Article Synopsis
- Olive ridley sea turtles exhibit two nesting behaviors: solitary nesting and mass nesting called "arribadas," which offers benefits like better mate finding and predator avoidance.
- A study revealed that turtles nesting in arribadas were larger, had higher thyroid hormone levels, and showed enriched metabolic processes related to energy use and antioxidant defense.
- However, arribada nesters also experienced higher oxidative stress indicated by increased lipid peroxidation and protein oxidation, suggesting a trade-off between the fitness benefits of mass nesting and associated physiological costs.

Ex-situ conservation in hatcheries is a successful strategy for the recovery of sea turtle populations. However, it alters the ontogenesis of the brain and gonads, as well as body size and locomotor performance at nest emergence. Relocation to hatcheries may alter immune system development, since this depends highly on the nest environment.

Olive ridley sea turtles exhibit polymorphic nesting behavior, mass nesting behavior called arribada, where thousands of turtles will nest at once, and solitary nesting behavior. The potential physiological differences between the individuals using these strategies are not well understood.
