Dwarf crocodiles build mound nests, in which they lay 10-14 eggs early in the wet season. Necropsy revealed a vegetative valvular lesion of the left atrioventricular valve, miliary foci of necrosis in the endocardium and myocardium, multiple .

A clear size difference is observed in same-age animals between the runts and the otherwise healthy ones. The pubo-ischio-femoral nerve can be analogous to the ischiadicus nerve described in other vertebrate species, mainly considering their innervation territories (laterocaudal surface and muscles of the thigh, including the flexor muscles of the tibia and the pelvic muscles, with the exception of the obturator nerve's territory).

O. t. tetraspis has lighter colours, a more pointed, upturned snout, and more body armour than O. t. osborni. Because they are ectotherms, the core body temperature of reptiles is more prone to fluctuate than that of mammals or birds. In a different study, yeasts were isolated from swabs of the oral cavity and cloaca in 40.2% of reptile patients that were cultured.33 Candida species and Trichosporon species were most frequently isolated, but Torulopsis and Rhodotorula species were also present. 1 MEDIA REPRESENTING PHYSICAL OBJECT .

Because the previous evidence supports the concept that spores are omnipresent and unavoidable both on and within healthy reptiles, to infer that host response to fungal invasion is the key to the outcome of fungal spore–reptile interaction appears logical. [18] Foraging is mainly done in or near the water, although it is considered to be one of the most terrestrial species of crocodilian and may expand the feeding pattern to land in extensive forays, especially after rains. Hunting locations and methods determined the types of species entering bushmeat markets while selling conditions and prices determined whether species were traded locally or in urban markets.
