Mirror Self Recognition Test (MSR)
Like many animals, until a child is about 18 months, they don’t understand that the image in the mirror is a reflection.
Magpies are one of the few animals that seems to pass the MSR test. The bird in this vidoe has a yellow sticker placed under it’s beak on the chest. It can only see the sticker in the mirror.
A little more in depth of Dr, GG. Gallup Jr. article and self recognition in chimpanzees:Nature magazine
Researchers, led by Avigdor Cahaner bred the featherless chicken at the genetics faculty of the Rehovot Agronomy Institute, Tel Aviv, Israel.
- 50 years of breeding
- Not genetically modified
- Taste the same
- Same nutritional value
- Faster growth
- Their meat is lower in fat
- They are energy efficient and require less food to produce the same amount of meat
- They can adapt better in hot climates
- The breed is more ecofriendly, as there is no need for plucking, a process that contaminates large quantities of water with feathers and fat tissues.
- Hard time surviving in cool and cold areas
- More prone to parasites, mosquitoes and sunburns
- Males sometimes fail to mate,
- as the feathers are required in certain mating rituals (flapping wings, showing them off etc.)
- Females are routinely injured during mating
- by the rooster’s nails and beak, as they have no feathers to protect their skin. For this reason, breeders commonly remove the male’s nails.
A number of other hairless, featherless animals:
- Hairless guinea pigs called skinny pigs
- Crossbreed of hairless lab animal and regular guinea pig created hairless mutation
- Hairless Hamster
- Genetic mutation
- Hairless Cats

- Featherless birds
- Can pluck out feathers due to stress

GIANT SPIDER!!!!!!! AAAHHHHHHHHHHHHHHHHHHHHHHHHH! I gotta go lay down.
AKA giant bird-eating spider,
giant bird-eating tarantula,

- What it’s got going for it:

- scare off an attacker by rubbing together bristles on its first and second pair of legs, producing a hissing sound
- barbed, irritating hairs on its abdomen,
- can flick at an attacker,
- potentially causing severe irritation to the skin, eyes, nose and mouth
- can flick at an attacker,
- may also rear up on its hind legs, showing its large fangs
- the female has been known to add irritating hairs from its abdomen to the egg sac.
- Wicked strong fangs can puncture a mouse skull
- secretes venom into punctures to liquefy, then it eats.
- Will attack whatever they encounter pretty much.
