The skins of crocodylids and gavialids can be distinguished from those of alligatorids by the presence of darkly pigmented pits, known as integumentary sense organs (ISOs), on the postcranial scales. The structure of ISOs, in Crocodylus porosus, was studied using light microscopy and scanning and transmission electron microscopy. The stratum corneum of the epidermis in the area of the ISO is thinner, while the stratum germinativum is thicker, relative to other regions of the integument. Beneath… 

Histology, ultrastructure, and pigmentation in the horny scales of growing crocodilians

The present morphological study describes the color of hatchling, juvenile, and adult crocodilian skin and the origin of its pigmentation and determines the brown or the light yellow-orange background observed among the darker regions of crocodilian scales.

General morphology of the oral cavity of the Nile crocodile, Crocodylus niloticus (Laurenti, 1768). I. Palate and gingivae.

The heads of nine 2.5 to 3-year-old Nile crocodiles were obtained from a commercial farm where crocodiles are raised for their skins and meat and both regions showed a presence of Pacinian-type corpuscles.

Structure, innervation and response properties of integumentary sensory organs in crocodilians

It is concluded that crocodilian ISOs have diverse functions, including detection of water movements, indicating when to bite based on direct contact of pursued prey, and fine tactile discrimination of items held in the jaws.

Crocodylians evolved scattered multi-sensory micro-organs

The ancestral vertebrate diffused sensory system of the skin was transformed in the crocodylian lineages into an array of discrete multi-sensory micro-organs innervated by multiple pools of sensory neurons, resulting in a highly-armored, but very sensitive, skin.

Ultrastructural evidence of a mechanosensory function of scale organs (sensilla) in sea snakes (Hydrophiinae)

It is concluded that the scale organs of marine hydrophiines have retained a mechanosensory function, but future studies are needed to examine whether they are sensitive to hydrodynamic stimuli.

The evolution of scale sensilla in the transition from land to sea in elapid snakes

Assessment of morphological variation in sensilla on the postocular head scale(s) across four terrestrial, 13 fully aquatic and two semi-aquatic species of elapids represents the first analysis of the evolution of sensilla in the transition from terrestrial to marine habitats.

Functional Microanatomy of the Feather-Bearing Integument: Implications for the Evolution of Birds and Avian Flight1

Evidence is presented for the fact that the ancestral birds were probably small, arboreal, hopping, and using flap-bounding, or intermittent bounding, flight and the critical role that a streamlined body plays in avian flight is likely to have played in the evolutionary transformations.

Functional Microanatomy of the Feather-Bearing Integument: Implications for the Evolution of Birds and Avian Flight

A selective regime favoring a streamlining of body contours and surfaces is proposed as having been instrumental in driving the morphological and functional transformations of an unfeathered

Crocodilian behaviour: a window to dinosaur behaviour?

While individual crocodilian species have adapted their behaviours to meet specific strategies for survival in specific habitats, core reproductive behaviours are universal among modern crocodilians and transcend speciation, morphology and geographic distribution.



A comparison of the epidermis and pigment cells of the crocodile with those in two lizard species

The greater uniformity in histological structure and in distribution of chemical substances throughout the depth of the crocodile stratum corneum was in marked contrast to the lizards, which showed morphological differences, and differences in intensities of chemical reactions in the horny cells laid down early and late in each keratinization cycle.

Ultrastructural organization of avian stratum corneum lipids as the basis for facultative cutaneous waterproofing

It is concluded that birds, whose homeothermic control depends so much on CWL, cannot possess a permanent “good barrier,” as such would compromise the heat loss mechanism.

Morphological and biophysical identification of fibrous proteins in the amniote epidermis.

It has been found that morphologic and/or tinctorial properties are not good criteria for the identification of specific fibrous protein types in reptilian epidermal material.

Habitat and phylogeny influence salinity discrimination in crocodilians: implications for osmoregulatory physiology and historical biogeography

This study investigated whether the ability to discriminate between hyper- and hypo-osmotic salinities is determined by habitat, as it is in other normally freshwater reptiles, or whether, like morphological adaptations associated with estuarine life, it has a phylogenetic basis.
