Just one month ago, we reported on the availability of some unusual species offered by temperate marine aquarium livestock specialists Coldwater Marine Aquatics. Apparently quite intent on making inroads into the aquarium hobbyist market, the Oregon-based retailers...
Nudibranch sea slugs are known for being feeding specialists, sometimes eating only a single food item. The predatory Pleurobranchaea californica is a big exception, as it will try just about any food item once. P. californica occurs in deep waters off the western...
Many species of damselfish practice what we may call farming. That is, unlike most herbivores, they do not simply rove about grazing on whatever suitable items they stumble upon; rather, they stake out a territory where there is growth of a desirable algae species,...
Kingman Reef is a 30-mile triangle of coral reefs that is a part of Line Island group. A lagoon formed by the reefs covers an area that is roughly the size of Manhattan Island. Lying near the Equator, about 1,000 miles south of the Hawaiian Islands, Kingman Reef is...
Many of us have for long been familiar with the fundamentals of hydroponic gardening; in short, plants are continuously watered and fed via a recirculating water system. In some cases, water-based horticulture can be enhanced by integrated production methods. One such...
The ikan kelah, or red mahseer, is a cypriniform fish that is found in cool, fast and clear waters from the Himalayas to Afghanistan, Pakistan, India, Bangladesh, Nepal, Myanmar, Sri Lanka, Thailand, Cambodia, Laos, southern China, Vietnam and Indonesia. However, it...
As anyone who has ever kept it with their goldfish knows, the aquatic plant hornwort (Ceratophyllum submersum) is really tough. It thrives in virtually all conditions, reaching extraordinary growth rates when exposed to intense illumination. And, its rigid, spindly...
The USCGC Mohawk WPG-78 was launched in 1934. The 165-foot vessel saw a considerable amount of service, including World War II combat operations in the North Atlantic. In more recent days it had been docked in Fort Meyers Beach, Florida. On July 2, 2012, after being...
It is probable that sound plays just as important a role in shaping aquatic ecosystems as it does in terrestrial ecosystems; after all, water conducts sound waves with much more intensity than does air. However, the higher conductivity of water actually makes it...
We’ve heard a lot lately about how carbon dioxide emissions are contributing to global warming, which is ravaging (among other habitats) tropical coral reefs. Over the last 40 years, a secondary (though equally potent) carbon-related threat to coral reefs has emerged:...
