巢的温度决定了幼龟的性别。在30°C时,雄龟和雌龟的比例相等。在较高温度下,女性受到青睐。在较低温度下,男性受到青睐。大约80天后,幼龟通常在夜间将自己从巢中挖出来,并前往更明亮的海浪。一旦进入水中,log龟就会在脑中使用磁铁矿和地球的磁场进行导航。世界自然保护联盟红色名录将红海龟分类为“易受攻击”。人口规模正在减少。由于高死亡率和缓慢的繁殖率,这一物种的前景并不好。人类直接或间接地威胁到海龟和其他海龟。虽然世界范围的立法保护海龟,但在没有执法的情况下,他们的肉和蛋被消费。许多海龟死于兼捕或淹没在渔线和渔网中。塑料对log鱼产生了重大威胁,因为漂浮的袋子和床单类似于水母,一种受欢迎的猎物。塑料可导致肠道阻塞,加上它会释放出有害化合物,破坏组织,薄蛋壳或改变龟的行为。人类侵占造成的栖息地破坏剥夺了筑巢的海龟。人工照明会困扰幼龟,干扰它们找水的能力。发现幼龟的人可能会试图帮助他们上水,但这种干扰实际上会降低他们生存的机会,因为它会阻止他们建立游泳所需的力量。气候变化是令人担忧的另一个原因。由于温度决定了孵化性,温度上升可能会使性别比例偏向于女性。在这方面,人类的发展可能有助于海龟,因为高层建筑遮蔽的巢穴更凉爽,产生更多的雄性。

The temperature of the nest determines the sex of the young turtle. At 30 ° C, the ratio of male to female turtles is equal. At higher temperatures, women are favored. At lower temperatures, men are favored. After about 80 days, the young turtles usually dig themselves out of the nest at night and head to the brighter waves. Once inside the water, the log turtle uses the magnetite and the Earth’s magnetic field to navigate through the brain. The IUCN Red List classifies red sea turtles as “vulnerable”. The population size is decreasing. The prospects for this species are not good due to high mortality and slow reproductive rates. Humans directly or indirectly threaten sea turtles and other sea turtles. Although worldwide legislation protects sea turtles, their meat and eggs are consumed without law enforcement. Many sea turtles die from bycatch or submerged in fishing lines and fishing nets. Plastics pose a major threat to log fish because floating bags and sheets are similar to jellyfish, a popular prey. Plastic can cause intestinal blockage, plus it can release harmful compounds, destroy tissue, thin eggshells or alter the behavior of the turtle. Habitat destruction caused by human encroachment deprives the nesting turtles. Artificial lighting can plague young turtles and interfere with their ability to find water. People who find young turtles may try to help them get into the water, but this interference actually reduces their chances of survival because it prevents them from building the power they need to swim. Climate change is another cause for concern. Since temperature determines hatchability, an increase in temperature may bias the sex ratio toward women. In this regard, human development may contribute to sea turtles, because the nests covered by tall buildings are cooler and produce more males.
