Katipō

The Katipō is a tiny spider of the Theridiidae family and is related to spiders such as the Black Window and Australian Redback.
They're endemic to New Zealand, and are the most venomous spider we have here.

But don't worry too much about encountering one, the Katipō is unfortunately an endangered species and are now rarer than Kiwi.
There's just a few thousand of these spiders left, in about 50 areas of the North Island and just 8 in the South Island.
It's also very much illegal to deliberately capture, kill or harm one.

Like most spiders, females are larger than males and both have similar markings.
The males of the species are so small that they are unable to bite humans, females on the other hand can bite, however they would much rather run away than try to fight. They'll try to do pretty much anything else but bite you, if a Katipō feels threated they will role up into a ball then drop to the ground, then will proceed to run for cover.
If one does get a venomous bite (keep in mind most bites will be a dry bite, meaning no venom will be released), it could cause a condition known as latrodectism. This will cause pain, muscle rigidity, vomiting, and sweating, however nobody has died from a Katipō bite in the last 100 years

Something interesting about the Katipō is the incredible variety of their markings.
The size and shape of the markings are different for each individual, some are brighter than others, some have white around the edges of the red and some have multiple patterns over their body.
For this skin I have gone with a more generic look.
I'll put in a good range of images to show you guys their diversity.
