To examine the means whereby dragons produce fire and steam, we have studied a related species, the desert-lizard Lacerta pyrophorus. Morphological studies showed that there were in the snout three distinctive features: (1) a dorsal swelling in the pharynx, the Organ of Feuerwerk, consisting of brown adipose tissue with an extensive sympathetic innervation; (2) greatly enlarged lachrymonasal du...

The European common lizard Lacerta vivipara, a reptile of cold-temperate climates, provides us an interesting model of low-temperature adaptation. Indeed its unique cold-hardiness strategy, which employs both freeze tolerance and freeze avoidance, may be seen as the primary reason for its large distribution, which extends from Spain to beyond the Arctic circle. To study the metabolism supportin...
