Introduction to Wildlife and Ecology
Written by Abin Alex and Anu Joseph.
Abstract
Good wildlife pictures come from knowing the animal before you press the shutter. This guide explains what wildlife is, how animals are classified from kingdom to species, and the difference between vertebrates and invertebrates. It then covers ecology, from the individual to the biosphere, habitat and niche, food chains and animal behaviour, and ends with field ethics and the Wildlife (Protection) Act, 1972. Nine diagrams support the ideas.
Keywords: Wildlife; ecology; habitat; niche; classification; wildlife photography ethics
What is wildlife?
Short answer. Animals living in their natural habitat, outside human control.
- Wildlife means animals living in their natural habitat and not in the possession or control of humans. The word also covers the native fauna, and sometimes flora, of a region.
- Wildlife lives in every ecosystem: deserts, forests, rain forests, plains and grasslands, and even developed urban sites.
- India's wildlife includes the Bengal tiger, Asiatic lion, leopards, deer such as chital and hangul, the Indian elephant and the Indian rhinoceros. Four national symbols are in Figure 1.
- Each animal, from the blue whale to the tiniest insect, is adapted to its habitat through body covering, body size, eye placement, breathing and feeding organs, and kinds of feet.
List five wild animals within an hour of your home. Note where each one lives.
A documentary on nature starts with the same survey of who lives where.
Cham tipLearn who lives where before you plan the shoot.
Cham taskWrite five local species and one adaptation for each.
Check yourself: What is wildlife?
Animals living in their natural habitat, outside human control.
How are animals classified?
Short answer. Seven Linnaean ranks, from kingdom down to species.
- Classification organises living things by shared characteristics. The Linnaean ranks, from broadest to most specific, are kingdom, phylum, class, order, family, genus and species (Hjørland, 2008) (Figure 2).
- Carl Linnaeus is called the father of taxonomy. His system used two kingdoms, animals and plants. Later systems added more; R. H. Whittaker proposed five in 1969.
- The wolf is placed in Animalia, Chordata, Mammalia, Carnivora, Canidae, Canis and then the species. Dogs, wolves, jackals and foxes share the family Canidae, with its pointed snout.
- Cats and bears join the dogs at the level of the order Carnivora, the meat-eating mammals.
Place a tiger, a leopard and a chital in the ladder. Find where each pair separates.
Naming species correctly belongs in captions and film credits too.
Cham tipUse the scientific name in the caption of a serious wildlife picture.
Cham taskWrite the seven ranks for one animal you photographed.
Check yourself: How many Linnaean ranks are there?
Seven.
What are vertebrates, invertebrates and species?
Short answer. Animals with and without a backbone, and the species as the basic unit.
- Vertebrates, or Chordata, have a backbone, a notochord and a vertebral column. They include fish, amphibians, reptiles, birds and mammals. Invertebrates have no backbone (Figure 3).
- Invertebrate groups include molluscs, arthropods, annelids, roundworms, flatworms, cnidarians, echinoderms and sponges.
- A species is a group whose members can interbreed and have fertile young. Wolf and jackal are different species of the same genus (Figure 4).
- Photographers meet more invertebrates than vertebrates. The Insect and Reptile Photography guide covers those subjects.
Photograph one animal from each vertebrate group and label it.
A wildlife film often needs coverage of several groups in one habitat.
Cham tipGroup first, then identify the species.
Cham taskName three vertebrate groups and one invertebrate group.
Check yourself: What do vertebrates have?
A backbone.
What is ecology?
Short answer. The study of how living things relate to each other and their environment.
- Ecology is the scientific study of the relationship of living organisms with each other and with their environment (NIOS, n.d.). The word comes from the Greek oikos, meaning home.
- Ecology is studied at six levels: individual, population, community, ecosystem, biome and biosphere (NIOS, n.d.) (Figure 5).
- Biotic factors are living components. Abiotic factors are non-living ones such as air, water, soil, rocks, sunlight and rainfall (NIOS, n.d.) (Figure 6).
- A population is a group of interbreeding individuals of one species in an area at a given time. A community is populations of different organisms sharing a habitat. An ecosystem is organisms and their environment working as one unit (NIOS, n.d.).
Draw the six levels for the place nearest to you.
A setting in a documentary is an ecosystem. Show its living and non-living parts.
Cham tipInclude the habitat, not only the animal.
Cham taskName the biotic and abiotic factors in one local scene.
Check yourself: What are abiotic factors?
Non-living parts such as air, water, soil and sunlight.
What are habitat and niche?
Short answer. Habitat is the place; niche is the role.
- A habitat is the physical environment in which an organism lives (NIOS, n.d.). A habitat supports many species.
- A niche is the sum of an organism's activities and relationships as it gets resources to survive and reproduce (NIOS, n.d.) (Figure 7).
- A predator eats other animals. Prey is hunted for food. A food chain shows how energy passes between them (Figure 8).
Photograph one predator and its prey habitat. Write the niche in one sentence.
A single film frame can show the habitat. The action shows the niche.
Cham tipShow what the animal does, not only where it stands.
Cham taskDraw a three-link food chain from a place you know.
Check yourself: Which is a place, habitat or niche?
Habitat.
What is ethology?
Short answer. The scientific study of animal behaviour in natural conditions.
- Ethology is the scientific and objective study of animal behaviour, especially under natural conditions. The word comes from the Greek ethos, meaning character.
- Wildlife ecology studies animal populations and how to help them. A wildlife photographer captures wild flora and fauna and contributes to awareness, education, research, conservation and tourism.
- Knowing behaviour lets you predict a moment. You will know when an animal rests, hunts, moves or guards young. See the Mammals of India guide for examples.
Watch one animal for 30 minutes without a camera. Write its sequence of actions.
Waiting and watching is the same craft as observing actors before a take.
Cham tipWatch before you shoot.
Cham taskWrite a one-page behaviour log of one local animal.
Check yourself: What does ethology study?
Animal behaviour in natural conditions.
How should wildlife photographers behave?
Short answer. Keep your distance, never bait, protect nests and caption honestly.
- Use a long lens and stay far enough away that animals behave naturally. If an animal flushes, freezes or shows stress, back away (Audubon, 2026) (Figure 9).
- Never lure animals with bait or recorded calls. Avoid flash, especially on nocturnal birds. Keep a wide berth from nests and limit your time near them (Audubon, 2026).
- Think before you share a sensitive location, and remove GPS data from pictures of rare species (Audubon, 2026).
- Photograph captive animals only at accredited zoos or sanctuaries, and say so in the caption (Audubon, 2026). See the Photojournalism Ethics guide for the wider rule of honest captions.
Write your own code of conduct in five lines before your next outing.
A film unit in the wild follows the same rules for crew conduct.
Cham tipThe animal comes first, the picture second.
Cham taskWrite five rules you will follow on your next wildlife outing.
Check yourself: Is baiting acceptable?
No.
What does Indian law say about wildlife?
Short answer. The Wildlife (Protection) Act, 1972 protects species and areas.
- The Wildlife (Protection) Act, 1972 sets up protected areas such as sanctuaries and national parks, and tiger reserves on the recommendation of the National Tiger Conservation Authority (Drishti IAS, n.d.).
- It lists animals in schedules. Schedule I covers endangered species such as the Bengal tiger and rhinoceros, with the strictest penalties. Schedule II covers highly protected animals. Schedules III and IV cover other protected species. Schedule V lists vermin. Schedule VI lists specified plants (Drishti IAS, n.d.).
- Hunting animals in Schedules I to IV is prohibited except in narrow cases with the Chief Wildlife Warden's permission (Drishti IAS, n.d.).
- The source does not cover photography. Check entry permits and rules with the forest department before you visit any park or sanctuary.
Find the forest department rules for the park nearest you. List what a photographer needs.
Filming in a protected area needs permission in the same way.
Cham tipAsk for permission first and keep the paper with you.
Cham taskList the permits needed to photograph in one protected area.
Check yourself: Which schedule has the strictest penalties?
Schedule I.
