Vertebrates have complex morphologies, thus, specimens need to be preserved for long term examination. Mostly, the whole specimens are preserved in solution. However, skins, skeletons, skulls and tooth are very important parts using to indentify vertebrates, therefore, these particular parts can be preserved separately.

Fish Collection

Curator: Asst.Prof.Dr.Vachira Lheknim

Ichthyology collection gathers freshwater, blackish and marine fishes. Most specimens came from research projects of lecturers in the Department of Biology. Originally, the specimens were preserved in formalin solution. However, due to its toxicity, the newly collected specimens will be preserved in 70% ethanol. The old specimens are gradually transferred from formalin to ethanol. The ichthyology collection is located on the 1st floor of the museum building. This collection housed 3,000 specimens of 880 fish species, accounting for 41% of fish species found in Thailand1

The majority of specimens are preserved in 70% ethanol; in addition, there are also preserved skeletons and skins. The collection stores 1,376 specimens from 83 amphibian species, accounting for 59% of amphibian species in Thailand2, and 613 specimens of 148 reptile species, accounting for 46% of reptile species in the country3. Among these, there are type specimens of Boonsong’s Bent-toed Gecko (Cyrtodactylus lekaguli Grismer et al, 2013) and Starry Bent-toed Gecko (Cyrtodactylus astrum Grismer et al, 2013).
