#18 Noble False Widow Spider
Noble False Widow Spiders are one of the most venomous spiders in the United Kingdom. These are commonly mistaken for black widows spiders, mostly due to the skull pattern on their bodies.
Although not lethal, false widows still pose a threat. They’re equipped with venom that can cause intense pain for a maximum of 12 hours, once bitten.
However, some bites worsen with bacterial infections and can require more treatment, such as when soccer player James Gray had to cut out a piece of his flesh because of it.
