Abstract
The chapter provides a concise account of collecting techniques, and basic histological techniques for investigating planarians, intended for use by practicing scientists and postgraduate students new to the field. Selected hands-on methods are described that will lead to well-stained preparations suitable for light microscopic examination for subsequent taxonomic identification or general investigations into planarian functional cytology and histology. Major equipment items that are minimal essential requirements of a functional histological laboratory are indicated. The chapter includes sectioning and staining troubleshooting guides that will be very helpful for those who must work in the laboratory without the opportunity to consult qualified and experienced technicians or microscopists.

Notes
- 1.
Chloral hydrate acts as a preservative and can be omitted. Add a few crystals of thymol as a preservative.
- 2.
Synonym: Crystal Ponceau 6R, available through SIGMA chemicals.
- 3.
Synonym: Aniline Blue WS. Methyl Blue (C.I. 42780) may be substituted for the Soluble Blue.
- 4.
The original method stated 10 min staining in Soluble Blue. This was found to be generally too long for land planarians.
