“…(See Fig. 3B for typical crabs, with ∼2.7 cm carapace length; carapace length as measured by Gómez-Gutiérrez et al, 2000 ). For most of the footage, the submarine hovered 2–3 m above the bottom, and the submarine and its lights did not appear to affect the behavior of the crabs.…”

“…Large individuals reproduce, but observations of pelagic ovigerous females and their larvae in waters over bathyal and abyssal depths (∼2,000–3,500 m) suggests that a fraction of the pelagic population can reproduce as well ( Longhurst & Seibert, 1971 ). Pleuroncodes planipes can be extremely abundant, with accounts of dense pelagic patches up to 7–10 km ( Gómez-Gutiérrez et al, 2000 ). See also the casual account of a 16 km patch by B. Shimada, quoted in Boyd (1967) .…”

“…The southernmost geographic end range of P. planipes appears to be somewhere in Costa Rica ( Wicksten, 2012 ), where it is thought to overlap with the northern range of Pleuroncodes monodon ( Macpherson et al, 2010 ; Wehrtmann et al, 2010 ; Wicksten, 2012 ). The center of abundance of pelagic P. planipes is in western Baja California ( Longhurst, 1968 ; Brinton, 1979 ; Gómez-Gutiérrez et al, 2000 ). The distribution and abundance of benthic P. planipes is not well documented, particularly south of Baja California.…”

A research cruise to Hannibal Bank, a seamount and an ecological hotspot in the coastal eastern tropical Pacific Ocean off Panama, explored the zonation, biodiversity, and the ecological processes that contribute to the seamount’s elevated biomass. Here we describe the spatial structure of a benthic anomuran red crab population, using submarine video and autonomous underwater vehicle (AUV) photographs. High density aggregations and a swarm of red crabs were associated with a dense turbid layer 4–10 m above the bottom. The high density aggregations were constrained to 355–385 m water depth over the Northwest flank of the seamount, although the crabs also occurred at lower densities in shallower waters (∼280 m) and in another location of the seamount. The crab aggregations occurred in hypoxic water, with oxygen levels of 0.04 ml/l. Barcoding of Hannibal red crabs, and pelagic red crabs sampled in a mass stranding event in 2015 at a beach in San Diego, California, USA, revealed that the Panamanian and the Californian crabs are likely the same species, Pleuroncodes planipes, and these findings represent an extension of the southern endrange of this species. Measurements along a 1.6 km transect revealed three high density aggregations, with the highest density up to 78 crabs/m2, and that the crabs were patchily distributed. Crab density peaked in the middle of the patch, a density structure similar to that of swarming insects.

“…The pelagic distribution of munidids has been related to areas of relatively high primary productivity, for example, in the shelf break and/or areas of active upwelling off Mexico and Perú (Gómez- Gutiérrez et al 2000;Gutiérrez et al 2008). Massive occurrence of P. planipes can only be sustained in areas where food is abundant .…”

“…Off Baja California, Mexico, P. planipes spends its first year of life in the water column and is considered one of the most abundant species of the plankton/micronekton (AuriolesGamboa et al 1994). This species can be found in massive concentrations near the surface, or forming swarms several kilometers long in midwater, during spring, as detected by echosounding (Robinson and Gómez-Gutiérrez 1998;Gómez-Gutiérrez et al 2000). Off the Pacific coast of South America, in the southern (30-37°S) and northern (5-14°S) limit of its distribution, juveniles and adults of P. monodon are both benthic or micronektonic (Gallardo et al 1994;Roa et al 1995;Gutiérrez et al 2008).…”

Pelagic swarms and beach strandings of the squat lobster Munida gregaria (Anomura: Munididae) in the Beagle Channel, Tierra del Fuego

The present article is the first formal record of pelagic swarms and beach strandings of the squat lobster Munida gregaria in the Beagle Channel, southern South America. To describe size composition and natural diet of beach strandings and swarms, samples from strandings were taken surveys were carried out to describe both, horizontal distribution and school metrics of swarms. Pelagic swarms and beach strandings were composed of 100% individuals of the morph gregaria of M. gregaria. Mean size of males and females in both, beach strandings and swarms, were similar. The diet of pelagic M. gregaria was composed mainly of crustaceans, unicellular algae and small macroalgae, sediment and particulate organic matter. Swarms of pelagic Munida took the shape of extended layers of varying density and height. Their positions in the water column were also variable: swarms were found at different depths, from the subsurface layer to near the sea bottom. Occasionally, some large swarms occupied most of the water column. In the Beagle Channel, SW winds during spring tides could be a forcing factor for M. gregaria strandings. The absence of shoaling animals in the Beagle Channel between 1997 and 2002 and the recent occurrence of swarms are coincident with their appearance in other locations in Patagonia. In consequence, we hypothesize that the factor influencing the formation of swarms must be acting at a regional scale.

Anomalous poleward advection facilitates episodic range expansions of pelagic red crabs in the eastern North Pacific

The episodic stranding of millions of pelagic red crabs (Pleuroncodes planipes) along California beaches is a striking and puzzling phenomenon. Pleuroncodes planipes are usually abundant off Baja California, Mexico, and their appearance in central California is thought to coincide with anomalously warm waters and northward advection related to El Niño. This anecdotal association has stimulated many hypotheses, but no hypothesis has gained clear and convincing support. Motivated by an unprecedented number of P. planipes strandings and at-sea observations in 2015-2019, we compiled 10 P. planipes datasets spanning 1950-2019, tested the anomalous advection hypothesis using a transport analysis from 1981 to 2010, and explored other compelling hypotheses. We found P. planipes presence off central California was related to anomalous advection of waters from Mexico, sometimes but not always associated with El Niño events, with P. planipes likely remaining residents of northern waters for several years without additional anomalous transport but potentially facilitated by warm waters. By identifying a mechanism behind episodic P. planipes range expansions, we show that a source water index could provide an early indicator for anomalous events in the future.
