Crustaceans (Crustacea) form a very large group of arthropods‚ usually treated as a subphylum‚ which includes such familiar animals as crabs‚ lobsters‚ crayfish‚ shrimp‚ krill and barnacles. The 67‚000 described species range in size from Stygotantulus stocki at 0.1 mm (0.004 in)‚ to the Japanese spider crab with a leg span of up to 12.5 ft (3.8 m) and a mass of 44 lb (20 kg). Like other arthropods‚ crustaceans have an exoskeleton‚ which they moult to grow. They are distinguished from other groups

Binayuyu (Antidesma ghaesembilla Gaertn var. ghaesembilla) is a herbal plant used by B’laan tribes in the southern part of the Philippines. It is said that it can cure stomach ache and helps to lower blood sugar. Artemia is a genus of aquatic crustaceans known as brine shrimp. Artemia‚ the only genus in the family Artemiidae‚ has changed little externally since the Triassic period. The historical record of the existence of Artemia dates back to 982 from Urimia Lake‚ Iran‚ although the first unambiguous

which is the marine arthropods. The Horseshoe Crab’s closest relatives are Trilobites back from the Paleozoic which is coincidently when the Horseshoe crab first began to develop. (Reference 2) In modern times the Horseshoe crab is not labelled as a crustacean despite its name. The Horseshoe Crab is closely related chelicerates including spiders‚ ticks‚ and scorpions than real crabs. (Reference 3) The characteristics of chelicerates are a segmented body‚ a chitinous exoskeleton‚ molting‚ and jointed legs

Abstract Biomimicry (from bios meaning life and mimesis meaning to imitate) is a design principle that seeks sustainable solutions to human problems by consulting and emulating nature’s time tested pattern and strategies. According to biologist Janine Benyus (2002)‚ author of the groundbreaking book Biomimicry‚ the core idea is that nature‚ imaginative by necessity‚ has already solved many of the problems designers are grappling with. Biomimicry is applicable in many important things such as‚ in

Description: Slaters are apart of the Isopoda order‚ meaning they have an equal number of legs. They are also a crustacean‚ but unlike most crustaceans they are terrestrial opposed to marine dwellers so they fall into the Oniscoidea suborder. They have very distinct features like their elliptical flattened segmented exoskeleton and seven pairs of legs. They generally are dull in colour

http://en.wikipedia.org/wiki/Woodlouse A woodlouse is a crustacean with a rigid‚ segmented‚ long exoskeleton and fourteen jointed limbs. Woodlice form the suborderOniscidea within the order Isopoda‚ with over 3‚000 known species. The woodlouse has a shell-like exoskeleton‚ which it must progressively shed as it grows. The moult takes place in two stages; the back half is lost first‚ followed two or three days later by the front. This method of moulting is different from that of most arthropods

As you can guess‚ Arachnids are arthropods with eight legs. Most Arachnids live on land‚ but there are few who live in freshwater. Another arthropod species is crustaceans. Crustaceans have ten or more legs and most of them are aquatic. The most widely known crustaceans consist of shrimp‚ lobsters‚ and crabs. There are a few crustaceans‚ like woodlice‚ live on land rather than in the water. Being the largest phylum in the animal kingdom‚ arthropods are very critical to the animal world. An example

The group contains familiar popular marine food animals such as lobsters‚ crabs‚ and shrimp. While mainly found in salt and freshwater environments‚ there are also terrestrial Crustacean such as woodlice and isopods. Crustaceans have three distinct body parts: head‚ thorax‚ and abdomen (also called a pleon). Excretion is the removal

most of which are active hunters that attack and kill their food. Vampire squids are definitely not that‚ as Hoving and Robison confirmed by checking the stomachs of captured specimens. They found eggs‚ algae‚ pellets of faeces‚ bits of jelly‚ crustacean body parts—antennae‚ eyes‚ some shells‚ whole copeopods—and flesh from another deep-sea squid. In both kind and quantity‚ these remnants don’t reflect the diet of a hunter. Instead‚ Hoving and Robison think that the vampire squid is mainly a ‘detritivore’
