The phylum Arthropoda includes the classes Diplopoda (millipedes), Chilopoda (centipedes), Crustacea (see Chapter 3), and Insecta (see Chapter 1). All luminous arthropods other than crustaceans are terrestrial, and not very many luminous millipedes and centipedes are known. The luminescence of millipedes is usually intracellular, whereas luminous centipedes discharge luminous secretion. Substantial chemical studies have been made only with the millipede Luminodesmus sequoiae and the centipede Orphaneus brevilabiatus, of which the latter is discussed in the Section 10.3. 

According to Haneda (1955), the centipede Orphaneus brevilabiatus is found widely in Micronesia, the East Indies, the Malay Peninsula, Indochina, Formosa and Okinawa. The centipedes (about 6 cm long) are often found in native houses, on the walls and inside furniture, and they secrete a greenish luminous slime when irritated. When exposed to a chloroform vapor, they discharge strikingly luminous slime from every segment of the body.

Despite the fact that Milner s theory was originally developed for miktoarm-star copolymers, it can also be adopted for more complex branched structures. This empirical concept termed constituting-block copolymers approximates the architecture of branched molecules to be composed of an array of A2B and A2B2 miktoarms. This approach is capable of predicting the morphology of architectures as complex as centipedes or barbed wires, as shown in a very recent publication [125].

The production of HCN by animals is almost exclusively restricted to various arthropods 7 species of about 3000 species of centipedes 46 of 2500 species of polydesmid millipedes and 10 of 750,000 species of insects, including 3 species of beetles, 4 moths, and 3 butterflies (Duffey 1981).

On weed-free ground, a loose mulch, 4 in (10 cm) deep, will provide effective weed control. Any weeds that may appear are easily removed. An organic, biodegradable material is the preferred organic option as a bonus, this sort of mulch will attract beetles, centipedes, and other pest-eating creatures that enjoy the dark, moist conditions. 

Winter digging can expose overwintering pests for predation by birds and ground beetles. However, don t go too far when tidying up the garden spare a thought for the beetles, centipedes, and toads that play a vital role in pest control. They need safe, undisturbed locations to thrive. 

A woodchip or bark mulch will shelter beetles, centipedes, and the like, while thicker mulches of hay and straw may be frequented by frogs, toads, shrews, and spiders. In winter, try to leave some areas of mulch undisturbed for creatures to hibernate in. 

The investigation carried out on some Chinese animals used for CNS symptoms similar to those seen in AD resulted in the isolation of long chain fatty acids from the centipede Scolopendra subspinipes mutilans which had weak AChEl activity.A series of fatty acids was tested to discern any structure-activity relationships and it was found that only free acids, not esters, had AChEl activity. The presence of unsaturated bonds and a chain length of not less than 16 C were was necessary for activity. The most active compound tested was linolenic acid (71) with IC50 of 59.9 xM against AChE. 

Insects, spiders, scorpions, crabs, centipedes, millipedes, and even some plankton are arthropods, the largest and most diverse animal phylum. Some are capable of producing very powerful toxins as an aid in the quest for food. Humans come in contact with these toxins, usually by accident or as a result of the animal defending itself. Some insects, mosquitoes and ticks for example, are capable of transmitting other organisms to humans that cause disease. While these organisms may be toxic to humans, they are not toxins and will not be discussed in this chapter.
