Study Notes
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.
Test your knowledge about the characteristics and habits of frogs, such as their ability to live both on land and in freshwater, their classification in the phylum Chordata, and their adaptation as cold-blooded animals. Learn more about the fascinating world of frogs through this quiz.
