A Massive Record of the Rare 'Mole Crab' Albunea Carabus (Decapoda BULLETIN OF THE ENTOMOLOGICAL SOCIETY OF MALTA (2017) Vol. 9 43 4th International Congress on Biodiversity “Man, Natural Habitats and Euro-Mediterranean Biodiversity”, Malta, 17-19th November 2017 A massive record of the rare ‘mole crab’ Albunea carabus (Decapoda: Anomura: Hippoidea) along the sandy coasts of Catania Danilo SCUDERI1*, Alberto VILLARI2 & Massimiliano ANGELICO2 Amongst the Crustacea, the Decapoda (which include crayfish, crabs, lobsters, prawns, and shrimp) represent a highly diverse group adapted to many different marine and freshwater environments. Members of the Superfamily Hippoidea are commonly referred to as mole crabs. This group includes three families of which one, Albuneidae, is represented in the Mediterranean basin by only one species, the mole crab, Albunea carabus (Linnaeus, 1758). This species prefers sandy bottoms, where it borrows in littoral sites exposed to high hydrodynamic processes. Along the Mediterranean coasts and Atlantic Ocean, it appears to be a well-established and distributed species, even if its findings have always been based on very few specimens from single localities. The only exception was a rare case in the Atlantic, where a number of massive findings were reported. During the Winter of 2017, thousands of specimens of this ‘mole crab’ were found beached, mostly still alive, along the sandy coasts of Catania (eastern Sicily). Marine birds, and stray dogs preyed on them. This environment is characterised by a homogeneous bottom of fine sand, and freshwater affluxes come from numerous rivers and torrents with strong water currents in certain places. Based on this beaching of Albunea carabus, this communication reports the first massive record of this species in the Mediterranean. 1 IISS “E. Majorana”, via L.

GONZÁLEZ University of Las Palmas de Gran Canaria, i-UNAT, Campus de Tafira, 35017 Las Palmas de Gran Canaria, Spain. E-mail: [email protected]. ORCID iD: 0000-0001-8584-6731. Abstract The complete list of Canarian marine decapods (last update by González & Quiles 2003, popular book) currently com- prises 374 species/subspecies, grouped in 198 genera and 82 families; whereas the Cape Verdean marine decapods (now fully listed for the first time) are represented by 343 species/subspecies with 201 genera and 80 families. Due to changing environmental conditions, in the last decades many subtropical/tropical taxa have reached the coasts of the Canary Islands. Comparing the carcinofaunal composition and their biogeographic components between the Canary and Cape Verde ar- chipelagos would aid in: validating the appropriateness in separating both archipelagos into different ecoregions (Spalding et al. 2007), and understanding faunal movements between areas of benthic habitat. The consistency of both ecoregions is here compared and validated by assembling their decapod crustacean checklists, analysing their taxa composition, gath- ering their bathymetric data, and comparing their biogeographic patterns. Four main evidences (i.e. different taxa; diver- gent taxa composition; different composition of biogeographic patterns; different endemicity rates) support that separation, especially in coastal benthic decapods; and these parametres combined would be used as a valuable tool at comparing biotas from oceanic archipelagos.

  • Nansei Islands Biological Diversity Evaluation Project Report 1 Chapter 1
    Introduction WWF Japan’s involvement with the Nansei Islands can be traced back to a request in 1982 by Prince Phillip, Duke of Edinburgh. The “World Conservation Strategy”, which was drafted at the time through a collaborative effort by the WWF’s network, the International Union for Conservation of Nature (IUCN), and the United Nations Environment Programme (UNEP), posed the notion that the problems affecting environments were problems that had global implications. Furthermore, the findings presented offered information on precious environments extant throughout the globe and where they were distributed, thereby providing an impetus for people to think about issues relevant to humankind’s harmonious existence with the rest of nature. One of the precious natural environments for Japan given in the “World Conservation Strategy” was the Nansei Islands. The Duke of Edinburgh, who was the President of the WWF at the time (now President Emeritus), naturally sought to promote acts of conservation by those who could see them through most effectively, i.e. pertinent conservation parties in the area, a mandate which naturally fell on the shoulders of WWF Japan with regard to nature conservation activities concerning the Nansei Islands. This marked the beginning of the Nansei Islands initiative of WWF Japan, and ever since, WWF Japan has not only consistently performed globally-relevant environmental studies of particular areas within the Nansei Islands during the 1980’s and 1990’s, but has put pressure on the national and local governments to use the findings of those studies in public policy. Unfortunately, like many other places throughout the world, the deterioration of the natural environments in the Nansei Islands has yet to stop.

  • Concluding Remarks
    Concluding Remarks The bulk of secretory material necessary for the encapsulation of spermatozoa into a spermatophore is commonly derived from the male accessory organs of re­ production. Not surprisingly, the extraordinary diversity in size, shape, and struc­ ture of the spermatophores in different phyla is frequently a reflection of the equally spectacular variations in the anatomy and secretory performance of male reproductive tracts. Less obvious are the reasons why even within a given class or order of animals, only some species employ spermatophores, while others de­ pend on liquid semen as the vehicle for spermatozoa. The most plausible expla­ nation is that the development of methods for sperm transfer must have been in­ fluenced by the environment in which the animals breed, and that adaptation to habitat, rather than phylogeny, has played a decisive role. Reproduction in the giant octopus of the North Pacific, on which our attention has been focussed, pro­ vides an interesting example. During copulation in seawater, which may last 2 h, the sperm mass has to be pushed over the distance of 1 m separating the male and female genital orifices. The metre-long tubular spermatophore inside which the spermatozoa are conveyed offers an obvious advantage over liquid semen, which could hardly be hauled over such a long distance. Apart from acting as a convenient transport vehicle, the spermatophore serves other purposes. Its gustatory and aphrodisiac attributes, the provision of an ef­ fective barrier to reinsemination, and stimulation of oogenesis and oviposition are all of great importance. Absolutely essential is its function as storage organ for spermatozoa, at least as effective as that of the epididymis for mammalian spermatozoa.

ABSTRACT: The key deals with the Decapoda, Anomura of the northern Arabian Sea, belonging to 3 superfamilies, 10 families, 32 genera and 104 species. With few exceptions, each species is accompanied by illustrations of taxonomic importance; its first reporter is referenced, supplemented by a subsequent record from the area. Necessary schematic diagrams explaining terminologies are also included. KEY WORDS: Malacostraca, Decapoda, Anomura, Arabian Sea - key. INTRODUCTION The Infraorder Anomura is well represented in Northern Arabian Sea (Paldstan) (see Tirmizi and Kazmi, 1993). Some important investigations and documentations on the diversity of anomurans belonging to families Hippidae, Albuneidae, Lithodidae, Coenobitidae, Paguridae, Parapaguridae, Diogenidae, Porcellanidae, Chirostylidae and Galatheidae are as follows: Alcock, 1905; Henderson, 1893; Miyake, 1953, 1978; Tirmizi, 1964, 1966; Lewinsohn, 1969; Mustaquim, 1972; Haig, 1966, 1974; Tirmizi and Siddiqui, 1981, 1982; Tirmizi, et al., 1982, 1989; Hogarth, 1988; Tirmizi and Javed, 1993; and Siddiqui and Kazmi, 2003, however these informations are scattered and fragmentary. In 1983 McLaughlin suppressed the old superfamily Coenobitoidea and combined it with the superfamily Paguroidea and placed all hermit crab families under the superfamily Paguroidea.

GOTTLIEB 93 Material of this species was examined from the following localities: Haifa Bay (samples 98, 245), Atlit, Tantura, Caesarea (rock pools, VI. 1946) and Bat Yam. The Haifa specimens were collected at depths of 22 and 29 m, respectively. The carapace lengths of the specimens varied between 4.5 and 23 mm; in two ovigerous females it was 11 and 11.5 mm, respectively. Xantho poressa is also known under the names Xantho hydrophilus (Herbst 1790) and Xantho rivulosus (Risso 1816), both of which are incorrect (see Hol- thuis 1954). The systematics of this and related species of the genus have been dealt with extensively by Drach and Forest (1953). The species inhabits the entire Mediterranean, the Black Sea and the Canary Islands. The records from the E Mediterranean are : Navarino Bay, Methone (=Modon) and Sapientza, S Greece (Guerin 1832, as Cancer cinereus), Phale- ron Bay near Athens (Athanassopoulos 1917), Bosporus (Heller 1863), Istanbul fishmarket (Ninni 1923), near Gallipoli, Sea of Marmara (OstroumorT 1896), near Khania, NW Crete (Lucas 1853, Raulin 1870), Rhodes (Santucci 1928, Tortonese 1947), Cyprus (Heller 1863), Lebanon (Drach and Forest 1953), Sidon ( =Saida), Lebanon (Monod 1931), Israel (Bodenheimer 1935, 1937), Haifa (Steinitz 1933), Caesarea, Israel (Gottlieb 1953), Egypt (Audouin 1826), Port Said (Caiman 1927), near Alexandria, Egypt (Balss 1936).
