Introduction to chelonian (turtle) medicine (Proceedings)
August 1, 2011

Turtles are found throughout the world on all continents and in all oceans except Antarctica. There are over 300 species of turtles (far fewer than snakes or lizards) that belong to about 90 genera in 13 families (http://www.reptile-database.org/db-info/SpeciesStat.html; accessed 7/09).

Diagnostic and clinical techniques for turtles (Proceedings)
August 1, 2011

Turtles appeared in the fossil record over 200 million years ago and were on earth long before mammals and other forms of present day reptiles. They occur in terrestrial, freshwater aquatic, semiaquatic, and marine environments.

Introduction to invertebrate medicine (Proceedings)
August 1, 2011

Invertebrate animals comprise 95% of the animal kingdom's species, yet non-parasitic invertebrates are vastly underrepresented in the typical veterinary school curriculum. These notes and the accompanying lecture provide a brief introduction to some of the more prominent invertebrate groups (coelenterates, mollusks, crustaceans, echinoderms, insects, the horseshoe crab, and spiders) and review the state of the science with regards to clinical techniques.

Introduction to pet fish medicine and surgery (Proceedings)
August 1, 2011

The group of animals commonly referred to as "fish" is a paraphyletic group of some 30,000-plus described species (www.fishbase.org). That is, it includes all of the descendants of the common ancestor of the vertebrates (subphylum Vertebrata) with the exception of the tetrapods (subclass Tetrapoda–amphibians, reptiles, birds, mammals, totaling around 23,000 species), a fairly significant branch of the subclass Sarcopterygii alongside lungfish and coelacanths.

A veterinarian's role in the 2010 gulf oil spill (Proceedings)
August 1, 2011

A mid-morning e-mail query from Dr. Craig Harms alerted me to the possibility of impending deployment to the Gulf of Mexico area for oiled sea turtle triage, treatment, and rehabilitation. Apparently the veterinary support for the Audubon Nature Institute's effort was about to head home and a relief team was needed pronto to provide clinical continuity.

Introduction to reptile medicine (Proceedings)
April 1, 2010

There are about 3100 species of snakes throughout the world. Only the Arctic regions, Antarctica, Iceland and Ireland, along with a few other very small oceanic islands lack the presence of snakes.

Pet fish medicine and surgery (Proceedings)
April 1, 2010

These notes are provided as an outline and brief review of pet fish medicine with emphasis on the clinical work up and standards of care.
