Something keeps insects out of the open ocean, and it isn’t the pressure of the deep
3+ week, 2+ day ago (1256+ words) Fly larvae in one African lake sink deep down into oxygen-free water every morning, with their air sacs tolerating crushing pressures. Insects live nearly everywhere on land and in fresh water. Underwater in the open sea, there are none. One…...
New hairy-leafed plant species confirms another of Darwin’s predictions
4+ week, 9+ hour ago (986+ words) Saxifraga candelabrum is a newly confirmed carnivorous plant. Its sticky hairs trap small insects, while its flowers attract them with scent. Carnivorous plants are famous for dramatic traps, but catching an insect is only part of the story. To qualify…...
