Learning in Stomatopod Crustaceans
International Journal of Comparative Psychology, 2006, 19 , 297-317. Copyright 2006 by the International Society for Comparative Psychology Learning in Stomatopod Crustaceans Thomas W. Cronin University of Maryland Baltimore County, U.S.A. Roy L. Caldwell University of California, Berkeley, U.S.A. Justin Marshall University of Queensland, Australia The stomatopod crustaceans, or mantis shrimps, are marine predators that stalk or ambush prey and that have complex intraspecific communication behavior. Their active lifestyles, means of predation, and intricate displays all require unusual flexibility in interacting with the world around them, imply- ing a well-developed ability to learn. Stomatopods have highly evolved sensory systems, including some of the most specialized visual systems known for any animal group. Some species have been demonstrated to learn how to recognize and use novel, artificial burrows, while others are known to learn how to identify novel prey species and handle them for effective predation. Stomatopods learn the identities of individual competitors and mates, using both chemical and visual cues. Furthermore, stomatopods can be trained for psychophysical examination of their sensory abilities, including dem- onstration of color and polarization vision. These flexible and intelligent invertebrates continue to be attractive subjects for basic research on learning in animals with relatively simple nervous systems. Among the most captivating of all arthropods are the stomatopod crusta- ceans, or mantis shrimps. These marine creatures, unfamiliar to most biologists, are abundant members of shallow marine ecosystems, where they are often the dominant invertebrate predators. Their common name refers to their method of capturing prey using a folded, anterior raptorial appendage that looks superficially like the foreleg of a praying mantis. -
Settlement-Driven, Multiscale Demographic Patterns of Large Benthic Decapods in the Gulf of Maine

Darling Marine Center, School of Marine Sciences, University of Maine, Walpole, ME 04573, USA Received 3 November 1998; received in revised form 30 April 1999; accepted 5 May 1999 Abstract Three decapod species in the Gulf of Maine (American lobster Homarus americanus Milne Edwards, 1837, rock crab Cancer irroratus Say, 1817, and Jonah crab Cancer borealis Stimpson, 1859) were investigated to determine how their patterns of settlement and post-settlement abundance varied at different spatial and temporal scales. Spatial scales ranged from centimeters to hundreds of kilometers. Abundances of newly settled and older (sum of several cohorts) individuals were measured at different substrata, depths, sites within and among widely spaced regions, and along estuarine gradients. Temporal scales ranged from weekly censuses of new settlers within a season to inter-annual comparisons of settlement strengths. Over the scales considered here, only lobsters and rock crabs were consistently abundant in their early post- settlement stages. Compared to rock crabs, lobsters settled at lower densities but in speci®c habitats and over a narrower range of conditions. The abundance and distribution of older individuals of both species were, however, similar at all scales. This is consistent with previous observations that, by virtue of high fecundity, rock crabs have high rates of settlement, but do not discriminate among habitats, and suffer high levels of post-settlement mortality relative to lobsters. -
Anchialine Cave Biology in the Era of Speleogenomics Jorge L

Bracken-Grissom1 1Department of Biological Sciences, Florida International University, Biscayne Bay Campus, North Miami FL 33181, USA 2Department of Marine Biology, Texas A&M University at Galveston, Galveston, TX 77553, USA Abstract: Anchialine caves contain haline bodies of water with underground connections to the ocean and limited exposure to open air. Despite being found on islands and peninsular coastlines around the world, the isolation of anchialine systems has facilitated the evolution of high levels of endemism among their inhabitants. The unique characteristics of anchialine caves and of their predominantly crustacean biodiversity nominate them as particularly interesting study subjects for evolutionary biology. However, there is presently a distinct scarcity of modern molecular methods being employed in the study of anchialine cave ecosystems. The use of current and emerging molecular techniques, e.g., next-generation sequencing (NGS), bestows an exceptional opportunity to answer a variety of long-standing questions pertaining to the realms of speciation, biogeography, population genetics, and evolution, as well as the emergence of extraordinary morphological and physiological adaptations to these unique environments. The integration of NGS methodologies with traditional taxonomic and ecological methods will help elucidate the unique characteristics and evolutionary history of anchialine cave fauna, and thus the significance of their conservation in face of current and future anthropogenic threats. -

Progress in our understanding of phylogenetic relationships within the Crustacea is linked to continuing discoveries of new taxa, to advances in theory and to improvements in methodology. Six themes are discussed that serve to illustrate some of the major on-going controversies and unresolved problems in the field as well as to illustrate changes that have taken place since the time of Linnaeus. These themes are: 1. the treatment of parasitic Crustacea, 2. the affinities of the Remipedia, 3. the validity of the Entomostraca, 4. exopodites and epipodites, 5. using larval characters in estimating phylogenetic rela- tionships, and 6. fossils and the crustacean stem-lineage. It is concluded that the development of the stem lineage concept for the Crustacea has been dominated by consideration of taxa known only from larval or immature stages. -

The crustacean order Bathynellacea is a primitive group of subterranean aquatic (stygobitic) invertebrates that typically inhabits freshwater interstitial spaces in alluvia. A striking diversity of species from the bathynellacean family Parabathynellidae have been found in the calcretes of the Yilgarn palaeodrainage system in Western Australia. Taxonomic studies show that most species are restricted in their distribution to a single calcrete, which is consistent with the findings of other phylogeographic studies of stygofauna. In this, the first molecular phylogenetic and phylogeographic study of interspecific relationships among parabathynellids, we aimed to explore the hypothesis that species are short-range endemics and restricted to single calcretes, and to investigate whether there were previously unidentified cryptic species. Analyses of sequence data based on a region of the mitochondrial (mt) DNA cytochrome c oxidase 1 gene showed the existence of divergent mtDNA lineages and species restricted in their distribution to a single calcrete, in support of the broader hypothesis that these calcretes are equivalent to closed island habitats comprising endemic taxa. -

Oliphant, and Ingrid L. K. Iverson 1971 1 2 ABSTRACT The authors investigated food habits of albacore, Thunnus alalunga, bluefin tuna, Thunnus thynnus, and bonito, Sarda chiliensis, in the eastern North Pacific Ocean during 1968 and 1969. While most stomach samples came from fish caught commercially off southern California and Baja California, some came from fish taken in central Califor- nia, Oregon, and Washington waters. Standard procedures included enumeration of food items, volumetric analysis, and measure of frequency of occur- rence. The authors identified the majority of forage organisms to the specific level through usual taxonomic methods for whole animals. Identification of partially digested animals was accomplished through the use of otoliths for fish, beaks for cephalopods, and the exoskeleton for invertebrates. A pictorial guide to beaks of certain eastern Pacific cephalopods was prepared and proved helpful in identifying stomach contents. This guide is presented in this publication. The study indicates the prominent forage for bluefin tuna, bonito, and albacore in California waters is the northern anchovy, Engraulis mordax. 3 ACKNOWLEDGMENTS The Food Habits Study of Organisms of the California Current System, (Project 6–7-R), was an investigation estab- lished under contract between the U.S. -
<I>Cancer Irroratus</I>
BULLETIN OF MARINE SCIENCE, 36(3): 454-466,1985 RHYTHMICITY UNDER CONSTANT CONDITIONS IN THE ROCK CRAB, CANCER IRRORATUS Steve Rebach ABSTRACT The existence of activity rhythms in migratory populations of the rock crab, Cancer ir- roratus, which spend most of the year in deep water, was investigated. Mature individuals from the Mid-Atlantic Bight were tested under laboratory conditions of constant light (LL) and constant dark (DD) after an initial ambient photoperiod was presented. Activity levels were simultaneously monitored for 20 crabs maintained in separate compartments, using an infrared beam-break system. Activity was analyzed using an Enright periodogram. Activity under LL was at a relatively low level and with no rhythmic periodicity exhibited. In DD, activity was concentrated at approximately 25-h intervals, approximating a tidal period. Under ambient (natural photoperiod) conditions, a 24-h rhythm was present with activity greatest during the scotophase and with peaks at dawn and dusk. Possible advantages to the presence of a tidal rhythmicity in a deep water species are discussed and include temporal partitioning of the environment, a timekeeping mechanism for the initiation of migration, and an evolutionary or ecological remnant from shallow water populations. The common rock crab, Cancer irroratus, is found from Labrador to South Carolina (Haefner, 1976) and is most abundant from Maine to North Carolina. Rock crabs inhabit cold water (50-15°C, Haefner, 1976) and in the mid-Atlantic region they live at depths of 10-700 m (depending on age and season), with highest densities between 40 and 60 m (15-30 km offshore) (Musick and McEachran, 1972; Haefner, 1976). -

On the origin and evolution of Antarctic Peracarida (Crustacea, Malacostraca)* ANGELIKA BRANDT Zoological Institute and Zoological Museum, Martin-Luther-King-Platz 3, D-20146 Hamburg, Germany Dedicated to Jürgen Sieg, who silently died in 1996. He inspired this research with his important account of the zoogeography of the Antarctic Tanaidacea. SUMMARY: The early separation of Gondwana and the subsequent isolation of Antarctica caused a long evolutionary his- tory of its fauna. Both, long environmental stability over millions of years and habitat heterogeneity, due to an abundance of sessile suspension feeders on the continental shelf, favoured evolutionary processes of “preadapted“ taxa, like for exam- ple the Peracarida. This taxon performs brood protection and this might be one of the most important reasons why it is very successful (i.e. abundant and diverse) in most terrestrial and aquatic environments, with some species even occupying deserts. The extinction of many decapod crustaceans in the Cenozoic might have allowed the Peracarida to find and use free ecological niches. Therefore the palaeogeographic, palaeoclimatologic, and palaeo-hydrographic changes since the Palaeocene (at least since about 60 Ma ago) and the evolutionary success of some peracarid taxa (e.g. Amphipoda, Isopo- da) led to the evolution of many endemic species in the Antarctic. Based on a phylogenetic analysis of the Antarctic Tanaidacea, Sieg (1988) demonstrated that the tanaid fauna of the Antarctic is mainly represented by phylogenetically younger taxa, and data from other crustacean taxa led Sieg (1988) to conclude that the recent Antarctic crustacean fauna must be comparatively young. -
Arthropods of Elm Fork Preserve
Arthropods of Elm Fork Preserve Arthropods are characterized by having jointed limbs and exoskeletons. They include a diverse assortment of creatures: Insects, spiders, crustaceans (crayfish, crabs, pill bugs), centipedes and millipedes among others. Column Headings Scientific Name: The phenomenal diversity of arthropods, creates numerous difficulties in the determination of species. Positive identification is often achieved only by specialists using obscure monographs to ‘key out’ a species by examining microscopic differences in anatomy. For our purposes in this survey of the fauna, classification at a lower level of resolution still yields valuable information. For instance, knowing that ant lions belong to the Family, Myrmeleontidae, allows us to quickly look them up on the Internet and be confident we are not being fooled by a common name that may also apply to some other, unrelated something. With the Family name firmly in hand, we may explore the natural history of ant lions without needing to know exactly which species we are viewing. In some instances identification is only readily available at an even higher ranking such as Class. Millipedes are in the Class Diplopoda. There are many Orders (O) of millipedes and they are not easily differentiated so this entry is best left at the rank of Class. A great deal of taxonomic reorganization has been occurring lately with advances in DNA analysis pointing out underlying connections and differences that were previously unrealized. For this reason, all other rankings aside from Family, Genus and Species have been omitted from the interior of the tables since many of these ranks are in a state of flux. -
