Stabilizing the Critical Small Exotic Mammal Exotics & Reptile Patient

Special Needs for the Exotic Small Mammal and Reptile Patient In general, basic equipment used for dogs and cats can be used on many exotic small mammals and reptiles. Most exotic animal patients tend to be very little; therefore pediatric equipment is a must. It is important to have catheters and needles as small as 26g. Small uncuffed endotracheal tubes should be available, and 18g to 14g IV ...

Heart mitochondrial properties and aerobic capacity are similarly related in a mammal and a reptile.

The heart mitochondrial properties and the aerobic capacity (VO2max) of the rat (Sprague-Dawley breed) and the Cuban iguana (Cyclura nubila) were used to evaluate the relationship between the oxidative capacity of the heart and the maximum oxygen delivery rate. Both species are active at body temperatures of 37-39 degrees C, have similar heart mitochondrial volumes [Vmt; 0.43 +/- 0.02 ml (S.E.M...

Mammal-like occlusion in conodonts

—Conodont element function and feeding mechanisms are of considerable paleobiological importance, yet many details remain poorly understood and speculative. Analysis based on morphology, physical juxtaposition, and patterns of surface damage and microwear on pairs of Pa elements from individuals of Idiognathodus indicates that these elements crushed food by rotational closure, which brought the...

Eutherian-like reproductive specializations in a viviparous reptile.

The viviparous Brazilian scincid lizard Mabuya heathi exhibits a suite of reproductive specializations widely believed to be confined to the eutherian mammals. This skink ovulates the smallest known reptilian egg ( approximately 1.0 mm in diameter). Placental transport accounts for >99% of the dry mass of the periparturient fetus, representing a degree of placentotrophy proportionately greater ...
