Animals use adhesive secretions in a plethora of ways, either for attachment, #egg anchorage, mating or as either active or passive defence. The most interesting function, however, is the use of adhesive threads to capture prey, as the bonding must be performed within milliseconds and under unsuitable conditions (movement of prey, variable environmental conditions, unfavourable attack angle, etc.) to be nonetheless successful. In the following study a detailed characterization of the prey capture system of the world-renowned #glowworm group Arachnocampa from the macroscopic to the ultrastructural level is performed. The data reveal that the adhesive droplets consist mostly of #water and display hygroscopic properties at varying humidity levels. The droplet core of Arachnocampa luminosaincludes a certain amount of the #elements sodium, sulphur and potassium (beside carbon, oxygen and nitrogen), while a different element composition is found in the two related species A. richardsae and A. tasmaniensis. Evidence for lipids, carbohydrates and proteins was negative on the histochemical level, however #X-ray photoelectron spectroscopy confirm the presence of peptides within the droplet content. Different to earlier assumptions, the present study indicates that rather than oxalic acid, urea or uric acid are present in the adhesive droplets, presumably originating from the gut. Comparing the capture system in Arachnocampawith those of orb-spiders, large differences appear not only regarding the silky threads, but also, in the composition, hygroscopic properties and size of the mucous droplets.#follow us @bioengr.ig#frog#animal#biology#kingdom#science#lab#elements#research#saliva#gland#green#nature#beautitul#awesome#news#instadaily#likecredit: skunkbear & plos
#mobiusff#weaponboost modification system — this is where you’ll be putting #skillseed long after unlocking your job panels. — each mod is done after 6 upgrades that consume skillseeds. — each mod cost 2x #crystal — a crystal costs 200 #magicite, or 1.35USD. you are awarded zillions of crystals throughout your travels in #palamecia , and they drop very rarely in normal combat. (( equip the ‘crystal hunter’ #autoability from the #magic#egg in the #itemstore#kupo! )) — if you tried to flat up buy 332 crystals (66,400 magicite, or 5.312 batches of 74.99USD at best bulk price >> ~400USD. — this excludes the time it takes to perform the modifications and upgrades. You can accelerate the process with magicite, but that would be phenomenally expensive. — so even if you try to ‘buy in’, your weapons will be weak for some time, #kupo! — when playing, attempt to collect a range of weaponry that will allow you to overcome tricky situations, kupo!
