Updates on Swine Flu In Mexico:  May 4, 2009

Since it has shown up on the Yucatan peninsula, divers with Mexican travel plans need to stay current. Two good sites to check for the latest information: the U.S. State Department has created a "Swine Flu Alert" page ( -- if this link doesn't work,follow the link at to give up-to-the-minute travel information, and the Centers for Disease Control is doing the same regarding health and medical information ( By the way, if you buy travel insurance early on in your trip planning, you'll find many policies will allow you to back out for epidemics. If you try to add it later in your plans, you'll probably be out of luck.

Recall On Mares Drysuit Hoses:  May 4, 2009

Swedish dive gear maker Si Tech is recalling its' low pressure inflation hoses that are used in Mares drysuits. The plastic flow-restricting insert (colored blue, black or green) in the hose may dislodge from the connection valve, potentially obstructing the air flow. Affected hoses were sold between 2006 and 2009 in 15 types of Mares drysuits, including the Dryfit, Icefit and Polarfit models. Send the recalled inflator hoses back to the dealer you purchased your drysuit from, or to a Mares' service center, so the insert can be removed free of charge. For more information, contact Mares Customer Service at 203-855-0631 or e-mail

Dive Operators and Instructors, We Need Your Help:  May 4, 2009

Reader Mike Boom suggested an interesting spin on our Reader Reports -- ask the dive operators for reviews. "One of my favorite conversations with a dive boat or dive resort manager is to ask about the worst or weirdest customers they've had. That's when the really funny stories come trotting out, like the nudist dive charters, the Russian mafiosos with prostitutes in tow, animal pesterers who get bitten in return." So, dive operators and instructors, turn the tables and tell us your entertaining stories that would amuse and inform our readers. E-mail me at, and we'll compile the tales for an upcoming issue.

Lobsters and Crabs Do Feel Pain:  May 4, 2009

A study to be published in the journal Animal Behavior says crustaceans do feel pain and stress, adding to growing evidence that all animals, even shellfish, can suffer. Lead author Robert Elwood collected hermit crabs from rock pools in Northern Ireland and gave some of them small electric shocks. When he provided vacant shells, only the shocked ones left their old homes for them, showing stress-related behaviors like grooming their abdomens and rapping them against the shell. "Grooming is a protective motor reaction, like licking a burnt finger, and viewed as a sign of pain in vertebrates," Elwood wrote. The fact that they showed signs of physical distress at the same time they changed a behavior -- moving into another shell -- suggests they feel pain, too. All the crabs survived and were put back in the rock pools.

Read About a Better Way to Find Lost Divers:  May 4, 2009

In our March issue, we reported on two American divers who got separated from Mike Ball Expeditions' liveaboard Spoilsport and treaded water for seven hours in the Great Barrier Reef. To prevent repeats of that incident, Mike Ball has been testing a new method it invented for locating missing divers at sea. Trevor Jackson, the Spoilsport captain who led the tests, sent us a full report, which you can read at Undercurrent.
