Praying Mantises: More Badass Than We Knew

‘Praying mantises are among the most frightening insects on the planet, equipped with powerful front legs which they use to snatch unwary insects, spiders, and even the odd amphibian or reptile. But as new research reveals, praying mantises are also proficient at capturing birds—which they do more often than we thought.

New research published in The Wilson Journal of Ornithology shows that small birds often fall victim to praying mantises, and that this behavior exists among many different mantis species around the world. Most cases of this insect-on-bird violence were documented in North America, where small birds—particularly hummingbirds—are snatched by the predatory insects when visiting feeders or house gardens…’

So we ought to call them “preying mantises”??

Rogue wave holes

now-b1594826-4da8-43c7-83fd-511cdae7f4da-1210-680I have long been fascinated by rogue waves, finding them to be the stuff of nightmares (literally; as a child I had recurring dreams about being in the path of one). Well, now it appears there are rogue troughs as well:

‘Rogue waves in the ocean can take two forms. One form is an elevated wall of water that appears and disappears locally. Another form is a deep hole between the two crests on the surface of water. The latter one can be considered as an inverted profile of the former. For holes, the depth from crest to trough can reach more than twice the significant wave height. That allows us to consider them as rogue events. The existence of rogue holes follow from theoretical analysis but has never been proven experimentally. Here, we present the results confirming the existence of rogue wave holes on the water surface observed in a water wave tank …’
