Some birds are afraid of butterflies
|
view preview
It turns out that butterflies with eyelike spots evolved to scare off predators. A recent study concluded that about 68% of the birds that were shown an image with eye-mimicking spots, flew away or showed signs of being startled such as chirping a warning call as they flew in for food (within a controlled setting). That’s on par with the 57% showing the same reactions to the owl with open eyes, the research team notes. The full study can be analyzed in the link below: Source: http://rspb.royalsocietypublishing.org/content/282/1806/20150202 ...

These wannabe spiders use thorn-like weapons on their arms to attack small prey
|
view preview
Belonging to the class Arachnida, Amblypygids, also known as whip spiders or tailless whip scorpions, form a separate order of arachnids alongside the spiders, scorpions, and others. The name "amblypygid" means "blunt rump", a reference to a lack of the flagellum ("tail"). They are harmless to humans, and possess no silk glands or venomous fangs. They rarely bite if threatened, but can grab fingers with pedipalps (thorn-like appendages), resulting in thorn-like puncture injury. ...

Ever seen a black flamingo?
|
view preview
On the Mediterranean island of Cyprus, you might be lucky to find a black flamingo. Normal flamingoes are born white and grey, and turn their iconic shade of pinky orange around the age of two, as a result of the high carotenoid content of the algae and crustaceans that they eat. Experts believe that this individual (and potentially the other bird spotted in Israel) has a genetic condition that causes it to overproduce melanin, changing its feathers to black.

The rainbow eucalyptus tree has its name because of its vibrant colored bark
|
view preview
Eucalyptus deglupta, commonly called rainbow eucalyptus, is a very large, fast-growing, broadleaved evergreen tree that is native to moist humid tropical forested areas with high rainfall in New Guinea, Indonesia and the Philippine Islands (Island of Mindanao). It is perhaps best noted for its smooth orange-tinted trunk bark which peels in summer to reveal a unique and sometimes stunning multi-colored bark (as described by the common name of rainbow eucalyptus) consisting of streaks of pale green, red, orange, gray and purple-brown. ...

If you thought being left-handed was odd, read this
|
view preview
A rare condition, known as situs inversus, is when a person has their major organs mirrored from their normal positions. So, for example, the heart would be on the right side of the body, or the liver and gall bladder are on the left side. It is a congenital condition (meaning it's tied to your genetics) that affects 1 in 20,000 people - including Spanish-born singer Enrique Iglesias. Situs inversus is generally an autosomal recessive genetic condition, although it can be X-linked or found in identical "mirror image" twins. ...
