COOL CRUSTACEANS
We love crustaceans, one of the big groups of arthropods. They have crabs, lobsters, shrimp, and barnacles. You'll find all of them living in the water or in very wet environments.
Crustacea
Head and thorax fused into a cephalothorax.
At least 40,000 species.
Most are aquatic, found in both fresh water and in the oceans.
Includes crayfish, lobsters, barnacles, crabs, shrimp.
crustaceans A large taxonomic class of arthropods that includes lobsters, shrimps, and crabs.
cuticle A film composed of wax and cutin that occurs on the external surface of plant stems and leaves and helps to prevent water loss.
Crustacea
class in the phylum Arthropoda. Most members of this class are aquatic, although a few are terrestrial.
Crustacean: Any of a zoological class (Crustacea) that have a chitinous and/or calcareous exoskeleton (lobsters, shrimps, crabs).
[edit] Crustaceans
"Marmorkrebs" are parthenogenetic crayfish that were discovered in the pet trade in the 1990s (Scholtz et al. 2003). This is the only known decapod crustacean species to reproduce by parthenogenesis.
crustaceans (subphylum Crustacea)Arthropods that have two pairs of
cryptic coloration A color pattern that allows an organism to blend with the surroundings.
1. A crustacean, many varieties of which are edible.
2. An insect, the crab louse, pthirus pubis.

Most crustaceans are free-living, but some are sessile and a few are even parasitic. Some crustaceans filter tiny plankton or bacteria from the water, while others are active predators. A few crustaceans scavenge nutrients from detritus.
Amphipod: A crustacean belonging the Order Amphipoda (cf. Amphipoda).
Amphipoda: An group of crustaceans recognized by their laterally compressed bodies, lack of a carapace, and numerous, differently modified legs (Hayward et al., 1996).

These branches may have separate functions; in crustaceans, for instance, the inner branch of a leg is used for walking, while the outer branch may be paddle-shaped or feathery and often functions as a gill. Contrast with uniramous.
Arthropod: Any of the invertebrate animals (such as insects, spiders, or crustaceans) having an exoskeleton, a segmented body and jointed limbs.
The five main groups are the centipedes, the millipedes, the crustacea (crayfish, lobsters, barnacles, crabs, pill bugs, shrimps), the arachnids (spiders, mites, ticks, scorpions, limulus), and the insects.
