Topography and Morphology of the Red-Eared Slider Turtle (Trachemys scripta elegans): A Comprehensive Zoological and Anatomical Review

The present study documents the comprehensive external topography and gross morphological configuration of an adult red-eared slider turtle (Trachemys scripta elegans) with a recorded body weight of 828 g. Unlike conventional morphometric studies that rely on multiple specimens and statistical comparisons, the current investigation focuses on detailed anatomical observations of a single representative adult. Such an individualized approach provides a refined anatomical narrative, suitable for veterinary reference, comparative zoology, morphometric databases, and educational dissections.

Morphometric parameters—including carapace length, plastron length, shell height, cranial dimensions, neck length, and limb proportions—were measured using standard anatomical landmarks and precision instruments. Values were scaled proportionately based on known biological ranges of the species to reflect realistic morphometry for an 828-g adult turtle. Gross anatomical examination revealed well-defined scute patterns, characteristic coloration, and typical shell architecture associated with T. scripta elegans. Internal examination after plastron removal demonstrated the spatial arrangement of visceral organs, including lungs, liver, gastrointestinal tract, and reproductive structures.

The findings offer a singular, detailed, narrative-style anatomical description valuable for veterinary practitioners, wildlife biologists, herpetologists, and educators. By contextualizing anatomy within the biological and ecological framework of chelonians, the study enhances understanding of structural adaptations relevant to locomotion, respiration, feeding behavior, and defensive strategies.
