Report details possible killer whale predation of hammerhead sharks
An article posted on DivePhotoGuide.com from the Latin American Journal of Aquatic Mammals reveals a possible predatory interaction between killer whales and hammerhead sharks off the coast of the Galápagos islands.
The observation describes an encounter with three killer whales:
A dead female hammerhead shark could be clearly seen lying on the sandy bottom. It was estimated to be 2.5-3m long, compared to the size of the killer whale hovering approximately 3m directly above it. The whale was motionless, in a vertical position, with its rostrum oriented towards the shark…the divers moved closer to attempt to identify the shark species and noticed that the killer whale had begun to chase a small (approximately 40cm) hammerhead shark.
The authors request to be contacted if any photographers or videographers have captured the behavior they describe.

Recall of Oceanic, AERIS dive computers over decompression hazard
Pelagic Pressure Systems has issued a recall for nearly 2,800 dive computers, the Oceanic-brand ATOM 2.0 and EPIC-brand AERIS. The decompression hazard comes from an issue reported where on switching from one gas to another at depth, the dive computer’s display can lock up and not return to the screen showing dive times.
Pelagic received reports of two defective computers, but no injuries have been reported. If you have one of these computers, with a serial number within the range of #0001-#2079 for the Oceanic ATOM 2.0, or #001-#712 for the EPIC AERIS, bring it to an authorized Oceanic or AERIS dealer for a free software upgrade that fixes the issue.

20 new shark and ray species discovered in Indonesia
After a five-year study of catches in Indonesian fish markets, twenty new species of sharks and rays have been discovered. Fourteen species have not yet been described in scientific journals, and the remaining six include the Bali Catshark and Jimbaran Shovelnose Ray.
The study involved sampling over twenty-two different trips across eleven ports in Indonesia, and was designed to help improve the management of shark species in the area. With the number of Wetpixel members traveling to this popular destination in recent months, a few may have inadvertently photographed some of these new species.
