“…We found a higher prevalence of parasitism in females, but previous studies of lithodids have reported conflicting results on the subject of gender bias (Watters 1998;Poltev 2008). The prevalence of parasites may vary by location (Otto and MacIntosh 1996;Lovrich et al 2004); compared with the 14% of P. birsteini infected by B. callosus in the present study, rates of parasitism ranging from \1% to as high as 75% have been reported for lithodid populations globally (Hawkes et al 1985;Hoggarth 1990;Watters 1998;Anosov et al 2014). Consequently, the prevalence could be different in other P. birsteini populations.…”

Biology of the king crab Paralomis birsteini on the continental slope off the western Antarctic Peninsula

et al. 2017

Predatory king crabs (Lithodidae) structure benthic communities in their native habitats and cause shifts in the composition of benthic assemblages when introduced to new environments. Cold temperatures have apparently excluded skeleton-breaking predators from the continental shelf around Antarctica for millions of years, but recent increases in sea temperatures off the western Antarctic Peninsula (WAP) may be allowing lithodids to return. Imaging surveys have revealed dense populations of the lithodid Paralomis birsteini (Macpherson 1988) living on the continental slope off the WAP, but the biology of these populations remains poorly understood. We collected 51 adult P. birsteini in a trapping study on the slope off Marguerite Bay, WAP from depths of 1200-1400 m. Of the 51 crabs, 42 were males and 9 were females. Four females were ovigerous, carrying eggs at various stages of development. Rates of parasitism and limb regeneration were comparable to populations of lithodids elsewhere in the world, although the proportion of limb loss was relatively high. Externa of the parasite Briarosaccus callosus was obvious in both males and females, with one individual bearing hyperparasites (probably Liriopsis pygmaea). Gill necrosis was also observed in several dissected males. The success of contemporary lithodid populations on the Antarctic slope suggests they have the potential to expand upward to the continental shelf.

“…Crab trapping is also often biased toward larger males, which enter the traps more readily (Miller 1990). Similarly disproportionate sex ratios have been reported for multiple species of lithodids collected using a comparable trapping technique in the deep sea off the South Orkney Islands and in the northern Scotia Sea (Anosov et al 2014).…”

“…Species of king crabs (Lithodidae) may reach the deep sea (Hall & Thatje, 2009), and it is conceivable that the introduced red king crab, a stenobar in its realised habitat, is a physiological eurybar capable of exploring greater depths. As a noteworthy analogue, king crabs of the Southern Ocean now reoccur in the warming waters on the Antarctic Shelf (1-2°C) after they allegedly disappeared from the region during the cooling period some 15 Ma (Thatje et al, 2005;Hall & Thatje, 2011;Smith et al, 2012;Anosov et al, 2015).…”

Aim A focal task for invasion biology is to identify the environmental variables and biological traits that set and underpin realised and potential habitats of invasive species. Ecophysiology provides powerful empirical knowledge that connects theory with natural phenomena and may improve the accuracy of species distribution modelling. We used the introduced Kamchatka red king crab Paralithodes camtschaticus of the Barents Sea as a prime case to show how thermal behaviour may drive the spreading of a marine invader in context of ocean warming. Finally, we discuss the conceivable consequences for a poleward spread of invasive top predators on native marine biota, conservation and management policies.Location Barents Sea, Euro-Arctic shelves, Northeast Atlantic. Methods We used novel and non-manipulative tests which allowed adult red king crab to freely select and monitor ambient temperature in situ across a < 1-14°C gradient by means of a temperature data storage tag attached to the carapace.Results Adult red king crab, irrespective of body size, maturation stage and nutritional state, (1) displays clear behavioural thermoregulation in a heterothermal environment and, (2) conclusively selects temperatures in the coldest end of a gradient and avoids temperatures > 4°C. The final thermal preferendum matches completely present day Arctic shelf temperatures north and east in the Barents Sea.Main conclusions This is the first published study on the thermal behaviour of a marine invasive top predator. Our tests and the concurrent realised habitat north-east of Kola Peninsula suggest that the introduced red king crab is capable of invading the Euro-Arctic shelves in less than three decades. We argue that current management practices of the introduced red king crab compromise Arctic biodiversity and conservation and, to counteract further spreading, we recommend free fisheries on this species across its entire distributional area in the Northeast Atlantic.

“…L. murrayi shares a morphological affinity with Lithodes species from the North-west Pacific and Indian Oceans ( L. longispina , Macpherson and Chan 2008 , L. richeri ), rather than with those from the North East Pacific or Atlantic ( L. aequispinus , L. santolla , Macpherson 1988 ). L. murrayi is, however, currently considered to have a wide distribution around the Southern Ocean: reported from Crozet (as sampled here), as well as the Bellingshausen Sea; however, it is not known from New Zealand and Australia (see Garcia-Raso et al 2005 ; Ahyong 2010 ; Anosov et al 2015 ), and morphological similarities are strong with L. turkayi from the Scotia Sea. L. ferox is found along the western coast off Africa, and shares a number of morphological features with L. murrayi .…”

The objectives of this work are to use gene sequence data to assess the hypothesis that the Lithodinae arose from ancestors with uncalcified abdomens in shallow waters of the North-East Pacific, investigate the monophyly and interrelationships of genera within the Lithodinae and to estimate the scale and minimum number of biogeographic transitions from the shallow environment to the deep sea and vice versa. To do this, phylogenetic analysis from three mitochondrial and three nuclear markers was conducted using minimum evolution, maximum likelihood and Bayesian methods. The Lithodinae as defined to include North Pacific genus Cryptolithodes may be paraphyletic, with the Hapalogastrinae and Cryptolithodes as sister taxa. This implies that the soft-bodied abdomen of the Hapalogastrinae might not be plesiomorphic for the Lithodidae. Paralomis, Lopholithodes, Phyllolithodes, Lithodes and Neolithodes share a common ancestor, from which the North Pacific Hapalogastrinae did not descend. Lithodid ancestors are likely to have had a north Pacific, shallow water distribution and to have had planktotrophic larvae. North Pacific genus Paralithodes is paraphyletic; P. brevipes is the most basal member of the genus (as sampled) while P. camtschaticus and P. platypus are more closely related to the genera Lithodes and Neolithodes. Genera Lithodes, Neolithodes and Paralomis (as sampled) are monophyletic if Glyptolithodes is included within Paralomis. Lopholithodes is closely related to, but not included within, the Paralomis genus. Paralomis is divided into at least two major lineages: one containing South Atlantic, West African, and Indian Ocean species, and the other containing Pacific and South American species. Several species of Paralomis do not resolve consistently with any other groups sampled, implying a complex and possibly rapid global evolution early in the history of the genus. Relationships within the Lithodes genus vary between analytical methods, suggesting that conclusions may not be stable. Consistently, however, Indian Ocean and Pacific forms—L. murrayi, L. longispina and L. nintokuae form a group separated from Atlantic species such as L. santolla, L. confundens, L. maja and L. ferox.Electronic supplementary materialThe online version of this article (10.1007/s00114-018-1544-2) contains supplementary material, which is available to authorized users.
