They are found worldwide in saltwater, though not in oceans. Artemia is a well known genus as one variety, the Artemia nyos, a hybrid of Artemia salina, are sold as novelty gifts, most commonly under the marketing name Sea-Monkeys. Artemia were first discovered in Lymington, England in 1755. There are mixed views on whether all brine shrimp are part of one species or whether the varieties that have been identified are properly classified as separate species. Un-hatched brine shrimp are metabolically inactive and can remain in total stasis for several years while in dry oxygen-free conditions, even at temperatures below freezing. This characteristic is called Cryptobiosis meaning "hidden life" (also called Diapause). Once placed in water, the cyst-like eggs hatch within a few hours, and will grow to a mature length of around one centimeter on average. Brine shrimp have a biological life cycle of one year. This short life span, and other characteristics such as their ability to remain dormant for long periods, have made them invaluable in scientific research, including space experiments. *Pictured are the shrimp with the eggs visible in the bottom shrimp.

Copepods Copepods are a group of small crustaceans found in the sea and nearly every freshwater habitat. Many species are planktonic, but more are benthic, and some continental species may live in limno-terrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds and puddles, damp moss, or water-filled recesses (phytothelmata) of plants such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Some copepods are parasitic and attach themselves to fish, sharks, marine mammals, and many kinds of invertebrates such as molluscs, tunicates, or corals. Our copepods are freshwater only.

Crayfish Live Crayfish, sometimes called crawfish, or crawdads are freshwater crustaceans resembling small lobsters, to which they are closely related. They are found in bodies of fresh water that do not freeze to the bottom, and which have shelter against predators. Most crayfish cannot tolerate polluted water, although some species such as the invasive Procambarus clarkii are more hardy. Some crayfish have been found living as much as 3 m (10 feet) underground.

Daphnia Daphnia are small, mostly planktonic, crustaceans, between 0.2 and 5 mm in length. Daphnia are members of the order Cladocera, and are one of the several small aquatic crustaceans commonly called water fleas because of their saltatory swimming style (although fleas are insects and thus only very distantly related). They live in various aquatic environments ranging from acidic swamps to freshwater lakes, ponds, streams and rivers. Daphnia Doze - A solution for quieting the movement of daphnia.

Fiddler Crabs A fiddler crab, sometimes known as a calling crab, may be any of approximately 97 species of semi-terrestrial marine crabs within the genus Uca. Belonging to the family Ocypodidae, fiddler crabs are most closely related to the ghost crabs of the genus Ocypode. Found in mangroves and on sandy or muddy beaches of West Africa, the Western Atlantic, Eastern Pacific and Indo-Pacific, fiddler crabs are easily recognized by their distinctively asymmetric claws. It is the males which boast an oversized claw or cheliped; it plays a role in courtship and signalling among conspecifics. The movement of the smaller claw during feeding, from the ground to the mouth, inspired the crabs' common name; to many, it appears as if the animal is playing a fiddle (the larger claw).

Gammarus (amphipods) Gammarus is a small invertebrate, approximately 1 cm in length. Its green-grey body is segmented with several jointed appendages and two larger antennae near the head. As with all members of the Malacostraca, Gammarus has mouthparts located at the head segments, with their legs branching from each thoracic section, and most of their abdominal sections. These are freshwater gammarus.

Hermit Crabs Hermit crabs are decapod crustaceans of the superfamily Paguroidea, distinct from the true crabs in the infra-order Brachyura. Most hermit crabs salvage empty seashells to shelter and protect their soft abdomens. There are about five hundred known species of hermit crabs in the world; although they are mostly aquatic, there are also some terrestrial species. A number of species, most notably king crabs, have abandoned seashells for a free-living life; these species have forms similar to true crabs and are known as carcinized hermit crabs. There are several species of hermit crabs that are common in the marine aquarium trade. These omnivorous or herbivorous species are useful in the household aquarium as scavengers, eating algae and other debris. The scarlet hermit crab, or red reef hermit crab (Paguristes cadenati), is a handsome and interesting species with a bright red body and yellow eyestalks, and stays rather small (about 2-5 cm / 1-2 inches across). Smaller species of a similar passive nature include the zebra hermit crab (brown legs with white bands), the red-tip crab and blue-legged crab.

Ostracods Ostracoda is a class of the Crustacea, sometimes known as the seed shrimp because of their appearance. Some 50,000 extinct and extant species have been identified, grouped into several orders. Ostracods are small crustaceans, typically around one mm in size, but varying between 0.2 to 30 mm, laterally compressed and protected by a bivalve-like, chitinous or calcareous valve or "shell". The hinge of the two valves is in the upper, dorsal region of the body. Ecologically ostracods can be part of the zooplankton, or (most commonly) they are part of the benthos, living on or inside the upper layer of the sea floor. Many ostracods are also found in fresh water and some are known from humid continental forest soils. Our ostracods are freshwater.

Pillbugs Woodlice (known locally under many names; see below) are terrestrial crustaceans with a rigid, segmented, calcareous exoskeleton and fourteen jointed limbs. They form the suborder Oniscidea within the order Isopoda, with over 3000 known species. Woodlice need moisture because they breathe through gills, called pseudotrachea, and so are usually found in damp, dark places, such as under rocks and logs. They are usually nocturnal and are detritivores, feeding mostly on dead plant matter. They should be considered beneficial garden organisms as they recycle nutrients back into the soil. In artificial environments such as greenhouses where it can be very moist, woodlice may become abundant and damage young plants. Common names for woodlice vary throughout the English-speaking world. They include roly-poly, pill bug (usually applied only to the genus Armadillidium), sow bug, doodle bug, carpenter (Newfoundland), woodbug, potato bug, armadillo bug, slater, ball bug, bowling ball bug, chuggy pig, hardy back, butcher boy, daddy gramfer / daddy gampfer (West Country), Granny Grey (South Wales), cheesybug (Kent), and cheeselog.
