Crocodilians (Crocodylia)

2022
This chapter focuses on crocodilians, including alligators and caimans. The Spectacled Caiman is a medium-sized alligatorid species. Although very wary by nature, it can nonetheless be a dangerous animal under the wrong circumstances. Populations of the Spectacled Caiman in the United States were derived from the pet trade.

Convergent evolutionary shifts in rhodopsin retinal release explain shared opsin repertoires in monotremes and crocodilians

Proceedings of the Royal Society B: Biological Sciences, 2023
The visual ecology of early mammals remains poorly resolved. Studies of ancestral photopigments suggest an ancient transition from nocturnal to more crepuscular conditions. By contrast, the phenotypic shifts following the split of monotremes and therians—

Are Seeds Consumed by Crocodilians Viable? A Test of the Crocodilian Saurochory Hypothesis

Southeastern Naturalist, 2014
Abstract Many animal species are important dispersers of seeds; however, relatively little attention has been paid to the seed-dispersal capabilities of reptiles, and almost nothing is known about the seed-dispersal capabilities of crocodilians. This lack of information is surprising given that seeds have been found in the stomach contents of a ...

Human dimensions of crocodilians: a review of the drivers of coexistence

Human Dimensions of Wildlife, 2021
Crocodilians are socially and ecological important apex predators. Yet, many societies struggle to share space with crocodilians, especially in urban and coastal regions.

At the Crocodilian Heart of the Matter

Science, 2000
The interpretation of the haemodynamics of the crocodilian heart by Fisher et al. in their report “Cardiovascular evidence for an intermediate or higher metabolic rate in an ornithischian dinosaur” (21 Apr., p. [503][1]) is flawed and hence casts doubt on their conclusion that dinosaurs had “
