Scientists at Work: Uncovering the Mystery of When and Where Sharks Give Birth
If you have a toddler, or if you encountered one in the last year, you’ve almost certainly experienced the “Baby Shark” song. Somehow, every kid seems to know this song, but scientists actually know very little about where and when sharks give birth. The origins of these famous baby sharks are still largely a mystery. Many of the large iconic shark species – like great whites, hammerheads, blue sharks and tiger sharks – cross hundreds or thousands of miles of ocean every year. Because they’re so wide-ranging, much of sharks’ lives, including their reproductive habits, remains a secret. Scientists have struggled to figure out precisely where and how often sharks mate, the length of their gestation, and many aspects of the birthing process. >click to read< 13:51
Sharks and seals: A success story ?
With five shark attacks on people since 2012 — including swimmers, kayakers, a paddleboarder and a fatal attack on a bodyboarder last year — surfers, swimmers, public safety officials and business owners now worry that the ocean is suddenly not safe. Some see an imbalance that requires corrective measures, like a cull of seals and maybe sharks to reduce risk and bolster fish harvests. But others marvel at a pair of conservation success stories in an era where species extinction is more often the news. >click to read<23:54
Great whites plentiful off US west coast
Great white sharks are likely rising in numbers off the coast of California and are not at risk of extinction despite some reports to the contrary, US researchers say.By accounting for all life stages of sharks there, researchers found that their numbers were more likely around 2000, not 200.

PHOTOS & VIDEO: In search of great whites off Chatham, Ma
Julia, a great white shark, has arrived on Cape in May for the last few years and usually spends until October around Chatham Inlet and Monomoy. But this year she eschewed Chatham in favor of Orleans. “For some reason we don’t know,” said Greg Skomal, a shark researcher with the Massachusetts Division of Marine Fisheries. “Predictability is what you want when you try and manage beaches.” Manage BEACHES? more@wickedlocal 09:31
Great White Sharks Are Back – Has a marine mammal conservation program become too successful?
Gordon Waring, a seal specialist at the NOAA, cautions that marine biologists don’t actually know how seals interact with fisheries, and so far there is no sign that they are eating more than their habitat can support. (seal specialist??,,don’t actually know??) wow. continued@ slate
Shark trackers plot migration of great whites up and down East Coast
The three East Coast sharks tracked by Ocearch are the first white sharks in history with Facebook followers. As of Saturday, both Lydia and Mary Lee, a 3,500-pounder named after Fischer’s mother, were in waters off the southeast coast of the United States. In early May, Lydia visited Georges Bank fishing grounds off Massachusetts. During one 12-minute period on May 6 she swam a distance comparable to the length of the ferry ride from Point Judith to Block Island and back. continued@providencejournal
