The Aloha State is famous for, well, its spirit of aloha -- you can feel it in the tropical breezes and sense it in the warm and welcoming people. But not everything is welcomed warmly here.

Take the giant poisonous plant that has recently been found spreading throughout Kauai. The Bingabing tree, which is already well established on Oahu and the Big Island, has huge leaves and forms dense thickets that shades and chokes out any surrounding plants. Spreading of these trees could threaten the Garden Island's beloved plant diversity and possibly turn the whole island into a Bingabing forest.

But gigantic leaves aren't Hawaii's only invasive problem. As the most isolated land mass on Earth, most of the native plant and animal population evolved without many of the world's more competitive and predatory species. In short, Hawaii's native species are more gentle than others, leaving them vulnerable to the "meaner" species that are only just being introduced to the islands.

So, who are these meanies? Meet the culprits below.
