Yellow amycine jumping spider, Reserva Canadé, Ecuador

This yellow jumping spider has a translucent exoskeleton, showing the shape and movement of its eyes as it scans its surroundings. Thick eye chambers allow sufficient light to be collected despite its opacity.

A green bellied huntsman spider manages to subdue a  Jumping Jack ant but not before getting stung. The spiders outlook was unfortunately grim.  

Jumping Jack ants, native to Australia, possess a powerful sting similar to fire ants that allows them to paralyse prey, and causes swellings, fever, blister formation and increased heart rate for larger animals (and humans).

"The happy-face spider - Theridion grallator - exhibits an array of colour patterns on the back of its abdomen, sometimes resembles a smiling face. These spiders blend in with the undersides of leaves where they build their flimsy webs and catch prey."

This group of Stegodypus sarasinorum is shown taking down a much larger insect trapped in a web. Out of about 41,000 identified species of spiders, perhaps only about 25 species show characteristics where groups of spiders come together to co-operate in tasks. This social behaviour helps in catching larger prey, and ensures a more robust colony, which often live many years, longer than individual spider themselves.

Apologies for the crappy compression, as per the rules of tumblr, gifs need to be a certain file size. 

An un-instagrammed (except for corrected colour balance) can be found here: 

The above image taken with a Nexus 5, F/2.4, exposure: 1/30, 400ISO.

The picture taken with the iphone was processed with instagram so its  metadata means bugger all.

This pink Thomisus onustus or crab spider waits on a flower, using its bright camouflage to help hide if from birds. The spider doesn't make any web, but instead actively pursue their prey. Emerging spiderlings may consume pollen or nectar when insects are sparse.

Brazilian Wandering Spider (Phoneutria spp)

When the brazilian wandering spider feels threatened, it assumes a distinctive stance to intimidate any potential threat. By raising their front two legs, they make the spider seem larger in size, accentuate the spiders large red jaws, and display a striped patterned that's not normally visible.

The net casting spider (family Deinopidae) has exceptional eyesight which helps them to cast a small web between their forward legs and capture any prey unfortunate enough to wander below them. Their front eyes are so prominent compared to their other six eyes that they look like they only possess two eyes.

The Australian funnel web spider uses a collection of cytotoxins to break down tissue, and neurotoxins which inhibit nervous system functions to immobilize and help consume its prey. Unfortunately, the venom also has some potency on humans, particularly atraxotoxin, which causes overproduction of neurotransmitters, causing muscle paralysis. 

However, since the inception of very effective, purified Rabbit IgG antivenom, combined with modern first aid practises, there have been no deaths since the introduction of the antivenom in 1981.
