Plutonium (centipede)
''Plutonium zwierleini'', in the Monotypic taxon, monotypic genus ''Plutonium'', is one of the largest scolopendromorph centipedes in Europe, and one of the few potentially harmful to humans. Nevertheless, it has been rarely reported, only from the southern part of the Iberian Peninsula, Iberian and Italian Peninsula, Italian peninsulas, Sardinia and Sicily. Morphology The body is mainly brown-orange, slightly darker on the head and the most posterior part of the body, including the ultimate pair of appendages. Conversely, the antennae and the walking legs are paler. The body length may surpasses 12 cm, which is the maximum measured from the anterior margin of the head to the posterior tip of the trunk, among the few specimens collected. Even higher measures have been reported in the past. ''P. zwierleini'' is fully blind, without trace of eyes. As in all other centipedes, the first appendages of the trunk are a pair of piercing fangs, which are used to grasp and poison pr ...

Plutonium Zwierleini - Trecastagni - 2 - Lucio Bonato
Plutonium is a chemical element; it has symbol Pu and atomic number 94. It is a silvery-gray actinide metal that tarnishes when exposed to air, and forms a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states. It reacts with carbon, halogens, nitrogen, silicon, and hydrogen. When exposed to moist air, it forms oxides and hydrides that can expand the sample up to 70% in volume, which in turn flake off as a powder that is pyrophoricity, pyrophoric. It is radioactive and can accumulate in bones, which makes the handling of plutonium dangerous. Plutonium was first synthesized and isolated in late 1940 and early 1941, by deuteron bombardment of uranium-238 in the cyclotron at the University of California, Berkeley. First, neptunium-238 (half-life 2.1 days) was synthesized, which then beta-decayed to form the new element with atomic number 94 and atomic weight 238 (half-life 88 years). Since uranium had been named after the planet Uran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scolopendromorpha
Scolopendromorpha is an order of centipedes also known as tropical centipedes or bark centipedes. This order includes about 700 species in five families. These centipedes are found nearly worldwide, with tropical and subtropical regions providing the richest diversity in species. This order includes the only known amphibious centipedes, ''Scolopendra cataracta'', ''Scolopendra paradoxa'', and ''Scolopendra alcyona''.> Description The centipedes in this order are wikt:epimorphic, epimorphic, hatching with a full complement of segments. They usually possess 21 or 23 trunk segments with the same number of paired legs. The number of leg pairs is fixed at 21 for most species in this order and fixed at 23 for the remaining species, except for two species with intraspecific variation: ''Scolopendropsis bahiensis'', which has 21 or 23 leg pairs, and ''Scolopendropsis duplicata, S. duplicata'', which has 39 or 43 leg pairs.

Arthropod
Arthropods ( ) are invertebrates in the phylum Arthropoda. They possess an arthropod exoskeleton, exoskeleton with a cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate, a body with differentiated (Metamerism (biology), metameric) Segmentation (biology), segments, and paired jointed appendages. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. They form an extremely diverse group of up to ten million species. Haemolymph is the analogue of blood for most arthropods. An arthropod has an open circulatory system, with a body cavity called a haemocoel through which haemolymph circulates to the interior Organ (anatomy), organs. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. They have ladder-like nervous systems, with paired Anatomical terms of location#Dorsal and ventral, ventral Ventral nerve cord, nerve cord ...

This family includes more than 90 species. Distribution Most species in this family are found in the Americas (North America, South America, and the West Indies) and East Asia (Japan, Korea, China, Vietnam, the Philippines, and Indonesia). Some species have also been recorded in West Africa (from Guinea and Sierra Leone to Gabon), New Guinea, and Fiji. This family is most diverse and abundant in the New World, especially in the Neotropical realm. Description Species in this family are eyeless and have 23 pairs of legs. The second maxillary claw in these species is pectinate. These centipedes have a forcipular coxosternite without prominent serrate tooth-plates, featuring at most a few shallow teeth. Species in this family feature a dist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taormina
Taormina ( , , also , ; ) is a ''comune'' (municipality) in the Metropolitan City of Messina, on the east coast of the island of Sicily, Italy. Taormina has been a tourist destination since the 19th century. Its beaches on the Ionian Sea, including that of Isola Bella, are accessible via an aerial tramway built in 1992, and via highways from Messina in the north and Catania in the south.

Spiracle (arthropods)
A spiracle or stigma is the opening in the exoskeletons of insects, myriapods, velvet worms and many arachnids to allow air to enter the trachea. Insect respiratory system differs from vertebrates'. The circulatory system plays a relatively minor role in circulating oxygen and removing carbon dioxide; instead, trachea and air sacs in the insect body allow direct gas exchange, and these tracheal tubes eventually connect to the external environment via spiracles. In most species, the spiracles are controlled by motor neurons in the central nervous system. It can be opened and closed in an efficient manner to admit air while minimizing associated physiological costs, such as water loss during respiration. Many sensory stimuli can affect the control of spiracles in insects, e.g. chemosensory (carbon dioxide, oxygen, etc.) or mechanosensory (sound, touch, etc.). It has been shown that during metabolically intensive behaviors, such as flight, insects can dynamically modulate the spir ...
