Predict + reason
Read the scenario carefully, then answer the questions below using scientific evidence from the lesson.
Scenario
A new animal is discovered in the rainforests of Far North Queensland. Scientists observe that it has moist, smooth skin with no scales. As a larva it lives in water and breathes through gills. When it matures, it moves onto land and breathes using lungs — but it must return to water to lay its eggs.
(a) Predict: Which vertebrate class does this new animal belong to? Write your prediction clearly.
(b) Justify: Give at least two pieces of evidence from the scenario that support your prediction. Use scientific terms from the lesson.
1. A student says the platypus cannot be a mammal because it lays eggs. Do you agree? Explain using evidence from what you know about mammals.
2. A blue-ringed octopus lives in the ocean and is a predator. Explain why it is classified as an invertebrate mollusc rather than a fish, using two features of its body.
