* Species Variation: There are seven species of sea turtles, and each has different nesting habits, clutch sizes, and survival rates for hatchlings.
* Nesting Locations: Nesting numbers fluctuate greatly depending on the location and environmental conditions.
* Predation and Survival: A significant number of eggs and hatchlings are lost to predators (like crabs, birds, and mammals) and natural hazards.
* Data Collection: While scientists monitor nesting beaches, tracking the exact number of offspring produced globally is a difficult task.
Instead of a specific number, here's what we can say:
* Millions: Sea turtles lay millions of eggs every year, but only a small percentage survive to adulthood.
* Population Trends: Sea turtle populations are under threat due to habitat loss, pollution, and fishing bycatch.
If you're interested in specific numbers for a particular species or region, you can look up information from organizations like:
* Sea Turtle Conservancy: https://www.conserveturtles.org/
* WWF: https://www.worldwildlife.org/
* NOAA: https://www.fisheries.noaa.gov/
Remember, even with estimates, the numbers can change drastically from year to year.
