“Courting Devil Ray Ballet,” Duncan Murrell — Honda Bay, Palawan, the Philippines

The photo captures spinetail devil rays in rarely observed courtship – with two males pursuing one female.

“Burst,” Tyler Schiffman — Monterey Bay, US

Schiffman says: “I had framed this shot waiting for a sea lion to swim by. After five minutes, one swam up and paused for a few seconds, I took three photos and as rare as it was the moment left in a blink of an eye.”

“Foggy Morning on Adams River,” Eiko Jones — Adams River, British Columbia, Canada

Jones says of the photo: “A lone Sockeye Salmon swims by as wisps of fog cling to the surface in the early dawn hours on the Adams River.”

“Schools of Schools,” Debbie Wallace — Morehead City, North Carolina, US

“As I slowly and cautiously watched, I saw this large female sand tiger shark with her own bait ball entourage just approaching the massive ball,” says Wallace. “I was mesmerized by the entire scene but my brain quickly engaged enough to set up for the shot of her about to enter.”

“Atlantic Spotted Dolphins,” Eugene Kitsios — Bimini, Bahamas

“These intelligent creatures display so much interesting behaviour and in this case they playfully and curiously swimmed by me,” Kitsios says of the image.

“Nemo,” Matteo Visconti — Ishigaki Island, Okinawa, Japan

“The relationship between the ocellaris clownfish that dwell among the tentacles of Ritteri sea anemones is a good example of mutualism,” Visconti says. “The territorial fish protects the anemone from anemone-eating fish, and in turn the stinging tentacles of the anemone protect the clownfish from its predators.”
