The term knot came from how sailors calculated speed. They threw a log with a rope attached to it overboard. The rope had knots evenly spaced (every 47 feet and 3 inches). Therefore, by calculating the knots let out in a specific time frame (every 28 seconds) the speed was calculated.
Even though they have ten legs – not, eight – we’ve always said horseshoe crabs are members of the arachnid family. It was first theorized by E. Ray Lankester in 1881. But, until recently, it had not been proven in terms of genetics. Scientists at the University of Wisconsin-Madison studied the molecular evolutionary patterns of […]

Epipelagic is the area of the water column extending from the surface of the water down to 700 feet. Since is the only zone that the sunlight can penetrate this is the only zone where plants reside.

According to this article from The Royal Society (published November 2010) whales are very prone to the harmful rays of the sun. The scientists discovered whales that spend more time at the surface of the sea had more skin cells exposed and therefore were showing more damage from the ultraviolet radiation. It was even pointed […]
