A vegetarian sap-sucking sea slug that can regrow its entire body? Underwater photographer Wesley Oosthuizen takes a closer look at this curious little marine critter.
The 144-foot Nucleus had a “checkered past” after previously sinking twice, and once rammed and sank another boat on Lake Huron, the Great Lakes Shipwreck Museum said in a news release announcing the discovery.
This is a pretty significant shipwreck…considering its age, the fact that it is a barquentine and we can’t overlook the vessel’s checkered past. The wreck site is littered with shovels too…and a few dinner plates, which speaks to their work and shipboard life.

The US Naval History and Heritage Command (NHHC) confirmed the identity of a wreck site off the coast of Hokkaido, Japan, as USS Albacore (SS 218). The NHHC made the announcement on Thursday, after several months of examining Japanese surveys conducted on the site in 2022.
In the early part of the 20th century, American physicist and chemist, Professor Elihu Thomson—the person credited with putting the eventual use of helium on the diving menu—had originally proposed the use of hydrogen as a suitable replacement for nitrogen in the breathing mix used by divers. David Strike has the story.
As any underwater photographer can attest to, water and electronics do not mix. Despite our best attempts at planning for unforeseen circumstances, the law of averages dictates that things can and will go wrong. More often than not, some situations are ones we had not even considered. Peter Symes and Scott Bennett report.
Effective 14 February 2023, International travelers arriving into Fiji by air or sea will no longer be required to provide proof of COVID-19 vaccination and travel insurance.
It turns out that raising sons takes a higher toll on southern resident orca mothers, when compared to raising daughters. So much so that the mother’s annual likelihood of successfully breeding is reduced by about half.
This is because the mothers share the fish they catch with their sons even after the latter become adults. The mothers would bite the fish they catch into two, consume one half and give the other half to their sons.
(In the case of their daughters, the mothers also share their food, but stop doing so when the daughters reach reproductive age.)
Originally from Zimbabwe, artist Tony Fredriksson is a sculptor based in South Africa who creates incredibly life-like sculptures of marine life out of driftwood, drawing inspiration from how the wood is eroded by weather, scoured by streams or sanded smooth by sand. X-Ray Mag interviewed the artist to learn more about his artworks and creative process.
How much weight should a diver use? How much is too much or too little to maintain proper posture, balance and air consumption? How do you adjust for a new wetsuit? Simon Pridmore discusses weight issues and offers tips and advice.
