Let's solve this worksheet step by step.
Worksheet Title: Special Class
Objective: Identify the different types of mammals shown in the images and write their characteristics.
---
We are given three pictures of mammals. Let’s identify each one and list key characteristics.
---
1. First Image: Echidna (Spiny Anteater)
-
Type: Monotreme
(Monotremes are mammals that lay eggs instead of giving birth to live young.)
-
Characteristics:
- Egg-laying mammal (only three species of monotremes exist).
- Covered in spines or fur.
- Long snout used for detecting ants and termites.
- Uses electroreception to find prey.
- Found in Australia and New Guinea.
- Has a beak-like mouth and no teeth.
- Female lays one egg at a time, which hatches in a pouch.
---
2. Second Image: Koala
-
Type: Marsupial
(Marsupials give birth to underdeveloped young, which continue to develop in a pouch.)
-
Characteristics:
- Native to Australia.
- Lives in eucalyptus trees.
- Eats only eucalyptus leaves (toxic to most animals).
- Has a strong sense of smell and hearing.
- Gives birth to tiny, undeveloped young that crawl into the mother’s pouch.
- Young stay in the pouch for about 6 months.
- Slow-moving and sleeps up to 18 hours a day.
- Not a bear despite its name — it is a marsupial.
---
3. Third Image: Elephant
-
Type: Placental Mammal
(Placental mammals have a placenta that nourishes the developing fetus during pregnancy.)
-
Characteristics:
- Largest land animal on Earth.
- Long trunk used for breathing, smelling, touching, grasping, and producing sound.
- Large ears help regulate body temperature.
- Herbivorous — eats grass, bark, fruits, and leaves.
- Highly intelligent with complex social behaviors.
- Long gestation period (about 22 months).
- Give birth to live young.
- Found in Africa and Asia.
- Known for memory and emotional intelligence.

This worksheet helps students understand the diversity of mammals by classifying them into major groups:
monotremes,
marsupials, and
placentals, based on reproductive methods and physical traits.
Parent Tip: Review the logic above to help your child master the concept of mammal characteristics worksheet.
