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.
You can distinguish adult male axolotls from females by their relatively straight bodies and large glands about the cloaca (vent). Mature females have round, plump bodies because they are filled with eggs, and they lack the conspicuous glands. Axolotls cannot be sexed until they are sexually mature, at about one year.
