Robotic technology is being developed to help rid the reefs of invasive species–the crown of thorns starfish on our side of the world and the lionfish in the Atlantic and Caribbean.
Robot designed to kill the invasive crown of thorns
From Scientific American:
The Great Barrier Reef will have a robotic protector beginning this winter. The underwater autonomous vehicle is programmed to patrol the massive living structure in search of destructive crown-of-thorns starfish (COTS), which it then kills by lethal injection. These starfish prey on coral polyps, and although they are native to the reef, their population has exploded in the past few years, possibly because of overfishing of their natural predators.

Our friends in the Atlantic and Caribbean also have a serious problem with the invasive lionfish. Another robot has been proposed to help with this predator.

From Live Science:
The robotics company iRobot, known for creating the autonomous and endearing Roomba vacuums, is taking steps to make a clean sweep of lionfish in the coastal waters of the Atlantic Ocean, with a robot designed to target and dispatch the invasive fish. Click here to read the full article

Norbert & Simona from Germany enjoyed 3 great days of diving with the Pirates. They are already planning a return trip next year–can’t wait to see you again!
Here’s how the microbeads in your toothpaste or face wash end up in your food
Read more about how these compounds found in a lot of personal products are negatively impacting our oceans. I won’t be buying any more of the face wash that I’ve used for years.

Night dives at Mucky Pirates Bay with the Pirates of Sea Rovers are awesome! We often see frogfish, octopus, sometimes seahorses and other unique night time critters. When you book a dive package of 3 days or more, you will get a free night or shore dive.
Walter from Malaysia went out with dive guide Edi to shoot the creatures of the night here on our house reef. Hopefully Walter will send in some of his photos for us to share.

I had this great idea of doing a weekly Throwback Thursday post, choosing images shot in the same week of a previous year. I found a file of images from 2009 and had several photos ready to post, but then realized that none of these critters are found here in NW Bali (I was living in Grand Cayman then).
So, I had to change my criteria and just picked photos from the past of things that could be found here. So, the photos in today’s post were shot in 2001 when I was on a liveaboard in Komodo. I’ve seen all of them this month on my dives with Sea Rovers.
