While eye sensitivity in the American horseshoe crab Limulus polyphemus has long been known to be under the controlof an endogenous circadian clock, only recently has horseshoe crab locomotion been shown to be controlled by a separateclock system. In the laboratory, this system drives clear activity rhythms throughout much of the year, not just during the matingseason when horseshoe crabs express clear tidal rhythms in the field. Water temperature is a key factor influencing the expressionof these rhythms: at 17℃ tidal rhythms are expressed by most animals, while at 11℃ expression of circatidal rhythms is rarelyseen, and at 4℃ rhythms are suppressed. Neither long (16:8 Light:Dark) nor short (8:16) photoperiods modify this behavior atany of these temperatures. Synchronization of these circatidal rhythms can be most readily effected by water pressure cycles bothin situ and in the lab, while temperature and current cycles play lesser, but possibly contributory, roles. Interestingly, Light:Darkcycles appear to have synchronizing as well as 'masking' effects in some individuals. Evidence that each of two daily bouts ofactivity are independent suggests that the Limulus circatidal rhythm of locomotion is driven by two (circalunidian) clocks, eachwith a period of 24.8h. While the anatomical locations of either the circadian clock, that drives fluctuations in visual sensitivity, orthe circatidal clock, that controls tidal rhythms of locomotion, are currently unknown, preliminary molecular analyses have shownthat a 71 kD protein that reacts with antibodies directed against the Drosophila PERIOD (PER) protein is found in both the protocerebrumand the subesophageal

The use of multisensory cues to locate mates can increase an organism's success by acting as a back-up plan whenone system fails, by providing additional information to the receiver, and by increasing their ability to detect mates using sensesthat have different ranges in a variable aquatic environment. In this contribution we review the sensory cues that male horseshoecrabs Limulus polyphemus are known to use when locating mates and then provide new data that shed light on this subject. Duringthe breeding season, females migrate into shore during high tides to spawn. Males attach to females as they approach thebeach or are attracted to pairs already spawning. Vision is well established as an important cue in attracting males. Althoughchemoreception is well known in other marine arthropods, and horseshoe crabs have the anatomy available, there are few studieson chemical cues in this species. Experiments are presented here that provide evidence for chemical cue use. We show that the attraction,and retention, of attached and satellite males to actively spawning females and mating pairs involves multimodal
