Highlights•We compared leatherback and loggerhead hatchlings' phototaxis responses.•
Leatherbacks were less sensitive to wavelengths of 340–580 nm than loggerheads.•Under …

Sea turtle hatchlings emerge from underground nests on oceanic beaches, crawl to the
ocean and swim out to sea. The primary cue used to find the ocean from the nest is the …

When emerging from the nest, sea turtle hatchlings primarily orient using visual stimuli, with
light pollution known to disrupt effective sea localization behavior. Previous studies have …

Sea finding behaviour in hatchling sea turtles is widely believed to be guided by orientation
towards the brightest horizon and away from high silhouettes. We propose that the horizon …

Upon emerging from underground nests, sea turtle hatchlings immediately crawl toward the
ocean. The primary cues used in orientation are visual but the nature of the visual cues was …

Hatchling sea turtles (Caretta caretta) emerge from their beach nests at night and crawl
seaward immediately, even where the sea is not visible to them. This sea-finding ability of …

When moving from the nest to the sea, hatchling leatherback turtles, Dermochelys coriacea,
sometimes turn completely around and then continue forward. These orientation circles …

Visual cues are important to sea turtle hatchlings in determining seaward direction upon
emerging from the nest. In this study, we examined the roles that color and intensity play in …

Within minutes after emerging from underground nests, sea turtle hatchlings Caretta caretta
L. locate and crawl to the ocean, enter the surf, then maintain oriented courses that lead …

Studies were undertaken to determine the timing and photic nature of sea-finding behavior
in hatchling sea turtles leaving the nest, and how anthropogenic lighting disrupts this ability …
