Sound Production in the Spiny Lobster Panulirus Argus (Latreille) ,

Acoustic behaviour of the European spiny lobster Palinurus elephas

“…The acoustic signals of spiny lobster species from several areas of the world are known (Moulton 1957, Meyer-Rochow & Penrose 1974, 1976, Patek 2001, Patek & Oakley 2003, Bouwma & Herrnkind 2009). However, little information is available to characterise the rasps emitted by Palinurus elephas.…”

“…Spiny lobsters (Palinuridae), like other arthropods, produce acoustic signals (Moulton 1957, MeyerRochow & Penrose 1974, Patek 2002, Patek & Oakley 2003, Patek & Baio 2007, Bouwma & Herrnkind 2009, Patek et al 2009). The sound is produced by a specialised stridulating organ composed of 2 parts: a movable plectrum attached to the last segment of the antennal peduncle and a rigid file (Meyer-Rochow & Penrose 1974, 1976, Patek 2002, Patek & Oakley 2003, Patek & Baio 2007.…”

“…Friction between the soft underside of the plectrum and the anteriorly projecting scales of the file causes the moving plectrum to alternately stick and slip, producing a pulse of sound with each slip (MeyerRochow & Penrose 1974, 1976, Patek 2001. Some authors have assumed that lobsters only produce sounds in an anti-predator context (Lindberg 1955, Moulton 1957, Hazlett & Winn 1962, Takemura 1971, Meyer-Rochow & Penrose 1974, 1976, Smale 1974, Mulligan & Fischer 1977, Patek 2001, Bouwma & Herrnkind 2009, Patek & Oakley 2003, Patek et al 2009, Staaterman at al 2010. Although various functional hypotheses for distress calls in other animals in anti-predator contexts have been suggested (Smith 1986, Driver & Humphries 1988, Klump & Shalter 1984, the role of lobsters' stridulation and the potential receivers remain unclear.…”

Rapidly obtained ecosystem indicators from coral reef soundscapes

“…Some aspects of the biophony, such as marine mammal calls, are the subject of extensive study (Johnson et al 2009, Richardson et al 2013. However, the majority of acoustic energy in temperate and tropical shallow-water regions is created by a wide variety of other organisms including shrimp (Johnson et al 1947, Au & Banks 1998, lobsters (Moulton 1957, Patek et al 2009), sea urchins (Cummings et al 1964, Radford et al 2008, hermit crabs (Freeman et al 2014), as well as many species of soniferous fishes (Tavolga 1964, Rountree 2008. Ecological processes such as spawning (Tavolga 1964), feeding (Amorim et al 2004), schooling and predator avoidance (Moulton 1960) create acoustic emissions that may contain information regarding the number and size of the organisms present, or the rate of resource consumption in that area.…”

“…As the orientation of organisms, image quality, illumination and occluding material increased uncertainty when identifying organisms to the species level, counts of the photographed organisms were divided into the following, clearly identifiable groups: sea urchins (Echinoida and Cidaroida), crabs (Brachyura), hermit crabs (Paguroidea), brittle stars (Ophiuroidea), starfish (Asteroidea), sea cucumbers (Holothuroidea), fish (Osteichthyes), worms (Annelida and Poly chaeta), eels (Muraenidae) and molluscs (Mollusca). These groups were selected based on the ability of the observers to identify organisms in the photographs, frequency of occurrence, and previous work that linked some of these groups to underwater sounds (Moulton 1957, 1960, Cummings et al 1964, Tavolga 1964, Amorim et al 2004, Radford et al 2008, Patek et al 2009, Freeman et al 2014). An example of typical data from a crepuscular period recorded at Kahekili, Maui, is shown in Fig.…”
