They're horrible, the poor snail. Having glowing antennae looks pretty painful. Can't help but wonder what would happen if I were to ingest some somehow.
Completely off topic but my mum did this like 15 years ago.

Does anyone know the name of the microscopic prawn thing that wields a kind of supersonic hammer against its prey?
what kind of tea have you been drinking?
Not sure, google throws up mantis shrimp, but they're defintiely not microscopic.
In smashers, these two weapons are employed with blinding quickness, with an acceleration of 10,400 g (102,000 m/s2 or 335,000 ft/s2) and speeds of 23 m/s from a standing start,[7] about the acceleration of a .22 calibre bullet.[8][9] Because they strike so rapidly, they generate cavitation bubbles between the appendage and the striking surface.[7] The collapse of these cavitation bubbles produces measurable forces on their prey in addition to the instantaneous forces of 1,500 newtons that are caused by the impact of the appendage against the striking surface, which means that the prey is hit twice by a single strike; first by the claw and then by the collapsing cavitation bubbles that immediately follow.[10] Even if the initial strike misses the prey, the resulting shock wave can be enough to kill or stun the prey.
The snap can also produce sonoluminescence from the collapsing bubble. This will produce a very small amount of light and high temperatures in the range of several thousand kelvins within the collapsing bubble, although both the light and high temperatures are too weak and short-lived to be detected without advanced scientific equipment. The light emission and temperature increase probably have no biological significance but are rather side-effects of the rapid snapping motion. Pistol shrimp produce this effect in a very similar manner.
Frogs are lazy bastards, which is why they have such huge goddamned eyes, eyes that are placed so that frogs can see almost 360 degrees without moving at all. Postulated theories for their demonstrated behavior of being a bump on a log include the idea that frogs have licked themselves one too many times and are simply too stoned out to even care about anything beyond their parents' basement. The true weirdness of a frog's eyes doesn't lie in its 360 degree vision, nor does it lie in the fact that frogs close their eyes when swallowing because they use the back of their eyeballs to force the food down their throat (but that is pretty awesome). No, the cool thing is that frogs' eyes are so sensitive that they can detect the presence of a single photon.
Here's some rudimentary physics: a photon is a packet of light. Quantum theory started when scientists observed that sometimes a photon acts like a particle (like a solid packet) but it also sometimes acts like a wave (like the rest of the electromagnetic spectrum). Nobody could figure this out for a while until somebody said, Hey, maybe light is acting this way because ghost photons from parallel universes are crossing over and fucking up its shit.
If they ever get around to proving this theory, then that means frogs observe events happening on the quantum level. Always. Continuously. And not just able to see events in our universe, but also across an infinite amount of universes, including that one where Furrydom has risen as the dominant religion and you go to church every Sunday dressed as a giant teddy bear. This is why the world loves Hypnotoad.
Because he sees everything
a lot like my parrot, his snap was sudden and painful.In smashers, these two weapons are employed with blinding quickness, with an acceleration of 10,400 g (102,000 m/s2 or 335,000 ft/s2) and speeds of 23 m/s from a standing start,[7] about the acceleration of a .22 calibre bullet.[8][9] Because they strike so rapidly, they generate cavitation bubbles between the appendage and the striking surface.[7] The collapse of these cavitation bubbles produces measurable forces on their prey in addition to the instantaneous forces of 1,500 newtons that are caused by the impact of the appendage against the striking surface, which means that the prey is hit twice by a single strike; first by the claw and then by the collapsing cavitation bubbles that immediately follow.[10] Even if the initial strike misses the prey, the resulting shock wave can be enough to kill or stun the prey.
Mind you, is that badass? Setting up shop in place of a body part you just ate? Pretty rough.
Rope trick is the term given by physicist John Malik to the curious lines and spikes which emanate from the fireball of certain nuclear explosions just after detonation.
