Inside the herpetology collection
A jar of snake specimens
Most of the museum's reptile, amphibian and fish specimens are kept in jars, along with ethanol to preserve them. These collections contain nearly one million specimens that provide vital information to biologists doing research in areas ranging from evolutionary patterns to locomotion to conservation. Here are some interesting facts about our collections:
1.We try to keep the fluid collections in relative stasis in regard to temperature and humidity. The goal is 65 degrees F and 50% relative humidity. In practice, however, the temperature is fairly steady but the relative humidity varies quite a bit.
2.The oldest specimen in the herpetology collection is Ceratophrys aurita, KU 98129, collected in Brazil in 1863. It, however, is an exchange specimen. The oldest specimen collected by a museum affiliate is a Thamnophis elegans from New Mexico, KU 2408, collected in 1880. The oldest specimens collected in Kansas are two copperheads and a massasauga from Franklin county in 1888. The history of specimen collecting for these collections has been steady ever since. There are 60 specimens collected prior to 1900.
3.The specimen with catalogue number 'KU 001' is Alligator mississippiensis. The specimen is on display in the panorama at present for the Adopt-A-Specimen exhibit.
4.The sheer volume of ethanol used in the collection is impressive. We have a 1795 gallons for amphibians, and about 1875 gallons in large specimen tanks. The reptiles utilize about 1500 gallons. That's a 5,170 gallon capacity for reptiles and amphibians. Double that in fishes, and add a touch for the others. For everything together, 12,000 gallons total is a reasonable estimate. Of that, a substantial amount of space in the jars is taken by specimens and air, so we would actually have about 8,000 gallons of 70% EtOH (ethanol) in the wing. That's about 5,600 gallons of Ethanol (about 102 drums), significantly less than a typical residential swimming pool.
