Watching animals eat is like my biology crack. I don’t need it, I don’t have to do it, I don’t even always like it, but there’s just something about critters noshing on one another that leaves me gobsmacked. And nothing does it like the comb jelly Beroe [Thread 🧵] 📽️ www.youtube.com/watch?v=1xkN...

To put this a bit into context for the layman: why is it important to clarify spider systematics? Because the classification of animals is the basis for identifying and comparing species and their traits. From ecological surveys to correctly identifying pest species in agriculture. 1/2

A spider that catapults ants into its web! “The snare mechanism seems to have evolved as a highly specialized way of allowing the spider to ‘pick off’ potentially hazardous prey one at a time and transport them a safe distance away from ant trails and nests.” @wolffspider.bsky.social

Wow, our ballista spider study was literally catapulted across the media, e.g. BBC, ABC, CNN, New York Times, New Scientist, Spiegel and a lot of regional newspapers, radio and tv stations. We were also highlighted by Nature: www.nature.com/articles/d41...

Biggest spider web in the world: the area of a flat. Found in a sulphur-smelling cave in the Balkans, this ~100m² spongy web is maintained by two species of solitary 🕷️. The 110K inhabitants feed on midges, probably because they can't see the other spiders. 🧪 subtbiol.pensoft.net/article/1623...

Spiders possess multiple types of silk glands, which produce silk materials with contrasting properties. What happens if they combine different silks into a single line - Does this reinforce, even toughen, the silk thread? We got some answers from cellar and cave spiders: doi.org/10.1039/D5SM... 🔓

Netcasting spiders modulate silk thread stiffness via a tailorable multi-fibre meta-structure to construct a web that is hyperelastic and high load-bearing at the same time. Read about our discovery in PNAS: doi.org/10.1073/pnas... 🔓 & with video content!
Figure showing a video still from a high speed video of a netcasting spider capturing a cricket with its elastic web held in the front legs. Left to the video still there are load-strain diagrams of different lines in the web showing that the upper lines are stiff and strong and the lower lines are highly extensible. Left to the diagrams there are scanning elactron microcopy images of the dfifferent lines, showing that the upper, stiffer lines are cables made of many parallal fibres, whereas the lower lines have a soft central core with adjoined looped fibres. The degree of looping correlates with how much the spiders post-process the silk after spinning. This way they can tailor the stiffness of each line in the web separately and create a vertical stiffness gradient throughout the whole web architecture from stiff and strong in the upper load bearing frame to soft and hyper-elastic in the lower part that is rapidly extended and thrown against the prey at high speed during the predatory strike.

This is the Sunburst Candy Spider from Thailand. Not AI (sucks to have to declare this). Very real and had been on my wish list for a long time. The taxonomic placement is unclear, so we are leaving it at Cyrtarachninae.

This is a "reindeer cyclone", a defensive behavior that has been observed in herds of reindeer, even in captivity. The fawns and older animals are at the center, the strongest animal in the outer lanes. The point is to confuse the brains of predators accustomed to stalking a single outlier.
