Amphibians: Frogs in the Wild

Characteristics of Frogs

• The most common species of frog found in India is not specified (but the Indian bullfrog and the Asian giant toad are common species found in India).

Thermoregulation in Frogs

• Animals like frogs, whose body temperature varies with the temperature of the environment, are called ectothermic.

Camouflage in Frogs

• The term for the protective coloration displayed by frogs to hide from their enemies is camouflage or cryptic coloration.

Adaptations of Frogs

• Frogs take shelter in deep burrows to protect themselves from extreme heat and cold during summer and winter periods.
• Frogs absorb water through their skin.

Anatomy of Frogs

• The primary function of the nictitating membrane in frogs is to protect their eyes.
• The hind limbs of frogs differ from the fore limbs in terms of size and structure, with hind limbs being larger and more powerful for jumping.
• Male frogs are distinguished from female frogs by their vocal cords and other sexual characteristics.

Digestive System of Frogs

• The digestive system of frogs differs from herbivores in that it is adapted for meat digestion.

Respiratory System of Frogs

• The skin serves as the aquatic respiratory organ for frogs, allowing them to breathe through their skin.

Tissues and Organs

• The term that describes the organisation of specific proportions of tissues to form organs like stomach, lung, heart, and kidney is histology.
• A group of similar cells along with intercellular substances that perform a specific function is called tissue.
• The body of a simple organism like Hydra is characterized by the presence of three primary layers of cells (ectoderm, mesoderm, and endoderm).

Complex Animals

• The body of complex animals is made up of four basic types of tissues: epithelial, connective, muscle, and nervous tissue.
• When two or more organs perform a common function by their physical and/or chemical interaction, it is called an organ system.

Morphology of Animals

• The study of the form or externally visible features of animals is called morphology.
• The study of the morphology of internal organs in animals is called visceral morphology.

Classification of Frogs

• Frogs belong to the class Amphibia of phylum Chordata.

Miscellaneous

• The heart of a frog consists of muscular tissue.
