Centipede

(Dvd)

The Centipede (Chilopoda) are a class of Arthropods (Arthropoda) and will be attending the Tausendfüßern (Myriapoda) classified. Worldwide, about 3,000 known species of these animals. Thus, they Doppelfüßern according to the second group of Tausendfüßer dar. The animals reach body lengths of 1 to 10 centimetres, tropical species Scolopendra (GV: Skolopender), but also up to 25 centimetres long.

Lifestyles of the Centipede
On their nightly stroll overpower their victims quickly. They either come in the way of a snake or umringeln their prey.

Construction of the Centipede
The Centipede is a summary of four individual groups, which in their morphology vary, so a single description is difficult. Like all members of the Myriapoden the Centipede characterized mainly by a single breakdown of body segments. Even the great Giftklaue, from the first run leg couple was developed in accordance than Maxilliped called, is for all Hundertfüßern to find.

For all groups with the exception of the head Scutigeromorpha is flat. The leading edge is always a connection line between the two antennas, the front shield (Clupeus) is down weggeklappt. In this way, the mouth with the mouth tools on the underside of the head, just before the poison claws. The Mandibeln are at the very Scutigeromorpha vigorously trained and able to Chitinteile to zerbeißen. The 1st Maxilla help with the food intake and keep the particles. The 2nd Maxilla consist only of a button with Halteklaue and a spangenartigen structure. The great poison claws have a strong lead, at the large Giftdrüse ausmündet. You can contact the Scutigeromorpha moving in all directions, with all other groups are replaced by a set and can Hüftplatte only in a level. The poison is in large Scolopendra species can be very unpleasant and even in European Scolopendra cingulata to local paralysis appearances, the last several days.Deaths from the bite of tropical Hundertfüßern are in the realm of legend to ban and were never documented. Nachgesagt, however, that a girl in the Philippines by a head bite died [1]. Components of the poisons can acetylcholine, serotonin and histamine. A few species also produce cyanide. The antennas are on the scourge Scutigeromorpha antennas with two basic terms of (convergence to the antenna of the insects), for all other than they are perlschnurartige limbs antennas trained. Facets eyes only for the Scutigeromorphen, which Geophilomorphen are augenlos and other groups have to point eye-resolution eyes fields, but there are also some blind from these species. You can find Combined sensory organs (humidity, sound, chemistry?) In the form of Postantennalorgane (Tömösvárysche institutions) in the vicinity of the antenna base among Lithobiomorpha and Scutigeromorpha.

The spinal disks (Tergite) vary especially in the Lithobiomorpha in its length (Heterotergie), the Scutigeomorpha covers an especially large plate segments 7 to 9 The Geophilomorphen belong to every segment two rear panels. Overall, the Lithobiomorpha and Scolopendromorpha only 15 pairs of legs, Scolopendromorpha 21 to 23 pairs of legs and the Geophilomorpha leg up to 191 pairs. A common characteristic of all Centipede is an odd number of leg pairs.This is because during the embryonic development of the animals from one body segment always two pairs of legs (four individual legs) show. The first pair of legs is further but to a Giftklaue reshuffle, the first segment is therefore only a pair of legs. All other segments run leg wear two pairs of legs in (the terminal pair is, however, some species more or less reshuffle). The sum is always an odd total number of leg pairs (Current Biology, Vol 14, p. 1250).

The last pair of legs will be run on all Hundertfüßern collected and is sometimes worn specially rebuilt. So it is with the Scutigeromorpha an extended probe antennenartig leg, in some Skolopendra species makes it a strong pliers. Behind this pair of legs run in the following two segments Hundertfüßern still run without legs. These contribute to the Scutigeromorpha two pairs griffelartige gonopods, the female Scutigeromorpha and Lithobiomorpha have a Gonopodenzange.

The Tracheenöffnungen lie with the Scutigeromorpha always behind the dorsal Tergiten, while in all other groups above the legs.
