Australia Waters Harbor Hybrid Sharks
2012-01-03 08:09:49

Marine scientists from the University of Queensland have discovered hybridized sharks off Australia´s east coast, leading them to believe that some of these predatory beasts display a tendency to interbreed, challenging long-standing scientific theories regarding shark behavior. This is the first time scientists have confirmed a substantial number of hybrid sharks off Australia´s coast, speculating that it may be an adaptation or reaction to climate change; and scientists now...

New Zealand Beach Scene Of Orca-Shark Battle
2012-01-02 09:00:01

A spectacular display of nature´s sometimes cruel cycle of life was witnessed by beachgoers at Blue Cliffs Beach in Tuatapere, New Zealand when orcas, also known as killer whales, forced a group of large sharks to swim into shallow waters or risk being eaten. One shark desperate to escape from the enormous beasts even beached itself on the sand and was filmed desperately flapping around in a bid to escape the whales, which were unable to move onto the sand, reports Rick Dewbury for...

California Academy Scientists Added 140 New Species To List In 2011
2011-12-16 05:42:15

The California Academy of Sciences said on Wednesday that its researchers added 140 new species in 2011. The new species includes 72 arthropods, 31 sea slugs, 13 fishes, 11 plants, nine sponges, three corals, and one reptile. The scientists made their finds over six continents and three oceans, including Atlantic, Pacific, and Indian. Among the 140 species discovered, researchers found four new sharks, including one with a blade-like snout. The African dwarf sawshark was found at...

Biologists have long assumed that all jawed vertebrates possess a full complement of nearly identical genes for critical aspects of their development. But a paper in the December 16 issue of Science with Benjamin King of the Mount Desert Island Biological Laboratory (MDIBL) as lead author shows that elasmobranchs, a subclass of cartilaginous fishes, lack a cluster of genes, HoxC, formerly thought to be essential for proper development. Hox genes dictate the proper patterning of tissues...

The Physics Behind Great White Shark Attacks On Seals

Scientists use basic principles of underwater optics, physics to understand predator-prey interactions A new study examining the complex and dynamic interactions between white sharks and Cape fur seals in False Bay, South Africa, offers new insights on the physical conditions and biological factors underlying predator-prey interactions in the marine environment. University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science assistant professor Dr. Neil Hammerschlag, and a...

Evidence Found Of Ancient Deep Sea Fishing By Humans
2011-11-25 09:51:37

An Australian archaeologist has discovered ancient fish bones in a cave in East Timor -- a small island country northeast of Australia in the Lesser Sunda Islands -- that contain the ancient remains of more than 38,000 fish bones from nearly 2,900 individual fish, a sign that humans may have gone deep-sea fishing as many as 42,000 years ago. Among the fish bones were those of tuna and shark, clearly brought to the cave -- called Jerimalai -- by human hands. And to back that up, the...

Image 1 - Ancient Shark Attack Preserved In Fossil Whale Bone
2011-11-11 05:36:51

A fragment of whale rib found in a North Carolina strip mine is offering scientists a rare glimpse at the interactions between prehistoric sharks and whales some 3- to 4-million years ago during the Pliocene. Three tooth marks on the rib indicate the whale was once severely bitten by a strong-jawed animal. Judging by the 6 centimeter spacing between tooth marks, scientists believe the attacker was a mega toothed shark Carcharocles megalodon, or perhaps another species of large shark which...
