SPIDERS EAT FISH?

Spiders are normally thought to eat insects.But a study by scientists is suggesting that those near water are eating fish.And some use powerful poisons to kill fish bigger than them as article shows- A study by scientists has found that Fish suffer pain,good memories,co-operate  and learn from another.Dr.Culum Brown, Maquarie University,Australia.Those eyes.

SPIDERS that can catch and devour fish are crawling over each and every continent in the world. Except for Antarctica, a continent where we all need to move to.
A new report in journal PLOS ONE has found that these spiders are practically everywhere, with some that can even take down fish that are five times their own weight.
Marie Herbertstein from Macquarie University told National Geographic that “fish predation by spiders has always been a bit of an oddity”. However she says this new study makes a “compelling argument” that this type of behaviour in spiders is widespread.
The spiders only live in freshwater areas like ponds and hunt for their little fish friends on foot, rather than using a web. Like Jesus, some can even walk on the water’s surface.
To get their prey, the spiders “anchor their hind legs to a stone or a plant, with their front legs resting on the surface of the water,” the journal says. Once they’re in predator mode, even the slightest ripple in the water can cause them to attack.
The spider’s mouth will then penetrate the fish’s flesh, where it injects some lethal poison that goes straight for the nervous system and kills the fish. Once the fish is dead, the spider then sprays a chemical (or alien acid) on the body that liquefies it and makes it easier to eat.
We aren’t sure about you, but none of us are sleeping tonight
