Get Rid Of House Centipedes
Over twelve thousand species of the arthropods centipedes and millipedes are known. Centipedes are carnivorous, and millipedes are usually vegetarians. Centipedes and millipedes are somewhat similar organisms. Together, they make up approximately twelve thousand species of long, flattened, segmented animals, grouped among the Myriapods. A major difference between centipedes and millipedes is diet. Centipedes are carnivores, living on other animals, and millipedes are herbivores, living on dead plant matter. Millipedes have cylindrical bodies, while centipedes are wormlike. When a centipede or millipede runs, it picks up each leg, one after the other. However, it only moves the legs on one body side at a time. The result is that legs move in rhythmic waves along the body. Millipedes are much slower than centipedes. Physical Characteristics of Centipedes Centipedes belong to the class Chilopoda of the phylum Arthropoda, which includes insects, myriapods, crustaceans, and spiders....

Associated with the plants in the Early Devonian Rhynie Cherts, mentioned above, several groups of freshwater animals like arthropods were found such as spiders, mites, and centipedes. These animals were carnivores (eating other animals) and dentritivores (eaters of dead and partly decomposed plant parts) but not herbivores (eaters of living plant tissue). While most of the organs and tissues of the early land plants had to be newly developed, early land animals resembled closely their aquatic ancestors. In their multiple transition to the land they retained most of their complex organs, although in modified form. However, animals following the plants onto the land had to face similar difficulties (gravity, motion over rough soil, respiration, desiccation, reproduction) as the plants.
Many of the early arthropods vaguely resemble today's sow bugs, shrimp, centipedes, and horseshoe crabs. A very successful group of marine arthropods that superficially resemble sow bugs were the trilobites. A trilobite had a prominent, centrally located, segmented, concave, dorsal ridge running the full length of its body. The trilobites differentiated and evolved for over 300 million years until the few remaining forms went extinct during the Permian-Triassic mass extinction (250 million years ago) that wiped out nearly 90 percent of all species. A trilobite had a head, thorax-abdomen, and tail (pygidium). The segments of the head were fused but the thoracic-abdominal and tail segments were varied. Depending upon the trilobite, thoracic-abdominal segments ranged from nine (low of six) to thirteen (high of twenty-two) in number, whereas tail segments varied from six to sixteen (high of twenty-two). Legs and other specialized appendages protruded ventrally from the segments. Gills...
Research on insects and associated arthropods (e.g., spiders, mites, centipedes, millipedes, crustaceans) has been critical to development of the fundamental principles of ecology, such as evolution of social organization (Haldane 1932, Hamilton 1964, E. Wilson 1973) population dynamics (Coulson 1979, Morris 1969, Nicholson 1958,Varley and Gradwell 1970,Varley et al. 1973,Wellington et al. 1975) competition (Park 1948, 1954) predator-prey interaction (Nicholson and Bailey 1935) mutualism (Batra 1966, Bronstein 1998, Janzen 1966, Morgan 1968, Rickson 1971, 1977) island biogeography (Darlington 1943, MacArthur and Wilson 1967, Simberloff 1969, 1978) metapopulation ecology (Hanski 1989) and regulation of ecosystem processes, such as primary productivity, nutrient cycling, and succession (Mattson and Addy 1975, J. Moore et al. 1988, Schowalter 1981, Seastedt 1984). Insects and other arthropods are small and
The smaller forms of animals that are considered useless or harmful are described as kachirombo (ka, diminutive plural, tizirombo), and this term thus comes to cover a wide variety of small animals - insects, millipedes, centipedes, scorpions, spiders and crustaceans. Insects may thus be glossed as kachirombo - although edible insects like the cicada (nyenje), winged termite (ngumbi) and locust (dzombe), while important as relish, are not usually described as nyama, nor are they usually thought

Polis (1991b) and Reagan et al. (1996) reported the occurrence of a substantial number of loops, especially involving arthropods. In most cases, each species in the loop preys on juveniles of the other species. For example, in a tropical forest in Puerto Rico, adult centipedes prey on young frogs, whereas adult frogs prey on young centipedes. Polis (1991b) reported that several species of desert ants regularly prey on each other. Other predators constituted 9 of the overall diet of the aquatic heteropteran, Notonecta hoffmanni, studied by Fox (1975b). Longer loops involving up to four species have been observed (Reagan et al. 1996). Reagan et al. (1996) found that 35 of 19,800 observed chains (corrected to exclude loops) include at least one species involved in at least one loop.
American short-tailed shrews inhabit southeastern Canada, the northeastern United States, Texas, and Louisiana. They have thick, gray-black fur, are four to five inches long, have one-inch tails, and weigh one ounce. Like other shrews, American short-tailed shrews constantly seek food, eating insects, earthworms, snails, small vertebrates, centipedes, spiders, mice, frogs, and plants. They have venomous saliva, used to stun and kill prey, which is also painful to humans and large animal predators. Predators of the shrews are owls and other raptors.
From seaside vacations we can recall that gravity is particularly felt when getting out of the water. In water, buoyancy working on a body with air-filled pockets (for example the air-bladders of fish or air-sacs of brown algae) greatly decreases weight. A second severe problem on land, other than in the ocean or even on the sea floor, is that it is difficult to move on dry soil. Here plants chose to avoid movement entirely and remain stationary. But how could then a plant at a fixed position on land obtain its necessary supply of water and essential nutrients Some animals such as the arthropods (spiders, centipedes, insects, crustaceans), that probably had evolved from walking worms on the sea floor, did not have to modify their appendages much to move on land, while the need of locomotion for vertebrate animals (chordates) required more extensive skeletal developments.
Centipedes, millipedes, and the two other groups of animals comprise the phylum Myriapoda. Centipedes and millipedes have a well-formed head and a long, flexible, segmented trunk that bears many pairs of legs (Figure 33.15). Centipedes, which have one pair of legs per segment, prey on insects and other small animals. Millipedes, which have two pairs of legs per segment, scavenge and eat plants. More than 3,000 species of centipedes and 10,000 species of millipedes have been described many more species probably remain unknown. Although most myriapods are less than a few centimeters long, some tropical species are ten times that size.
Although people throughout the world (and Malawians are no exception) clearly recognize distinctions between animals and plants, this is rarely given significance in folk terminology. Many people thus have no terms for the 'animal' and 'plant' kingdoms. It has been suggested that both these concepts are relatively recent phenomena in the development of taxonomic nomenclature (Berlin 1972 Morris 1980). But throughout the world people have higher-order categories, generally referred to as 'life-forms', that embrace a diverse number of folk generics. Their number is usually small, and includes such taxa as 'bird', 'fish', 'tree', 'herb' and 'quadruped'. The Ndumba of Papua New Guinea, for example, have an animal taxonomy that includes four life-forms - fai (marsupials and monotremes), kaapa'raara (reptiles, eels, centipedes and worms), Kuri (bats and birds) and tovendi (insects and arachnids). These include most of the folk generics (Hays 1983 602). Unlike folk generics, which as...
The phylum Arthropoda is the largest phylum in the animal kingdom and consists of myriad animals belonging to the subphyla Trilobita (extinct trilobites with biramous antennae, probably all marine), Chelicerata (horseshoe crabs, scorpions and pseudoscorpions, spiders, harvestmen, mites, ticks, and marine pycnogonids all lacking antennae), Crustacea (all with biramous antennae), and Uniramia (insects, centipedes, millipedes all with uniramous antennae). All of these subphyla are united by a common body plan similar to that of the annelids, in which the body is made up of a series of repeating segments, each bearing a pair
There are over one thousand species of true bugs, many strikingly colored. These include stinkbugs, water bugs, cotton-stainer bugs, and assassin bugs. At least twenty thousand species of beetles exist. These are colorful and varied in appearance, with descriptive names such as jewel-beetles, longhorn beetles, tiger beetles, darkling beetles, scarabs, and the bizarre giraffe-necked weevils. Madagascar has hundreds of moth and butterfly species, including many varieties of swallowtails and the attractive pansy butterflies. Hundreds of species of wasps and bees live in Madagascar, and several have bright metallic green coloring. Of the remaining invertebrates, there are many worms, leeches, and flatworms, and a huge variety of endemic land snails. There are about 430 species of spiders, 12 species of scorpions (only two have a painful sting), 64 species of centipedes, and also many millipedes, some reaching giant sizes of six inches or more.
The diet of meerkats consists largely of whatever is available in the harsh desert habitat. Insects, spiders, centipedes, scorpions, lizards, snakes, small mammals, birds and their eggs, roots, tubers, and other plant matter are all staples of the meerkat diet. Each individual takes its turn
Animalia (from a Latin word meaning soul or breath ) is the kingdom with the largest number of life-forms, from Placozoa, a phylum with a single species usually found growing on aquarium walls, to the phylum Arthropoda (from a Greek word meaning jointed foot ) that contains more than a half million identified species, including spiders, scorpions, beetles, shrimp, lobsters, crayfish, crabs, flies, centipedes, millipedes, butterflies, moths, and all other species of insects. Seventeen of the thirty-three phyla in Animalia are various kinds of worms found in the shallow and deep water of lakes, rivers, and oceans and in the ground. One worm phyla, Pentastoma, consists of more than seventy species that live exclusively in the tongues, lungs, nostrils, and nasal sinuses of dogs, foxes, goats, horses, snakes, lizards, and crocodiles. Another phyla, Platyhelminthes, consists of worms that live in bat dung and other
Crabs and lobsters are joint-legged animals that belong to the phylum Arthropoda. This diverse phylum of animals also includes the insects, spiders, ticks, mites, millipedes and centipedes. Phylum characteristics include a chitinous exoskeleton, jointed appendages, a ventral nervous system, and a dorsal brain. Both crabs and lobsters are crustaceans, which are placed in the class Malacostraca along with the shrimp. Crabs differ from lobsters in having a broad upper shell or carapace and an abdomen that is shorter and either tapered or tucked forward beneath the carapace.
