  1. Mollusks add daily to the margins of their shells, producing intricate patterns prized by beachcombers. Though this seems complex, the process can actually be explained by a simple network of nerve cells that sense or "taste" yesterday's shell layer in order to build today's. In essence, seashell patterns are a hard copy of a snail's memories. To prove it, researchers created a computer program that re-creates the patterns seen in seashells.

  2. When animals first crawled onto land, one of the greatest obstacles they had to contend with was figuring out how to breathe. No longer bathed in oxygen-rich marine waters, their gills would surely have dried out. Scientists have analyzed fossils from 500-million-year-old rocks that show one way these early pioneers may have dealt with this problem--the first terrestrial animals carried a shell on their backs.

  3. The International Polar Year concluded in March 2009 with a tangible legacy in the form of a network of databases on marine biodiversity that will serve as clearinghouse for all biodiversity-related data gathered since the very first Antarctic research expeditions. The network gathers data describing the species themselves as well as information about their collection history, allowing scientists and conservationists to access the first rigorous census of Antarctic marine life.

  4. Hi Achilles Tang, so is it the best to invest a chiller ? to keep the temp low 28'C ? currently my temp shot up to 30-31.5'C :cry: and what hosepower chiller should I use ? look for the buget one ?

    31.5C is very scary....

    You really ought to try using a fan at least to increase evaporation if you can't afford a chiller.

  5. Higher temps increases the toxicity of waste materials. Also brings reduced oxygen levels. It also makes the metabolic rates of livestock increase. All bad.

    It's possible but not recommended. It's a fine balance but a slight tilt could crash the system if lets say your pumps overheats or your MHs stay on for a long time.

  6. Seahorses are a lot more demanding than you think.

    They eat non-stop and need the right kind of foods... ie. live shrimps. Unless they are trained or YOU train them yourself intensively until they do.

    Water quality has to be good too.
