have dry skin, warts, crests behind the eyes, and parotoid glands. The parotoid glands produce a poisonous secretion that helps to defend the toad from predators.

Poison gland The poison glands of snakes are modified oral or salivary glands. Amphibian glands are simple, acinous, holocrine, with granular secretion. In some cases these amphibian poison glands produce mucus by a merocrine method of secretion. These glands function as protective devices.

Sweat Glands Sweat glands, also known as sudoriferous glands, are small tubular structures of skin that produce sweat. They are distributed all over the skin, except lips, glans penis and nail bed. These glands are of two types: Eccrine and Apocrine.ccrine glands are much more abundant and distributed in almost every part of the skin. Each one of these is a single tube, the deep part of which is coiled into a ball. The coiled part is called body of the gland. It lies in the deeper part of corium or in the subcutaneous tissue. The straight part is called duct.

- 1 The epidermis is the epithelial tissue layer of skin. 2  Hair follicles, sebaceous glands, and sweat glands are epithelial invaginations from the epidermis. 3  The dermis is the connective tissue layer of skin. 4  Embedded within the dermis are hair follicles and sweat glands as well as blood vessels and sensory nerve endings.

Amphibian Amphibians are frogs, toads, salamanders, newts and other cold blooded animals that change from breathing water as a juvenile to breathing air as an adult.Amphibians lay their eggs in water, as their fish ancestors did.nlike other land  animals (amniotes), amphibians lay eggs in water, as their fish  ancestors did. Amphibians are superficially similar to  reptiles.    Amphibians are cold-blooded animals, meaning they do not have a  constant body temperature but instead take on the temperature of  their environment.

Chapter 3 Vertebrates *They have a double life. * They have moist and scaleless skin. * Glands in skin that secrete mucus., which helps the skin keep moist. * Water and gases can pass through the amphibian skin easily, which allows the amphibians to breathe through their skin.

Xerocole Amphibious xerocoles, such as species of the Phyllomedusa genus of frogs, have wax-like coatings on their skin to reduce water loss. The frogs secrete lipids from glands in their skin: when their skin begins to dry out, they move their limbs over the glands on their backs, and wipe the lipids over their bodies.

- They live part of their lives in water and part on land. The early part of every amphibian s life is spent in the water. Amphibian eggs are laid and hatch in water. Much like fish, young amphibians breathe through gills in water and do not have legs.As they grow, amphibians go through a gradual change to develop legs, lungs, and other body parts in the process of becoming an adult.mphibians. Amphibians are often mistaken for reptiles.A toad is not a reptile and a snake is not an amphibian. The most well-known amphibian representatives are salamander, newts, frogs, toads, and caecilians.

Difference between Reptiles and Amphibians Amphibians are animals that live part of their lives in water and part on land. They are vertebrates and are also ectothermic; they cannot regulate their own body heat, so they depend on sunlight to become warm and active.

Amphibians Fun Facts about Amphibians. 1  Most amphibians have thin, moist skin that helps them to breathe. 2  Amphibians are considered vertebrates as they have a backbone. 3  Frogs swallow their food whole. 4  Frogs cannot live in salt water. 5  All amphibians have gills, some only as larvae and others for their entire lives. It is a myth that you can get warts from touching a frog or toad. A group of frogs is called an army.

- Thanks! - Tim. All amphibians have poisonous skin secretions, including salamanders, in fact, the skin secretion of the Pacific Newts is among the most toxic compounds known in nature. In spite of this, these animals are harmless to handle, just don t eat them.

What is the structure of the epidermis, dermis, and hypodermis ( including tissue types involved) ? The hypodermis, also called the hypoderm, subcutaneous tissue, or superficial fascia is the lowermost layer of the integumentary system in vertebrates. Types of cells that are found in the hypodermis are fibroblasts, adipose cells, and macrophages. It is derived from the mesoderm, but unlike the dermis, it is not derived from the dermatome region of the mesoderm. In arthropods, the hypodermis is an epidermal layer of cells that secretes the chitinous cuticle.
