Bolas spiders hunt at night and specialize in feeding on male moths of the genus Spodoptera. When the animal is large, the viscosity is increased by secretion of mucus, which lowers the Reynolds number. These triploblastic coelo- mate worms possess a complete gut, a closed circulatory system, a well devel- oped nervous system, and excretory structures in the form of protonephridia or, more commonly, metanephridia (Box 13A).

A monophyletic group is a group of species that includes an ancestral species and all of its descendants—that is, a natural group (Figure 2.1).

If it’s wrong, it will bounce back, so you will be able to learn the right answers. Our temperature is 98.6 degrees unless we are sick. Cold-blooded animals have a changing body temperature.

CLICK on underlined file names and included illustrations to enlarge: ��������� Invertebrate zoology is a biological discipline that involves the study of invertebrates.� Although vertebrates possess many characters in common with invertebrates they are distinguished by possessing a backbone.� Invertebrates lack a backbone.� Invertebrates comprise over 95 percent of all animal species and certainly more than that percentage in animal biomass.� They have been extensively used in biological researches of heredity, embryology and regeneration.� They also have had great practical importance related to insect damage, the causes of human and animal disease and directly as food, pearls, buttons, etc. ��������� As we proceed to examine the various characteristics of the different animals it becomes obvious that a common bond unites all animals in that we must all respire, consume food, excrete wastes and reproduce. ��������� Zoology may also be divided further into other principal categories such as: Arthropodology = The study of arthropods, including Arachnology (spiders & mites), Entomology (insects) and Carcinology (crustaceans).� Malacology = The study of mollusks.� Invertebrate Paleontology = The study of extinct invertebrates.� For a classification of Invertebrates as treated herein please see Table 1 .� However, the principal groups may also be noted as follows: ��������� The arrangement of the various subgroups is based on ever increasing complexity and presumed evolution of the most primitive [(e.g., Protista (Protozoa)] to the more advanced organisms.� Previous names of groups are included in parentheses.� There continues to be wide disagreement on classification, and although further rearrangements are expected as more biological and biochemical data are forthcoming, the presented design should enable identification of major orders, families and genera
