Description:
'What I like best about this fascinating book is the detail. Brian Butterworth doesn't just tell us stories of animals with numerical abilities: he tells us about the underlying science. Elegantly written and a joy to read' - Professor Ian Stewart, author of What's the Use? and Taming the Infinite
'Full of thought-provoking studies and animal observations' - Booklist
'Enlightening and entertaining' - Publishers Weekly
The Hidden Genius of Animals: Every pet owner thinks their own dog, cat, fish or hamster is a genius. What makes CAN FISH COUNT? so exciting is the way it unveils just how widespread intelligence is in nature.
Pioneering psychologist Brian Butterworth describes the extraordinary numerical feats of all manner of species ranging from primates and mammals to birds, reptiles, fish and insects. Whether it's lions deciding to fight or flee, frogs competing for mates, bees navigating their way to food sources, fish assessing which shoal to join, or jackdaws counting friends when joining a mob - every species shares an ability to count.
Homo Sapiens may think maths is our exclusive domain, but this book shows that every creature shares a deep-seated Darwinian ability to understand the intrinsic language of our universe: mathematics
CAN FISH COUNT? is that special sort of science book - a global authority in his field writing an anecdotally-rich and revelatory narrative which changes the way you perceive something we take for granted.

Rejuvenates your Robovac, but one caution
I was a little wary buying third-party aftermarket parts for my Eufy Robovac 30c, however, all the parts in this kit are virtually identical to OEM parts. I replaced all three brushes and all three filters and let it loose on my Golden Retriever-inhabited living room. I can honestly say the result was a 50% increase in the amount of fur collected. I suspect that over time there is a loss of performance so gradual that it's easy to not notice. I assume the new filters returned the vacuum power to it's original level of suction was a big factor.
When I was browsing through all the available choices here on Amazon, a plastic "ring" kept appearing in many of the product images, however, people did not know what it is for or simply did not get one in their shipment. If you look at the photos I've attached one can see that I did indeed get one and figured out its purpose, to remove fur and/or hair from the horizontal brush.
The bottom line is that I would definitely buy this item again.
===========
EDIT, four weeks later: Since replacing the main roller brush with the one included with this product, I have experienced several βRoller brush is stuckβ shutdowns and alerts. In each case, there has been nothing tangled in the brush and the brush was free to spin. I have to say itβs quite annoying to come home expecting the floor to be cleaned but only to find this error long before the job was finished. Today it gave this error twice in one cleaning cycle. I never experienced this problem with the OEM roller brush.

Euphy works good as new!
Style: 19 Pack
As soon as I opened the package everything looked the same- pre-filters, filters, main brush, and side brushes. I changed the big brush first;the only issue was the new brush body didn't have the white arrows to help aligning but that didn't affect how the brush worked. I changed filter and pre-filter, and finally the side brushes.
When I turned on my "Goophy" and tried to let her run the side brushes were a little too (Goophy's side brushes sounded a little louder). I trimmed the side brushes a little and all was well. Goophy didn't want to run herself but it didn't take long for me to figure out it wasn't the new brushes ;just the operator pushing the wrong button. My Goophy Euphy did what she was supposed to do- vacuum the carpet and tile floor. Goophy Euphy still wanted to take the long way to her charging station which was nothing new and easily corrected.
Over all the new brushes and filter restored Goophy Euphy back to when we first used her!
