Portia fimbriata, known as the Fringed Jumping Spider or often just as Portia is renowned as the world's most intelligent spider. It is a spider hunter which modifies its hunting strategies and learns from situations as it encounters them.
The Fringed Jumping Spider (Portia fimbriata) is renowned as the most intelligent spider on Earth. It has the ability to problem solve and modify its methods when stalking prey. Its prey is other spiders and they usually don't see this stealthy assassin coming.
Although spiders can't literally count one-two-three, the research suggests some jumping spiders have a sense of numbers roughly equivalent to that of 1-year-old humans.
The researchers found that the smaller the spider, the bigger its brain relative to its body size. In some spiders, the central nervous system took up nearly 80 percent of the space in their bodies, sometimes even spilling into their legs.
The best beginner spider would be a tarantula such as the Chilean rose, Mexican Redleg, or Costa Rican Zebra. These species aren't terribly venomous and are pretty docile when compared with some other tarantulas (their venom is comparable to bee venom).
The Maratus personatus, or the masked peacock spider, was recently captured on camera doing an intricate mating dance. The arachnid, with its deep blue eyes, is only a few millimeters in length, and its semaphore style dance and overall soft furry appearance has led to it being dubbed the cutest spider in the world.
Now scientists have found that spiders can hear you from across a room. The discovery came as a surprise because, technically, spiders do not have ears. However, the latest research shows that the hairs on spiders' legs are so sensitive that they can detect human speech from several metres away.
They don't feel 'pain,' but may feel irritation and probably can sense if they are damaged.
While some spiders catch prey with webs, others -- such as jumping spiders -- hunt using sharp eyesight. Because they don't have eardrums, scientists have always assumed that arachnids were deaf to airborne vibrations. But biologists at Cornell University have now shown that spiders can detect sounds after all.
Spiders do have feelings, but unlike a dog or a cat, they won't bond with you. In fact, they likely won't even recognize you. They simply aren't hardwired to be companions to humans and should never be bought at pet stores, online, or anywhere else.
While the theory is unproven, it is likely that spiders can detect human fear. However, there are only few studies about this topic and it is not yet known for certain. Different animals have sensory organs that are able to identify different stimuli.
Spiders don't have ears like we do, and many have poor eyesight. But they can sense vibrations, like those that happen when an unlucky insect touches their webs. And instead of eardrums, spiders hear using tiny, sensitive hairs that move in response to sounds.
According to the Scientist Supreme, Peter has an IQ of over 250.
Unlike most other invertebrates, spiders - like humans - have more centralised organs such as the heart and the brain.
They found that not only did the spiders remember they caught something, but they also remembered features of the prey and the quantity of it. Memory in tiny creatures was long thought to be a hardwired behavior that didn't require much mental capacity.
The researchers mated 68 virgin P. globosus females with two males. They found that the number of squeezes the males made were associated with the number of times the females cried out during sex. Stridulations became more frequent if males failed to loosen a squeeze in response to a previous plea.
To a spider, losing a leg isn't a very big deal. Heck, some even voluntarily castrate themselves. Overall, there's a slight lag in development time. Being short a leg or two (or six) is going to slow you down a bit, which makes prey harder to catch.
Leg loss is a common phenomenon in spiders, and according to the species 5% to 40% of the adults can present at least one missing leg. There is no possibility of regeneration after adult moult and the animal must manage with its missing appendages until its death.
“Our studies extended the range of auditory sensitivity to more than 3 metres – over 350 body lengths – for our spiders.” The team established that the spiders freeze when exposed to low-frequency sounds of about 80 to 400 hertz that resemble a low hum, or buzz.
So, if you sing loudly to a spider, play the mandolin for it, or take it to a rock concert, the sound waves produced can elicit responses in spiders.
Snails, spiders and octopi have something in common- they all have blue blood! We're not talking in the sense of royalty, these creatures literally have blue blood. So why is their blood blue and ours red? One of the purposes of blood is to carry oxygen around the body.
The color that spiders tend to hate is light blue. People don't just paint their porches light blue for the aesthetic. Painting your porch ceiling in this shade is a pretty effective way of keeping spiders away. The color is also known to repel wasps.
Why hello there, this masked peacock spider above (Maratus personatus), looking a little like The Spirit, was voted the cutest spider. Jumping spiders are also the most diverse family of spiders, with over 5,800 species in the group.
Over five hundred Critically Endangered Desertas wolf spiderlings have been born to two female spiders inside our very own Bug World – boosting the world's once dwindling population. The new babies who are just 4mm in diameter are expected to grow to around 12cm by the time they're adults.
