“…Thus, rather than vibrational period, vibrational frequency might be the important component of the communication. This concurs with findings in landlocked red salmon where the male behavior was clearly influenced by the vibrational frequency of the model female (Satou, Takeuchi, Takei, et al., 1994). Similarly, male and female haddock ( Melanogrammus aeglefinus ) seem to synchronize reproductive behavior by sound from muscle vibrations as well (Hawkins & Amorim, 2000).…”

A mismatch in synchrony between male and female gamete release in external fertilizers can result in reduced or failed fertilization, sperm competition, and reduced paternity. In Arctic charr (Salvelinus alpinus), males can adopt either a guard or sneak tactic resulting in both pre‐ and postcopulatory competition between males with alternative reproduction tactics. Here, spawning behavior of free‐living Arctic charr was video‐recorded, and their reproductive behavior was analyzed. From evaluating 157 spawning events, we observed that females mainly spawned with a guarding male and that the female and the guarding male synchronized timing of gamete release under sperm competition. Although sneakers spawned with higher synchrony than the guarding male in single‐male spawning events, the average sneaker released his milt less synchronized with the female than the guarding male under sperm competition. Approximately 50% of the recorded spawning events occurred under sperm competition, where each event included an average of 2.7 males. Additionally, sneakers were more exposed to sperm competition than guarding males. An influx of males, in close proximity to the female, occurred during the behavioral sequences leading up to egg release, but this influx seemed not dependent on egg release, suggesting that something else than gonadal product attracts sneaker males to the spawning female. Just before and during the actual release of gametes, the spawning couple vibrates their bodies in close contact and it seems likely that this vibrational communication between the spawning couple, which results in a larger amplitude sound wave than seen under regular courting, reveals time of gamete release to sneaker males. Thus, vibrational communication may enable synchrony between the guarding male and the female, and this might be traded against the cost of higher detectability from surrounding sneaker males, eavesdropping in close proximity.

“…However, visual displays in fish are often complemented by acoustic stimuli that can improve information transfer or reduce signal ambiguity. For example, in some species a sound or mechanical stimulus produced during visual stimulation by males is necessary to evoke female courtship (Tavolga, 1956;Myrberg et al, 1986;Ladich, 1990;Lobel, 1992;Mann and Lobel, 1998), enhance territory defense (Myrberg, 1997) and spawning (Satou, 1994a;Satou, 1994b). Thus, it is often necessary to understand the stimuli and functions of multiple sensory systems to interpret the evolution of behavioral displays and social interactions.…”

SUMMARY Butterflyfishes are conspicuous members of coral reefs and well known for their visual displays during social interactions. Members of the genus Chaetodon have a unique peripheral arrangement of the anterior swim bladder that connects with the lateral line (the laterophysic connection) and in many species projects towards the inner ear. This morphology has lead to the proposal that the laterophysic connection and swim bladder system may be a specialized structure for the detection of sound. However, the relevant stimuli, receiver mechanisms and functions for these putative hearing structures were unknown because butterflyfishes were previously not recognized to produce sounds during natural behavior. We performed field experiments to test the hypothesis that Chaetodon produces sounds in natural social contexts. Acoustic and motor behaviors of the monogamous multiband butterflyfish, C. multicinctus, were evoked and recorded by placement of bottled fish into feeding territories of conspecific pairs. We demonstrate that territory defense includes the production of agonistic sounds and hydrodynamic stimuli that are associated with tail slap, jump, pelvic fin flick and dorsal-anal fin erection behaviors. In addition, grunt pulse trains were produced by bottled intruders and are tentatively interpreted to function as an alert call among pair mates. Acoustic behaviors include low frequency hydrodynamic pulses <100 Hz, sounds with peak energy from 100 Hz to 500 Hz,and a broadband high frequency click (peak frequency=3.6 kHz), which is produced only during the tail slap behavior. These results provide a biological framework for future studies to interpret the proximate function of the acoustico-lateralis sensory system, the evolution of the laterophysic mechanism and their relevance to butterflyfish social behavior.

“…It is has long been thought that multiple submodalities are important in guiding complex behaviors, such as orienting to prey in a current, detecting and localizing vibratory sources for predatory and communicatory behaviors, and wake tracking. This has been addressed in a number of recent studies [Satou et al, 1994;Liang et al, 1998;Sargent et al, 1998;Pohlmann et al, 2001]. Technically, although stimuli are complex and their generation is challenging, the systems are individually accessible, much more so than in comparison with mammalian cutaneous sensors, for instance.…”

The octavolateralis system consists of several submodalities, including the inertial-sensitive inner ear, the pressure-sensitive ear/air cavity complex (when present), and acceleration- and velocity-sensitive components of the lateral line system (canal and superficial neuromasts, respectively). All four of these channels are responsive to many of the same stimulus sources, particularly moving or vibrating objects within a short distance from the receiver. We therefore argue that the octavolateralis system is an excellent model for the study of multisensory interactions. We focus on the possible ways in which these channels may contribute to source localization mechanisms and to the multisensory guidance of behaviors with strong directional components (e.g., predator avoidance, prey capture and mate attraction). Finally, we define four ways in which information from multiple senses might interact. These include fractionation, synergy, accessory stimulation, and complementation. Although evidence for all types of octavolateralis interactions can be found, the primary modes of interaction appear to be complementation and fractionation. For example, the inertial and pressure-sensitive submodalities of the auditory system provide complementary pieces of information about the direction (e.g., left/right) and polarity (advancing or receding) of a moving source. In contrast, the lateral line canal system subserves short-range localization tasks, whereas the auditory system may subserve longer-range detection and localization tasks.
