Booklice Booklice, also called psocids, are not true lice. While they resemble lice in size and shape, booklice feed only on fungi or mold. If you find them in grain or other stored food products, it is an indication of high humidity which encourages mold growth.hile their back legs are thicker than the other four, and resemble the legs found in jumping insects, booklice do not jump, but run about rather quickly. Adult booklice range in color from translucent white to gray or brown.

- 1 Subclass Pulmonata. Order STYLOMMATOPHORA. Suborder Sigmurethra. The families: Testacellidae. These are an earthworm's enemy, a carnivore with sharp teeth that impale their wormy prey. The remnant of a shell at the tail end of the slug covers the mantle and organs. This family is comprised of a single genus, Testacella. Testacella has been introduced into North America and New Zealand. Regionally, Testacella sp. has been found in the Portland and Eugene areas of Oregon.

Arthropoda - Crustaceans, Insects This phylum includes insects like butterflies and beetles, crustaceans like crabs and lobsters, and chelicerates like spiders and scorpions. Arthropods are found in all parts of the world in a wide variety of environments, from the deep sea to the frozen arctic regions.ost arthropod's bodies have three sections-the head, the thorax, and the abdomen. The thorax is the part of the body between the head and the abdomen. In some species of arthropods, the head and the thorax are one section called the cephalothorax.

- Klebsormidium (Figure D) is an unbranched filament of the Klebshormidiophyceae. It was once considered to be a relative of Ulothrix (in the Chlorophyta), but it is now known that the resemblance (unbranched filaments with parietal plate chloroplasts) is only superficial.oleochaetae (Figure H; in the Coleochaetophyceae) is an attached flat plate of cells that grows as an appressed, branched network. They form upright oogonia sheathed by sterile cells and spermatozoids formed in antheridia.

Daphnia Daphnia, a genus of small planktonic crustaceans, are 1–5 millimetres (0.04–0.20 in) in length. Daphnia are members of the order Cladocera, and are one of the several small aquatic crustaceans commonly called water fleas because their saltatory [1] swimming style resembles the movements of fleas.he two most readily available species of Daphnia are D. pulex (small and most common) and D. magna (large). They are often associated with a related genus in the order Cladocera: Moina, which is in the Moinidae family instead of Daphniidae and is much smaller than D. pulex (approximately half the maximum length).

Zooplankton The Polychaeta or polychaetes are a paraphyletic class of annelid worms, generally marine. Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin. Indeed, polychaetes are sometimes referred to as bristle worms.

Annelid Annelids are considered members of the Lophotrochozoa, a super-phylum of protostomes that also includes molluscs, brachiopods, flatworms and nemerteans. The basic annelid form consists of multiple segments. Each segment has the same sets of organs and, in most polychates, has a pair of parapodia that many species use for locomotion. Septa separate the segments of many species, but are poorly defined or absent in others, and Echiura and Sipuncula show no obvious signs of segmentation.
