A new study has found that certain bats use echolocation calls for orientation and foraging — as well as to send sex information to help them find and keep mates. Male greater sac-winged bats, which were the focus of the research, “court females whenever the opportunity arises,” said Mirjam Knörnschild, a researcher at the University of Ulm in Germany and the study's lead author. The calls can include encoded information on identity, age, sex, group affiliation and other more specific information about the bat. Knörnschild suspects that many "bat species are capable of encoding/extracting social information in and from echolocation calls.” — Read it at Discovery News
The Pegomastax africanus, a newly discovered species of heterodontosaur, was a 2-foot-long dwarf dinosaur with fangs and porcupine-like quills. It was "scampering around between the toes of other dinosaurs at the dawn of the dinosaur era," said study author Paul Sereno, a paleontologist with the University of Chicago who published his findings in the journal ZooKeys. According to Sereno, the plant-eating dinosaur species, who lived in southern Africa, would have been about the size of a cat. — Read it at National Geographic News
The Point Defiance Zoo in Washington announced on Wednesday that, after a vote by the public, its 6-week-old Sumatran tiger cub has been named Dumai — and he's also getting a new buddy. Berani, a 5-week-old Malayan male cub is due to arrive at the zoo next week from the Tulsa Zoo. The cubs, who will grow up together, have both been hand-reared. — Read it on Facebook
The director says that his childhood pet inspired his new stop-motion movie about a boy who uses science to bring his beloved dog back to life. "I had this strong connection with a mutt we had named Pepe," said Burton. "It was a good connection . . . It was very powerful. The dog was not meant to live very long because of a disease he had, but he ended up living quite a long time." The black-and-white film hits theaters on Friday. — Read it at Aceshowbiz, and watch a trailer for the movie
Robert Irwin, the 8-year-old son of the late “Crocodile Hunter” Steve Irwin, reached a milestone this week when he fed freshwater crocodiles for the first time at the Australia Zoo. "It was really, really fun," he told reporters. "Next, I'd like to feed a big alligator, and then a saltwater croc." Robert was just 2 years old when his dad died in 2006. — See the photo at People Pets
