Unusual Orange Sponge: Myripristis jacobus

Good morning friends, today we have two sub dives, the first starting at 9:00. I’m going to have my young intern shoot a go-pro movie of me photographing the sub today and I will try and post that as soon as I can. I have a KILLER, ultra unusual orange sponge for you all today that we found years ago growing in a small cave. To this date this is the only one of these we have ever seen and we visit it on almost every dive. You can kind of get an idea of the size of the sponge by the little seven-inch Cardinalfish above who we think has adopted the sponge and the cave as his own.  MORE

Aquarium Technologies Borrowed from Other Industries

Actinic lighting was developed and used in other industries before reef aquariums

 We marine aquarists use a variety of tools to help keep our tanks healthy by either changing the water or removing the waste products of the animals we keep. But did you know virtually all of the devices we use were originally designed for other industries? Ozone: For instance, ozone is a naturally forming gas found in our atmosphere that helps protect us from the damaging effects of the sun’s ultraviolet radiation. It was discovered in 1839 by Christian Friedrich Schönbein. Ozone was originally used to purify drinking water and as a health-giving gas. Unfortunately, that health idea produced just the opposite result because the oxidizing effect we can use to purify certain things will also oxidize us, especially our lungs. MORE

Hope For Coral Reefs In Lab Grown Corals

It comes as no surprise that corals are under more stress than ever. It is a very troubling problem we hear about day in and day out. Global warming, overfishing, dredging, pollution, human influence and disease outbreaks are all to blame. For example, critically Endangered Elkhorn Caribbean coral has diminished its population by ninety eight percent. Coral conservation needs to be on the forefront of all of our minds.
Luckily, there is some good news too. New research was published recently in the Bulletin of Marine Science which shows that lab generated corals are able to withstand and thrive when placed in the increasingly stressed natural environments. Scientists took fertilized eggs from a Curacao coral reef, brought them back to an offshore lab until they were fully matured. The larger grown corals were then placed back into their natural re, and a year later, were observed releasing eggs and sperm. MORE
