RRB NTPC Science Animal Kingdom Questions With Solution

RRB NTPC Science Animal Kingdom is a crucial topic in the general science section. Questions from this area are frequently asked in multiple-choice and one-liner formats. Understanding RRB NTPC Science Animal Kingdom helps candidates answer questions on classification, physiology, and unique adaptations of animals.

The Animal Kingdom, or Jantu Jagat, is diverse. It includes organisms ranging from simple single-celled protozoans to complex mammals. Covered here is the RRB NTPC Science Animal Kingdom syllabus in a structured manner. It also explains important examples, scientific names, and exam-focused facts as per 2025 trends.

Why RRB NTPC Science Animal Kingdom Is Important for Exams?

RRB NTPC Science Animal Kingdom is a high-yield area. Questions often test knowledge of animal classification, respiratory systems, and notable species. Candidates frequently lose marks due to confusion between similar animals.

This topic combines static GK and science facts, making it essential for SSC, Railway, and other government exams. Revision of animal physiology, phyla, and unique traits improves accuracy.

Animal Classification in RRB NTPC Science Animal Kingdom

Animals are classified based on structure, physiology, and evolutionary traits. The RRB NTPC Science Animal Kingdom syllabus emphasizes the following:

• Phylum Chordata: Animals with a backbone (vertebrates). Examples: Homo sapiens, Rana tigrina, Pavo cristatus.

• Phylum Mollusca: Soft-bodied animals with a shell. Example: Helix (snail).

• Phylum Arthropoda: Jointed limbs. Examples: insects, spiders, crabs. Most abundant phylum.

• Phylum Coelenterata (Cnidaria): Transparent bodies, no blood. Example: Jellyfish (Aurelia).

• Phylum Porifera: Porous body. Example: Sponge. Pores are Ostia, exit opening is Osculum.

• Phylum Protozoa: Single-celled organisms. Example: Plasmodium, amoeba.

Warm-blooded animals maintain constant body temperature. Example: Bats, whales, dolphins.
Cold-blooded animals have body temperature dependent on the environment. Example: Snakes, lizards, frogs.

Scientific names are important for exams:

• Frog: Rana tigrina

• Peacock: Pavo cristatus

• Human: Homo sapiens

Animal Physiology and Adaptations

Animals show diverse adaptations to survive in their environments. RRB NTPC Science Animal Kingdom questions often test physiology:

• Respiration:

• Fish breathe with gills.

• Frogs use skin respiration during hibernation.

• Birds (e.g., pigeons) use lungs.

• Cockroaches breathe through spiracles connected to tracheae.

• Whales and dolphins breathe air through lungs, making them mammals.

• Echolocation: Bats use ultrasonic waves for navigation and obstacle detection.

• Reproduction:

• Male sea horses give birth.

• Mammals give birth to live young and nurse with milk.

• Unique Traits:

• Octopus has blue blood due to hemocyanin and can regenerate lost arms.

• Starfish belongs to Echinodermata, not fish.

• Sharks have a cartilaginous skeleton, no bones.

Notable Animal Species for RRB NTPC Science Animal Kingdom

Key animals often asked in exams include:

• Largest Mammal: Blue whale

• Largest Teeth: Sperm whale

• Largest Bird: Ostrich (lays largest egg)

• Smallest Monkey: Gibbon

• Largest Monkey: Gorilla

• Only bird flying backwards: Hummingbird

• National Aquatic Animal of India: Ganges river dolphin

Other notable facts:

• Bats hang upside down due to foot structure.

• Cockroach uses spiracles for breathing.

• Protozoan parasites like Plasmodium cause malaria.

• Sleeping sickness is caused by Trypanosoma gambiense via tsetse fly.
