- Discovering Species
- Predictions of the number of undiscovered species are based on past rate of discovery
- Reasons for undiscovered species
- Ecosystems are too inaccessible to fully research e.g. deep sea
- Species have similar appearance, structure and behaviour
- DNA identification methods helping tell species apart
- Males and females can look different and live alone
- Many plants can only be identified while flowering
- Less than 2 million species have been identified
- An estimate of 5-100 million species remain undscovered
