Amazing Shark Vision Camera

bio sharkScientists have developed a ‘shark vision’ camera that allows us to see just how swellsharks and chain catsharks are able to view their underwater world. Both species of sharks have  brightly fluorescent properties, essentially meaning that these sharks are able to absorb external light and emit it in a different color. Scientists studied the low light photorecepters in the eyes of both species, which enables the sharks to detect light of certain wavelengths. Based on that information, the scientists were able to build a camera that uses the same wavelengths, allowing the scientists to see the underwater world from a sharks eye perspective.

How To Eliminate and Prevent Diatoms in a Reef Tank

Diatoms - reefs
Ok, first of all, what are they? Well, diatoms are a brown algae that typically appear in a reef tank that has just completed its cycle but they can also appear in an established reef tank. They can cover sand, rock, pumps, glass, you name it. Diatoms look ugly but in most cases they are harmless so the key is to not panic when they appear. Diatoms feed mainly off of silicates but also consume dissolved organic compounds, phosphate and nitrates. Unfiltered tap water can contain silicates and is a good way to jump start a bloom if you use it to mix salt or to replace water that evaporated from the tank. The best way to prevent this from happening is to filter water through a RODI unit MORE

Caribbean Reef Octopus Living in Discarded Trash

Good morning friends, I have a very small Caribbean Reef Octopus peering out of the end of a metal pipe for you today that I found during the day out in the middle of the sand. As many of you already know octopus have this amazing ability to squeeze themselves into the smallest of spaces, that’s why I tell all my divers to check every piece of trash they find. Many times in the sub we have seen octopus hiding inside discarded bottles using them as their home, talk about a tight fit?? I found this one above in the mouth of an old metal plumbing pipe just hanging out watching reef creatures swim by without a care in the world. The opening of the pipe is about 3-inches giving you a pretty good idea of his or her size MORE

Can VR oceanic experiences, replace the desire for private and public aquariums?

riftblogpierre1I spend a lot of time researching. In fact, it consumes the vast majority of my time. As a science fiction writer, I am always looking for new material. Research takes me to websites catering to underground conspiracy theorists, all the way up to online astrophysics courses offered by major universities. Often, it’s simply jumping from rabbit hole, to rabbit hole, chasing a lead of information until it either escapes, or ends up the premise of a book. I research the aquarium world with the same veracity. Everything from the social implications of keeping reef tanks, all the way down to ground breaking new methodologies. Since the start of the anti-aquarium movement, I’ve spent a lot of time hunting down information about societies’ views of marine aquariums. This includes both public and private tanks, and how humanity interprets the hobby. Are they viewed as educational and beneficial, or are they seen as animal and environmental abuse? MORE

Freed Aquarium Dolphin Spotted With Baby In Wild

dolphin-captive-wild-calf.adapt.1190.1A dolphin which was released into the wild in 2013 has been spotted in a pod of 55 dolphins off the coast of South Korea. More importantly, she was spotted with a baby at her side. The Indo-Pacific dolphin was known as Sampal when she was in captivity at the Jungman Pacific Land Marine Park in Jeju. She was also featured in a National Geographic article about whether it was possible to reintroduce captive animals into the wild.  Reintroducing captive animals into the wild has been a source of much controversy. There have been lots of studies attempting to capture the success and failure rate of reintroduced animals into the wild. MORE

World Wide Corals Visit

Some stunning chalice corals

 This past weekend, we were at Reef-A-Palooza Orlando and decided to drop in to see Lou, Vic and the team at World Wide Corals. While I was looking at all of the beautiful displays and the World Wide Coral Farm I bumped into Frank Lim from Real Reef Rock.  These are a few shots that Frank and I took with our phones using a yellow filter to counteract the 20K lighting.  It’s pretty amazing how far along our camera phones have come.  If you’re ever in the Orlando area, I highly recommend stopping by their shop.  Plan to stay a while!

Alaska SeaLife Center Using Ocean Water For Heat

img_4913_1_1_The Alaska SeaLife Center (ASLC) has issued a release announcing the use of a CO2 refrigerant heat pump system, which will shift 98% percent of the centers heating use from fossil fuel to salt water. “This project reflects the core mission of the Alaska SeaLife Center “to generate and share scientific knowledge to promote understanding and stewardship of Alaska’s marine eco-systems,” said Darryl Schaefermeyer, ASLC Special Projects Director. “It illustrates the broad and tangible ways in which our day to day work can contribute to the long term health and sustainability of the City of Seward, the State of Alaska and the global community.” The system was in development for over seven years, and after completing two phases, water is pumped in from Resurrection Bay in order to heat the 120,000 square foot building.

Terminal Phase Sleeping Stoplight Parrotfish

Terminal phase stoplight parrotfish under gorgonian. Sparisoma viride. Curacao, Netherlands Antilles. Unaltered/Uncontrolled. Medium Format (horizontal). Model Release: Not Applicable.Good morning all, do you remember my 10 deep-sea fish stamps from 2014? Well, I have more coming out, but this time instead of fish it will be all kinds of cool creatures, most found by our friends at the Smithsonian Institution. When I get the OK I will send them to you, but I am guessing that we will have to wait until they are officially released, stay tuned. I have a sleeping Stoplight Parrotfish for you all today that we found late at night underneath a swaying gorgonian. If you look carefully you will notice a bunch of brown blotchy spots all over the body, those are not there during the day, only at night. “Why?” you ask? Well, it’s a way to help them blend in, making themselves darker or a kind of camouflage if you will and itworks really well. Aimee and I love to seek out as many sleeping parrotfish as we can when night diving. Our goal is try to find those that are either the most hidden or those that lay out in plain sight, they really are amazing fish and super fun to watch.
