Discusses the anatomy and physiology of the horseshoe crab (Limulus polyphemus). Includes comments on the habitat of and research studies using this organism. (JN)

Discusses mechanisms and functional intent of visual communication signals in iguanid/agamid lizards. Demonstrated that lizards communicate with each other by using pushups and head nods and that each species does this in its own way, conveying different types of information. (JN)

Basic marine aquaria equipment, techniques for maintenance, specimens and food for the marine organisms are discussed. Several sources of specimens are included. (SA)

Describes a study using two genera of aquatic insects that demonstrates how nonlethal falls in oxygen concentration affect the rate of surfacing of bottom-feeding Coroxidae and how this affects their survival by increasing their proneness to attacks by surface-feeding Notonectidae. (CS)
