“…during migration (Herrnkind 1969, Herrnkind et al 1973, Lipcius & Herrnkind 1985, Herrnkind et al 2001, Lavalli & Herrnkind 2009 or as an anti-predator tactic (Herrnkind et al 2001, Nishimura 2002, Briones-Fourzán et al 2006, Lavalli & Herrnkind 2009), could suggest that these animals use acoustic signals in addition to the chemical signals that spread slowly and for short distances (Nevitt et al 2000, Briones-Fourzán 2009. Acoustic signals may allow lobsters to maintain contact with conspecifics and to use clustering and aggregation as anti-predator tactics (Herrnkind et al 2001, Barshaw et al 2003, Briones-Fourzán et al 2006, Lavalli & Herrnkind 2009). …”

The acoustic behaviour of the European spiny lobster Palinurus elephas (Fabricius, 1787) was examined in the absence or presence of predators or conspecifics. Observations were conducted in a tank equipped with digital video and acoustic monitoring and recording systems using 25 adult lobsters and 5 common octopuses Octopus vulgaris. Single lobsters or groups of 4 lobsters were studied for 2 h. These were left alone during the first hour and exposed to a single specimen of the common octopus during the second hour. The lobsters' signals were acoustically analysed. Signal duration, number of pulses per signal, pulse rate, bandwidth, peak intensity, and peak frequency were measured. Single lobsters emitted a higher number of signals than lobsters belonging to a group. The signal (rasp) was audible to humans only in the presence of a predator and was always associated with specific behavioural events. In the absence of a predator, the lobsters produced ultrasound signals (screech) having lower duration, number of pulses per signal, bandwidth, and peak intensity and higher pulse rate and peak frequency. Audible rasps were produced in an anti-predator context, whereas the ultrasound screeches were also emitted under non-stressful conditions. Thus, these signals may play a role in intraspecific communication.

“…Clawed lobsters are often aggressive (Scrivener 1971), and form dominance hierarchies (Karnofsky & Price 1989, Atema & Voight 1995. In clawless lobsters, defensive structures are limited to their robust antenna and armoured carapace (Atema & Cobb 1980, Barshaw et al 2003, and they are often associated with conspecifics (Herrnkind 1969).…”

Ecological role of large benthic decapods in marine ecosystems: a review

Large benthic decapods play an increasingly important role in commercial fisheries worldwide, yet their roles in the marine ecosystem are less well understood. A synthesis of existing evidence for 4 infraorders of large benthic marine decapods, Brachyura (true crabs), Anomura (king crabs), Astacidea (clawed lobsters) and Achelata (clawless lobsters), is presented here to gain insight into their ecological roles and possible ecosystem effects of decapod fisheries. The reviewed species are prey items for a wide range of invertebrates and vertebrates. They are omnivorous but prefer molluscs and crustaceans as prey. Experimental studies have shown that decapods influence the structuring of benthic habitat, occasionally playing a keystone role by suppressing herbivores or space competitors. Indirectly, via trophic cascades, they can contribute to the maintenance of kelp forest, marsh grass, and algal turf habitats. Changes in the abundance of their predators can strongly affect decapod population trends. Commonly documented nonconsumptive interactions include interference-competition for food or shelter, as well as habitat provision for other invertebrates. Anthropogenic factors such as exploitation, the creation of protected areas, and species introductions influence these ecosystem roles by decreasing or increasing decapod densities, often with measurable effects on prey communities. Many studies have investigated particular ecosystem effects of decapods, but few species were comprehensively studied in an ecosystem context. A simplified synthetic framework for interpreting eco system roles of decapods was derived from the available evidence; however, more experimental and long-term observational studies are needed to elucidate mechanisms and shed light on the longterm consequences of decapod fisheries.

“…Consideration should be given to H. gammarus olfaction, where current processes govern the transportation and therefore concentration of scent cues in the water column, which may influence an individual's behaviour and therefore choice of movement direction (Skog 2009;Barshaw et al 2003). As release sites varied across the study area up to 12 nautical miles offshore, the geographical constraints of the coastline did not appear to impact H. gammarus' ability to move in a westerly direction inshore.…”
