People on a beach in southern California saw a tropical sea turtle lay eggs in the sand. A few days later, a second sea turtle also laid eggs on another beach nearby. Scientists say this is the first time sea turtles have nested on the west coast of the United States.

a few days later= 在幾天之後

These turtles are olive ridley sea turtles. They usually lay their eggs much further south in warm places like Mexico and Central America. Nesting means crawling onto the beach to build a nest and lay eggs.

Scientists do not know exactly why the turtles came to California. The ocean water is getting warmer, which can bring tropical animals to new areas. A recent storm or ocean current might also have pushed the turtles off course. Scientists will watch to see if more turtles arrive.

might also have pushed= 用來表示對過去發生的動作或原因推測「也可能已經…」

Local workers built fences around the turtle nests to keep the eggs safe from wild animals and high ocean waves. Wildlife experts tell people to stay at least 50 feet away from any sea turtle on the beach so the animals stay safe.

at least= 至少(不少於特定數量或距離)

延伸學習

  • •欖蠵龜(Olive ridley sea turtle)通常在熱帶地區的海灘進行大規模集體產卵(稱為 arribada)。
  • •加州沿岸的海水通常對熱帶爬蟲類來說過於寒冷,因此在這麼偏北的地點出現產卵行為,是海洋水溫變化的一個顯著指標。
