Sea turtles are more than just slow-moving ocean wanderers — they carry millions of years of history and fascinating science with them.

Today, let's explore 5 more incredible turtle facts (if you missed the first half, let me know and I'll fill you in!). Some of these may just blow your mind.

Temperature Decides If It's a Boy or Girl

Here's something you probably didn't learn in school: sea turtle eggs don't rely on genes alone to decide if they hatch as male or female — it depends on temperature. Yes, the warmth of the sand where the eggs are buried can literally shape the future of turtle populations.

If the nest is warmer (closer to the sun, less rainfall), more females will hatch. If it's cooler, there'll be more males. Even the position of the egg in the nest plays a role — eggs in the center stay warmer and tend to produce females, while eggs near the edges often become males. This means rising temperatures from climate change could seriously tip the balance!

They Travel Unbelievable Distances

We love a good journey, and turtles are right there with us. Some species of sea turtles travel thousands of miles between where they feed and where they lay their eggs. For example, one leatherback turtle was tracked swimming over 12,000 miles from Indonesia to the U.S. west coast!

Turtles have an incredible sense of direction and seem to remember their nesting beaches no matter how far they roam. It's like they have a built-in GPS that never fails.

They Live a Long, Long Time

If we think about longevity in the animal world, sea turtles definitely make the list. Most types of sea turtles don't reach adulthood quickly — it can take 20 to 30 years for them to mature. But once they do, they can live up to 70 or even 80 years.

It's this slow-growing nature that makes protecting them extra important. When a turtle lives this long, every egg and every safe beach really counts.

Turtles Have Been Around Since Dinosaurs

Want to feel tiny in the timeline of life? Sea turtles have been cruising through Earth's oceans for over 200 million years! The first turtle-like creatures popped up even before the dinosaurs walked the Earth.

One of the earliest known sea turtles, Odontochelys, lived around 220 million years ago. Unlike today's turtles, it actually had teeth — which sounds kind of scary, right?

Many Sea Turtles Are Now in Danger

Out of the seven sea turtle species that exist today, six are considered at risk. That's a huge red flag for us. Their troubles come from things like:

• Coastal construction (which wipes out their nesting areas)

• Getting caught accidentally in fishing gear

• Eating or getting stuck in ocean trash

• Boat traffic injuries

• Climate change affecting their nesting and food sources

But we can help, Lykkers! Here are a few things we can do:

• Support turtle conservation groups, even small donations make a difference

• Use reusable items to cut down on trash in the ocean

• Choose seafood that's harvested responsibly

• Never buy products made from turtles (like their shells or eggs)

• Watch out for turtles if you're out on the water

• Lower our energy use to help slow climate change

We're All Part of Their Survival

Lykkers, sea turtles might have survived for millions of years, but their future now depends on us. These amazing creatures have seen the rise and fall of dinosaurs, crossed entire oceans, and lived for decades — yet they need our help more than ever.
