    Ancient super-predator eyes found in Australia

  • A University of Adelaide illustration shows an artist's impression of an Anomalocaris ...
Australian scientists on Thursday hailed the discovery of a pair of insect-like eyes belonging to a freakish prehistoric super-predator which trawled the seas more than 500 million years ago.
Measuring three centimetres (1.2 inches) across and with a whopping 16,000 individual lenses the fossilised eyes, from a huge shellfish-type creature called anomalocaris, were found in rocks on Australia's Kangaroo Island.
Anomalocaris could grow up to one metre long and were considered the "great white shark" of the Cambrian era, topping the ancient marine food chain, according to lead researcher John Paterson.
Modern-day houseflies have about 3,000 lenses in their eyes, while dragonflies have about 30,000 -- the only creature known to have more lenses than anomalocaris.
Paterson said the discovery showed that anomalocaris had lived in well-lit, clear waters and had developed sophisticated vision extremely rapidly, likely triggering an evolutionary "arms race" among other creatures.
Spines, poison glands and other defence mechanisms had probably erupted among creatures eager to escape detection by its huge eyes, which protruded from the side of its head on stalks.
"When you look at the animal itself it's quite an alien-looking beast," Paterson, from Australia's University of New England, told AFP.
Aside from its protuberant eyes, anomalocaris had formidable claws lined with spines which it used to catch its prey and a "gnarly-looking circular mouth with teeth-like serrations inside".
"Those serrations were either used for shredding or chomping up its prey, so it was a pretty nasty-looking creature," Paterson said.
The fact that anomalocaris had been found to have compound eyes also confirmed it was an ancestor of modern arthopods, which include insects and shellfish, said Paterson, whose study was published in Nature.
When the specimen was originally trapped in seafloor mud about 500 million years ago Australia, then part of the Gondwana supercontinent, was in tropical waters straddling the equator, Paterson said.
The fossil had been pushed from the sea floor at about the same speed human fingernails grow and eventually ended up on Kangaroo Island -- now a hotbed of Cambrian artefacts -- off Adelaide in South Australia.
Paterson said the site was riddled with "a variety of fairly enigmatic" specimens that remained a mystery to science and were difficult to classify because they were from a very early period in animal evolution.
"The body plans of animals that we're familiar with today were still kind of being tinkered with in the Cambrian," he said.
"Sometimes they have features that are completely foreign to what you would see in a modern organism."
Though anomalocaris specimens had been found before in Canada and China, Kangaroo Island was the first place an intact eye had been discovered, due to the unique shale rock it was trapped in, which had once been "zero oxygen" mud.
"Within the mud or within the sediment there's essentially no oxygen to allow for microbes to start to break down soft tissues," Paterson said.
"What we've seen in the Emu Bay shale at Kangaroo Island is a much better picture of what was living there at the time than you would otherwise get in a conventional fossil deposit."

Why shouldn't things be largely absurd, futile, and transitory? They are so, and we are so, and they and we go very well together.

Zakk, ovo su, ako se dobro sećam - evropske pčele, manje agresivne.
Japanske pčele su razvile zaštitni mehanizam: kada se pojavi stršljen-izviđač, blokiraju mu izlaz napolje, a onda mahnito mašu krilcima oko njega, da bi povećale temperaturu i - živog ga skuvaju (stršljeni su izuzetno osetljivi na povećanje temperature). Tako ga spreče da obavesti ostale "stršljene - kriminalce". Vrlo dovitljive pčelice :)

Nema to veze sa rešenjem koje su pronašle japanske pčele, nego pre sa veličinom.

Još ako je i izrazito otrovno (a jeste), eto ideje za efikasno biološko oružje, koje može da prekrije cele gradove živom.

Hemiju obožavam. Nikada nisam imala jači utisak uvrnutosti života nego kada sam izučavala hemiju - elemente, jedinjenja i reakcije. Atome, molekule i formule. Toliko se svaki (funkcionalni) delić tu uklapa u celinu, koja je opet, na globalnom planu, funkcionalna, da to ostavlja bez daha.

U to ime sam sa drugaricom u osnovnoj crtala veliki periodni sistem elemenata. Toliko smo se trudile oko njega (imale smo pomoć drugaricinog ćaleta - grafičara), da nastavnica nije htela da stavi poster, kada ga je dobila, već je naš nacrtani sistem ostao na počasnom mestu iznad table...

Fantastična hemija.

Glaucus Atlanticus Sea Slugs:
G. atlanticus is able to feed on P. physalis due to its immunity to the venomous nematocysts. The slug consumes the entire organism and appears to select and store the most venomous nematocysts for its own use. The venom is collected in specialized sacs (cnidosacs), on the tip of their cerata, the thin feather-like "fingers" on its body. Because Glaucus stores the venom, it can produce a more powerful and deadly sting than the Man o' War upon which it feeds.
