While collecting specimen for observation, a biologist should play close attention to the following:
Collect only the number of specimen you need; do not collect more than you need.
Do not harm the specimen during the capture/collection exercise.
Do not destroy the natural habitat of the specimens.
Handle dangerous/injurious specimens with care. Such injurious specimens can be stinging plants or insects. Forceps and hand gloves should be used in such cases.
