10 Miracle Mice
Weird Fact: A mouse can fit through a hole the size of a ballpoint pen
During the summer months, mice will generally live outside and remain contended there. But as soon as the weather begins to cool, they seek the warmth of our homes. Because of their soft skulls and gnawing ability, a hole the size of a ballpoint pen (6mm – 1/4 inch) is large enough for them to enter en masse. Once inside, they will constantly gnaw at virtually anything – including concrete, lead, and plastic. This is to keep their ever-growing teeth at a convenient length. Contrary to popular belief, mice don’t generally like cheese – but will eat it on occasion. Mice can jump up to 46cm (18 inches), swim, and travel vertically or upside-down. To mouse proof your house, check all small openings with a ballpoint pen – if it fits the hole, it will let mice in.
9 Square Eyes
Weird Fact: Unlike most creatures, goats have rectangular pupils
We all imagine pupils to be round – as they are the type we see most often (on humans) – but goats (and most other animals with hooves) have horizontal slits which are nearly rectangular when dilated. This gives goats vision covering 320 – 340 degrees; this means they can see virtually all around them without having to move (humans have vision covering 160 – 210 degrees). Consequently, animals with rectangular eyes can see better at night due to having larger pupils that can be closed more tightly during the day to restrict light. Interestingly, octopuses also have rectangular pupils.
8 Blind Horses
Weird Fact: Horses can’t see directly in front of themselves
A horse has considerably wide vision (and the largest eyes of any land mammal) – being able to see a total field of up to 350 degrees. Horses have two blind spots – the first is directly in front of them and the other is directly behind their head. As far as seeing details, horses are red color blind and have vision of 20/33 (compared to a perfect human vision of 20/20)Continue Reading on listverse.com
