Permanent slides ensures preservation of the body parts of the tiny aquatic animals and also also aids good visualization.Most of the exoskeleton of these tiny animals are lost during temporary slides preparation, thus loss of visualization.
Because the animals are transfixed to a point, their body parts can not be moved.
It also saves time, energy and resources spent during observation.
However,because of dehydration during preparation their natural color may be lost which may affect observation of natural features
