Eatlemania

spective using a variety of animal models. But we have always taken a comparative and evolutionary anatomy approach to understanding how bones and muscles work. In order to study comparative bone and muscle anatomy and biomechanics, we have amassed a large collection of animal cadavers over the years. Many of these animals have been used to produce published data on bone and muscle form and function. A complete list of comparative anatomy references from our lab that have utilized these and other animals is listed below. We have been fortunate to obtain funding for our health-related research over the last couple of years which has crammed our freezers full of research animals waiting to be skeletonized and archived for use by other researcher and as teaching tools for our outreach initiatives. So naturally, we employ the most efficient laboratory workers for such a job: a colony of dermestid beetles who clean away all the soft tissue from our skeletal specimens for us. And we hope you will enjoy learning a little about each of the animals our beetles (aka The Eatles) are chomping on cleaning for us. Dermestid beetles (Dermestes maculatus), or hide beetles, feed on carrion and dried animal remains, and are the preferred method for cleaning skeletal remains at museums world wide. They only eat dried animal flesh, which means they have no interest in eating our hands while we handle them. Because they eat dried animal remains, they are also important indicators in forensic entomology as they typically arrive within a week after death and are one of the dominant insects in mid and late decay. You can read more about the geographic distribution, life cycle, and general biology of the dermestid beetle at the University of Florida's Featured Creatures website. Our first experiences with dermestid beetles occurred while working in the collections of the Smithsonian National Museum of Natural History. When we decided to start our own beetle colony, we scoured the interwebs looking for sources of beetles and advice for running a colony. We purchased our beetles from Kodiak Bones & Bugs Taxidermy, and we are grateful for their help in establishing our colony. We will update this blog each time we introduce a new set of remains to our colony. The goal will be to describe the animal species being cleaned and to detail a little of that species' natural history. Contributed by: Jason Organ, PhD
