Their goal is to improve bee strains and to increase the honey quality and yield. Apiculture also falls under the category entomology. They analyze environmental conditions that affect these organisms. Thus, ethology mainly concerns instinctive or inherited behavior rather than learned behavior. The ultimate goal of ethologists is to discover how instinctive behavior among related species evolved and now serves to enhance survival.
Herpetologists usually specialize in one or the other of the two classes and often in one organism.
Areas of study include the structure, classification, behavior, development, and distribution of fishes. In addition, ichthyology is concerned with relationships between fishes, the environment, conservation, and humans. The unicellular protozoa are so distinctive that researchers of this group usually regard themselves as protozoologists rather than invertebrate zoologists. Insects are so numerous and economically important that this discipline has developed into a separate field of study, entomology. Professional ornithologists specialize in fields of pure science such as bird anatomy, behavior, ecology, and evolution, or in applied fields such as wildlife management and avian veterinary medicine, and they have a number of societies that publish journals and hold annual meetings.
