Bats Rely On Vision To Navigate, Echolocation To Catch Insects: Study
2013-12-13 07:34:50

April Flowers for redOrbit.com - Your Universe Online\ Bats rule the night skies, using the power of echolocation, or reflected sound. More than 1,000 species of echolocating bats exist, compared to just 80 species of nocturnal non-echolocating birds. It seems that normal vision works in tandem with echolocation to give bats an evolutionary edge, however, no one knows exactly how. A new study, led by Arjan Boonman and Yossi Yovel of Tel Aviv University's Department of Zoology, suggests...

Nectar Bat Uses Stealthy Moves To Catch Its Evening Dinner
2013-12-12 15:39:25

Lee Rannals for redOrbit.com - Your Universe Online New research shows the Pallas long-tongued bat is a very stealthy predator when it comes to catching insects. Previously, scientists believed the nectar-feeding bat ate insects in passing, but the latest research shows it targets its moving prey with stealthy precision. The team proved for the first time that the Pallas long-tongued bat uses a stealthier form of echolocation. Echolocation is a physical trait that involves the...

Killer Whales Use Stealth Approach When Hunting Prey
2013-12-04 04:57:23

[ Watch the Video: Stealthy Tactics Used By Orca To Catch Their Prey ] redOrbit Staff & Wire Reports - Your Universe Online Newly discovered evidence that killer whales can hunt marine mammals during the nighttime has led scientists to suggest that the creatures can use their hearing to help locate prey, according to research presented at the 166th Meeting of the Acoustical Society of America (ASA). For example, the study authors said that the whales eavesdrop on male harbor...

Dolphin Study Provides Insight Into History, Conservation Of Species
2013-10-30 10:15:45

April Flowers for redOrbit.com - Your Universe Online A research team from Nanjing Normal University and BGI has completed original genomic research on the Yangtze River dolphin (Lipotes vexillifer), commonly known as Baiji. The study, published in Nature Communications, provides new insight into the genetic and evolutionary adaptations of dolphins and valuable resources for the conservation of mammals, and in particular, of cetaceans. The baiji has been nicknamed "goddess of the...

Bats And Whales Share Echolocation Success Story
2013-10-30 04:37:49

[ Watch the Video: Echolocation Frequencies Similar In Bats And Whales ] April Flowers for redOrbit.com - Your Universe Online What could a 50 ton whale and a one gram bat have in common? They share a success story - both have developed the ability to use echolocation, a type of biological sonar, for hunting. A new study from Aarhus University and the University of Southern Denmark reveals that the biosonar of toothed whales and bats share surprisingly many similarities - even though...

New Electric Fish
2013-09-25 12:54:23

Lee Rannals for redOrbit.com - Your Universe Online A new species of electric fish has been discovered in the murky waters of the upper Mazaruni River in South America. Scientists reported in the journal Zoological Scripta that they discovered a species that they've dubbed Akawaio penak in the remote regions in northern Guyana during an expedition. The team analyzed tissue samples collected during the trip, and found that the fish represents not only a new species but also a new genus....

Bats And Dolphins Have Genetic Similarities
2013-09-05 04:58:11

[ Watch the Video: Genetic Similarities In Echolocation Discovered In Bats And Dolphins ] redOrbit Staff & Wire Reports - Your Universe Online Convergent evolution – the evolution of similar traits in drastically different types of creatures – is widespread not just at the physical level but also at the genetic level, according to new research published in this week’s edition of the journal Nature. As part of their study, scientists from Queen Mary University of London...

Echolocation - With Practice, Anyone Can Learn It
2013-08-30 04:23:17

redOrbit Staff & Wire Reports - Your Universe Online Humans can learn to use echolocation to navigate and to find objects, according to new research appearing in the latest edition of the biology journal Proceedings of the Royal Society B. Professor Lutz Wiegrebe of the Ludwig-Maximilians-Universitaet (LMU) Department of Neurobiology and colleagues have now shown how people can acquire the capacity for echolocation, though they emphasize doing so takes a considerable amount of time...

The larger the moth, the better hearing senses it needs if it wants to avoid its worst enemy, the bat. A large moth is easier to detect for a bat, and therefore evolution has forced large moths to develop larger and more sensitive ears. But the improved hearing comes at a price, says sound researcher Annemarie Surlykke from University of Southern Denmark. Bats orient themselves through echolocation, and they find their prey by emitting calls and then process the echoes reflected back to...

Dolphins Call Each Other Names
2013-07-23 13:08:58

Brett Smith for redOrbit.com - Your Universe Online Dolphins have previously shown the ability to perform simple math, rescue people and even spot mines for the military. A new study from British researchers shows that the marine mammals are capable of doing something else once thought to be unique to humans - call each other by name. According to the new study published in the Proceedings of the National Academy of Sciences, individual dolphins have a signature whistle that...

Brandt’s Bat, Myitus brandtii
2013-10-11 08:07:41

The Brandt’s bat has a large population in northwest of England but is endangered in Austria. The Brandt’s Bat has shaggy brown fur with a pale grey belly. This bat is not a large bat and weighs less than half an ounce and measures up to two inches long. Its wingspan is more than triple its body length at 7.5 to 9.5 inches. Brandt’s bat eats only insects (insectivorous) and is not blind. However, echolocation is used for “night-vision,” so that while hunting at night it does...

Common Noctule, Nyctalus noctula
2013-09-17 13:48:36

The common noctule bat is commonly found in Europe, Asia, and North Africa. This bat has a body length of three inches with a wingspan of approximately 14 inches. It is the largest bat found in Europe. It commonly lives in forests but due to human growth there have been populations found in towns dwelling in buildings such as church steeples. The common noctule starts to hunt and fly at dusk which is earlier than other members of the species. These bats fly at speeds up to 31 miles per...

New Zealand lesser short-tailed bat, Mystacina tuberculata
2013-09-17 13:41:27

The lesser short-tailed bat is only found in New Zealand and is the only living species of bat in the Mystacinidae Family. The short-tail is commonly located on the North Island of New Zealand using the forests as its habitat. Roosting is done primarily alone but there have been known colonies of over 100 bats. It prefers to use already hollowed trees or crevices but will chew out a burrow in the wood using its sharp incisor teeth. These roosting locations are only used for a few weeks...
