Ontogenetic investigation of underwater hearing capabilities in loggerhead sea turtles (Caretta caretta) using a dual testing approach.
Sea turtles reside in different acoustic environments with each life history stage and may have different hearing capacity throughout ontogeny. For this study, two independent yet complementary techniques for hearing assessment, i.e. behavioral and electrophysiological audiometry, were employed to (1) measure hearing in post-hatchling and juvenile loggerhead sea turtles Caretta caretta (19-62 c...
متن کاملFirst report of the epizoic red alga Polysiphonia carettia (Hollenberg, 1971) on the loggerhead turtle Caretta caretta in the Adriatic Sea
Sea turtles are widely distributed in temperate and tropical seas, and their carapace is often colonized by species of macroalgae. There have been several studies on the epibionts of loggerhead turtles, Caretta caretta Linnaeus, from different parts of the world (KITSOS, et al., 2005; PFALLER et al., 2006, 2008). The carapaces of loggerhead turtles represent an important substratum for a variet...
متن کاملCarapace epibionts of loggerhead turtles (Caretta caretta) nesting at Canaveral National Seashore, Florida
A survey of the epibionts inhabiting the carapace of loggerhead sea turtles Caretta caretta (Linnaeus) nesting on Canaveral National Seashore, Florida was conducted from 2003–2004. Epibionts were sampled and identified to the lowest taxonomic level possible. Eleven newly documented epibiont species were observed from 52 individual loggerheads. We present the first records of sea urchins as logg...
متن کاملThe ontogeny of morphological defenses in Kemp's ridley (Lepidochelys kempii) and loggerhead (Caretta caretta) sea turtles.
Marine turtles are large reptiles that compensate for high juvenile mortality by producing hundreds of hatchlings during a long reproductive lifespan. Most hatchlings are taken by predators during their migration to, and while resident in, the open ocean. Their survival depends upon crypticity, minimizing movement to avoid detection, and foraging efficiently to grow to a size too difficult for ...
متن کاملBaseline plasma corticosterone, haematological and biochemical results in nesting and rehabilitating loggerhead sea turtles (Caretta caretta)
The evaluation of hormonal responses to stress in reptiles relies on acquisition of baseline corticosterone concentrations; however, the stress associated with the restraint needed to collect the blood samples can affect the results. The purpose of this study was to determine a time limit for the collection of blood samples to evaluate baseline corticosterone, haematological and biochemical res...
