French company #Seabike has developed a swimming device that uses your own leg power to accelerate you through the water at superhuman speeds.
This crank-driven pusher prop looks a bit like an #underwater#unicycle...
The idea is simple enough; you extend the Seabike's pole to the appropriate length, then strap it to your waist with a belt. Then you find the pedals with your feet, and start turning the crank, with the waist strap to push against. https://newatlas.com/marine/seabike-swimming-propeller/
Flashback to when the kid and I waded in falls by Kent Pond in Vermont and I found a trout following us. Into the water with the phone! #fish#photography#underwater
A team of scientists and Alaska Native community members explore the continental shelf west of Prince of Wales Island in southeast Alaska, seeking submerged caves and rock shelters that would have been used by early inhabitants.
A hunting monkey, ‘kissing’ scorpionfish, playful dolphins, a mahi-mahi ambushing sardines…Swim on up to the winners of the 2024 Underwater Photographer of the Year Awards.
I found this medium-sized octopus on a night dive. It was perched on a piece of coral and I wasn't able to immediately recognize what I was looking at. After a moment in the spotlight, the octopus dropped down to the reef and began to move around. After a few minutes, it seemed to adjust to us and go back to hunting. Yay octos!
It's always disappointing to see invasive lionfish on Caribbean dive sites, as they devour the local populations and have few predators. That said, they are visually interesting, with so many different colors and textures warning predators about the venomous spines.
I had never seen this type of anemone before our dive guide pointed it out on a dive in Saba. It is simply called a Branching Anemone and it was spread out over a large area on the surface of some coral. It's always fun seeing a new species, especially when they are so pretty.
