On March 12, Imani, an 18-year-old gorilla at the San Diego Zoo, gave birth to a 4.6 pound baby via caesarian section. The infant was treated for pneumonia and other complications after birth at the animal hospital.
But 12 days later, baby and mama were reunited! Imani immediate cradled her baby in her arms and has been doting on the newborn ever since.

A fossil of a small tyrannosaur that lived 70 million years ago was recently discovered in northern Alaska. The pygmy dinosaur, called Nanuqsaurus hoglundi (which means “polar bear lizard”), is believed to be a close relative of Tyrannosaurus Rex.
N. hoglundi was much smaller than the T. Rex. Its skull measures 25 inches as compared to the T. Rex‘s 60-inch skull. Researchers have postulated that the pygmy tyrannosaur’s smaller stature was an adaptation to the cooler Arctic climate. Although the Arctic would have been much warmer in the Cretaceous Period than it is today, bouts of cold temperatures would have caused variations in the food supply.
Below is an illustration of the relative size of N. hoglundi (A) as compared to its larger cousin T. Rex (B and C). Although N. hoglundi was only about half the size of the T. Rex, it still was an impressive 23 feet from head to tail.

Since November 30, SeaWorld Orlando has experienced a penguin chick boom. Fifteen penguin chicks have hatched at their new exhibit, Antarctica, Empire of the Penguin, which features four different species of penguin: king, Adelie, Gentoo, and rockhopper.
From SeaWorld Orlando:
Although currently ranging in size from 6 inches to 21 inches, the king chick, the largest penguin at SeaWorld’s Antarctica will grow to be as tall as 2.5 ft. and its smallest, the rock hopper will grow to be approximately 12 inches tall.
Researchers in Western Australia are trying a new way to warn swimmers about sharks. Three hundred and thirty-eight sharks have been tagged with acoustic transmitters which will send a signal to a computer if a shark gets too close to land. The computer when then send out a tweet to warn swimmers that there is a shark in the area.
One concern is that the new system will provide a false sense of security because there are still many sharks without tags.
