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.
