Pedipalps are these little frontal limbs that the spider uses for a range of things like sensing. While male jumping spiders are smaller than their female counterparts, males have larger pedipalps.
Proportionally, the back bodies (the abdomen) of male jumping spiders are smaller relative to the front body (the thorax). Anatomically, this is opposite amongst females as they have relatively larger abdomens.
Another hugely misunderstood animal. Jumping spiders are ferociously adorable if you ask me, though to other people they’re serial killer vermin worthy of a boot to the thorax.
There are thousands of species of jumping spiders all over the world and they manifest in so many different colours and shapes. But obviously unique to them is their ability to jump – several times their own length. Besides that, their behaviour and movements are also very different from other spiders. I usually describe them as “charismatic” with their big eyes and erratic, curious movements.
Anyways, I wanted to highlight this little one from Zambia. Male spiders can be identified by their large front paddle-like “arms” called pedipalps, and many of them have relatively small back bodies relatively to female spiders.
