| Specimen Preparation | Larger spp can be identified living, but smaller spp need appendages mounted. Fine tingsten needles are recommended for the diessection. These can be made by dipping the end of a short length of tungsten wire (c.0.2mm thick =No. 35 or 36 S.W.G.) in hot molten sodium nitrite. The latter can be heated over a spirit lamp in a very small brass or iron container in a well-ventilated space (danger: don’t spill or touch the molten liquid). When the nitrite is hot enough the end of the wire will glow and erode to leave an extremely sharp point. The wire can be glued to a matchstick for easier handling. |
| Identification difficulty | Larger spp are straightforward, but Microcyclops are tricky. |
