Apparently these loose cells reattach to the gut wall after they have “fed.” It has been suggested that upon re- attachment these errant cells first pass their digested food contents to the fixed cells of the gut wall, then assume an excretory function by picking up metabolic wastes, de- taching again and being eliminated via the anus.

Proleg formation appears to involve a change in the regulation and expression of a single gene (abd-A) during embryogenesis. In summary, the processes of microevolution (e.g., natural selection) act on individuals and populations, maintain genomic continuity, and create anastomosing patterns of relationship over time (Figure 1.6) Atlas of Australian Termites download pdf

It is a major mode of feeding in sponges, ascidians, appendicularians, brachiopods, ectoprocts, entoprocts, phoronids, most bivalves, and many crustaceans, polychaetes, and gastropods. The main food selection criterion is particle size, and the size limits of food are determined by the nature of the particle-capturing device. In some cases potential food particles may also be “sorted” on the basis of their spe- cific gravity, or even their perceived nutritional quality download Practical Invertebrate Zoology pdf.

The vast majority of animal species belong to the clade Bilateria, which consists of animals with bilateral symmetry and triploblastic development. The most recent common ancestor of living bilaterians probably lived in the later Proterozoic. During the Cambrian explosion, most major groups of bilaterians emerged.

Their first trunk appendages form large claws, called prehensors or forcipules. These rap- torial limbs are located ventral to the mouth field (Figure 18.2D), and are used to stab prey and inject poison. The poison is produced in large venom glands located in the basal articles of the forcipules. The poison is so effective that large centipedes, such as the tropical Scolopendra, can subdue small vertebrates (e.g., frogs, lizards, snakes, mice, small birds) Pollution Ecology of download pdf

The precise methods of particle detection, iso- lation, and capture vary among different invertebrates that use the scan-and-trap technique; but this basic strat- egy is probably employed by certain crustaceans (e.g., planktonic copepods), many ectoprocts, and a variety of larval forms. 58 CHAPTER THREEUNCORRECTED PAGE PROOFS The trick of removing small food particles from the surrounding environment is achieved through four fun- damentally different mechanisms , e.g. Trends Perspectives read here

Tiny scale insects are commonly collected in aerial nets. In fact, studies have revealed the existence of a large “aerial plankton” of insects and other minute arthropods, extending to altitudes as high as 14,000 feet.

Since the population densities of these pelagic worms are extremely low, they must presumably capitalize on the relatively infrequent encounters of males and females and ensure successful fertilization. In a few cases the males are equipped with suckers, which are used to clasp the female, or, rarely, with a protrusible penis, which is used to transfer sperm , e.g. Advances in the Systematics of download here

Most workers recognize two suborders: Dendrobranchiata and Pleocyemata. This group includes about 450 species of decapods, most of which are penaeid and sergestid shrimps.
