Hive management genetics of the queen. Queens and drones are selectively bred to increase the production of royal jelly. A good yield per hive is 5 kg per year. Bee venom (apitoxin) is obtained by stimulating the bee with an electric current that incite them to sting, releasing a drop of poison onto a glass slide. The crystallized venom can be collected and processed. In order to get 1 gram of dry venom, it is necessary to collect the apitoxin of 10,000 to 15,000 bees. Bee brood as such is generally not a commercial commodity. However, bee brood is edible, and is
Venom (over 80 species), gurnard perches, blennies, rabbitfishes, surgeonfishes, some velvetfishes, some toadfishes, coral crouchers, red velvetfishes, scats, rockfishes, deepwater scorpionfishes, waspfishes, weevers, and stargazers. Among amphibians, some salamanders can extrude sharp venom-tipped ribs. Some 450 species of snake are venomous. Snake venom is produced by glands below the eye (the mandibular gland) and delivered to the victim through tubular or channeled fangs. Snake venoms contain a variety of peptide toxins, including proteases, which hydrolyze protein peptide bonds, nucleases, which hydrolyze the phosphodiester bonds of DNA, and neurotoxins, which disable signalling in the nervous system. Snake venom causes symptoms including pain,
