The spanning tree protocol and algorithm were developed by a committe of the IEEE. Currently, the IEEE is attempting to institute enhancements to the spanning tree algorithm that will reduce network recovery time. The goal is to go from 30 to 60 seconds after a failure or change in link status to less than 10 seconds.
Axolotls eat worms, insects, small fish, and just about anything else that can fit inside their mouth and swallow whole, including other salamanders. In the lab, axolotls are fed brine shrimp, California blackworms (Lumbriculus varigatus), and salmon pellets. Terrestrial salamanders are fed crickets, worms, and beef liver. In the Ambystoma Colony, aquatic salamanders are fed food pellets.
1 A healthy axolotl can grow up to 15 inches (30cm) and can live for 20 years. So think carefully before getting an axolotl.  An axolotl is capable of regrowing limbs (and even organs!) and a loss of a limb or gill is not lethal as long as the injury is not too large.
