It’s easy to think that the globe’s vast oceans would be effective barriers to the movement of land animals. An elephant can’t swim across the Pacific, after all. But it turns out that plenty of plants and animals have unintentionally floated across oceans from one continent to another. Now comes evidence that tiny, trapdoor spiders (蜘蛛) made such a journey millions of years ago.
Moggridgea rainbowi spiders can be found on Kangaroo Island, which sits off the south coast of Australia. These spiders build a silk-lined hole in the ground, notes Sophie Harrison, a biologist in Australia. The hole and trapdoor provide these spiders with shelter and protection. It also provides them an out-of-sight spot from which to wait for approaching creatures.
There is evidence, though, that the ancestors of them might have traveled millions of meters to get to Australia from Africa. That isn’t as unlikely as it might at first seem. Australia used to be connected to other continents, long ago, as part of a supercontinent called Gondwana. And humans have been known to transport species all over the planet. But there’s a third option. The spiders might have rafted (乘筏) long distances across the sea.
To figure out which story was most likely true, Harrison and her colleagues looked at the spider’s genes. They looked at the genes in seven Moggridgea rainbowi spiders from Kangaroo, and five species of Moggridgea spiders from South Africa. The Australian and African spiders split off from a common ancestor some 2 million to 16 million years ago, the genes showed.
If a large swatch of land washes into the sea, filled with arachnids (蛛形纲动物), the spiders may be able to hide themselves throughout the journey. Plus, they can “hold their breath” and survive on stored oxygen during periods of temporary flooding, the researchers note.
