N. Bergman*†‡, M. J. Lajeunesse* and P. J. Motta* *University of South Florida, Department of Integrative Biology, 4202 East Fowler Avenue, Tampa, FL 33620, U.S.A. and †Florida Fish and Wildlife Conservation Commission, Florida Fish and Wildlife Research Institute, 100 Eighth Avenue S.E., Saint Petersburg, FL 33701, U.S.A. (Received 16 February 2017, Accepted 15 May 2017) This study examined the minimum force required of functional teeth and replacement teeth in the tiger shark Galeocerdo cuvier and the sandbar shark Carcharhinus plumbeus to penetrate the scales and muscle of sheepshead Archosargus probatocephalus and pigfish Orthopristis chrysoptera. Penetra- tion force ranged from 7·7–41·9and3·2–26·3 N to penetrate A. probatocephalus and O. chrysoptera, respectively. Replacement teeth required significantly less force to penetrate O. chrysoptera for both shark species, most probably due to microscopic wear of the tooth surfaces supporting the theory shark teeth are replaced regularly to ensure sharp teeth that are efficient for prey capture. © 2017 The Fisheries Society of the British Isles Key words: biomechanics; bite force; Elasmobranchii; teleost; tooth morphology. INTRODUCTION Research on the functional morphology of feeding in sharks has typically focused on the kinematics and mechanics of cranial movement (Ferry-Graham, 1998; Wilga et al., 2001; Motta, 2004; Huber et al., 2005; Motta et al., 2008), often neglecting to integrate the function of teeth (but see Ramsay & Wilga, 2007; Dean et al., 2008; Whitenack et al., 2011).

Feeding habits of the leopard grouper, Mycteroperca rosacea (Actinopterygii: Perciformes: Epinephelidae), in the central Gulf of California, BCS, Mexico. Acta Ichthyol. Piscat. 49 (1): 9–22. Background. The leopard grouper, Mycteroperca rosacea (Streets, 1877), is endemic to north-western Mexico and has high commercial value. Although facts of its basic biology are known, information on its trophic ecology, in particular, is scarce. The objective of the presently reported study was to characterize the feeding habits of M. rosacea through the analysis of stomach contents, and to determine possible variations linked to sex (male or female), size (small, medium, or large), or season (spring, summer, autumn, or winter), in order to understand the trophic role that this species plays in the ecosystem where it is found. Materials and methods. Fish were captured monthly, from March 2014 to May 2015 by spearfishing in Santa Rosalía, BCS, Mexico. Percentages by the number, by weight, and frequency of appearance of each food category, the index of relative importance (%IRI), and prey-specific index of relative importance (%PSIRI) were used to determine the importance of each prey item in the leopard grouper diet.

    State of Oregon The ORE BIN· Department of Geology Volume 34,no. 10 and Mineral Industries 1069 State Office BI dg. October 1972 Portland Oregon 97201 FOSSil SHARKS IN OREGON Bruce J. Welton* Approximately 21 species of sharks, skates, and rays are either indigenous to or occasionally visit the Oregon coast. The Blue Shark Prionace glauca, Soup-fin Shark Galeorhinus zyopterus, and the Dog-fish Shark Squalus acanthias commonly inhabit our coastal waters. These 21 species are represented by 16 genera, of which 10 genera are known from the fossi I record in Oregon. The most common genus encountered is the Dog-fish Shark Squalus. The sharks, skates, and rays, (all members of the Elasmobranchii) have a fossil record extending back into the Devonian period, but many major groups became extinct before or during the Mesozoic. A rapid expansion in the number of new forms before the close of the Mesozoic gave rise to practically all the Holocene families living today. Paleozoic shark remains are not known from Oregon, but teeth of the Cretaceous genus Scapanorhyn­ chus have been collected from the Hudspeth Formation near Mitchell, Oregon. Recent work has shown that elasmobranch teeth occur in abundance west of the Cascades in marine Tertiary strata ranging in age from late Eocene to middle Miocene (Figures 1 and 2). All members of the EIasmobranchii possess a cartilaginous endoskeleton which deteriorates rapidly upon death and is only rarely preserved in the fossil record. Only under exceptional conditions of preservation, usually in a highly reducing environment, will cranial or postcranial elements be fossilized.

CALIFORNIA MARINE FISH LANDINGS FOR 1972 LEO PINKAS Marine Resources Region 1.1. INTRODUCTION The protection, propagation, and wise utilization of California's living marine resources (established as common property by statute, Section 1600, Fish and Game Code) is dependent upon the welding of biological, environment- al, economic, and sociological factors. Fundamental to each of these factors, as well as the entire management pro- cess, are harvest records. The California Department of Fish and Game began gathering commercial fisheries land- ing data in 1916. Commercial fish catches were first published in 1929 for the years 1926 and 1927. This report, the 32nd in the landing series, is for the calendar year 1972. It summarizes commercial fishing activities in marine as well as fresh waters and includes the catches of the sportfishing partyboat fleet. Preliminary landing data are published annually in the circular series which also enumerates certain fishery products produced from the catch.

  • Re-Evaluation of Pachycormid Fishes from the Late Jurassic of Southwestern Germany
    Editors' choice Re-evaluation of pachycormid fishes from the Late Jurassic of Southwestern Germany ERIN E. MAXWELL, PAUL H. LAMBERS, ADRIANA LÓPEZ-ARBARELLO, and GÜNTER SCHWEIGERT Maxwell, E.E., Lambers, P.H., López-Arbarello, A., and Schweigert G. 2020. Re-evaluation of pachycormid fishes from the Late Jurassic of Southwestern Germany. Acta Palaeontologica Polonica 65 (3): 429–453. Pachycormidae is an extinct group of Mesozoic fishes that exhibits extensive body size and shape disparity. The Late Jurassic record of the group is dominated by fossils from the lithographic limestone of Bavaria, Germany that, although complete and articulated, are not well characterized anatomically. In addition, stratigraphic and geographical provenance are often only approximately known, making these taxa difficult to place in a global biogeographical context. In contrast, the late Kimmeridgian Nusplingen Plattenkalk of Baden-Württemberg is a well-constrained locality yielding hundreds of exceptionally preserved and prepared vertebrate fossils. Pachycormid fishes are rare, but these finds have the potential to broaden our understanding of anatomical variation within this group, as well as provide new information regarding the trophic complexity of the Nusplingen lagoonal ecosystem. Here, we review the fossil record of Pachycormidae from Nusplingen, including one fragmentary and two relatively complete skulls, a largely complete fish, and a fragment of a caudal fin. These finds can be referred to three taxa: Orthocormus sp., Hypsocormus posterodorsalis sp. nov., and Simocormus macrolepidotus gen. et sp. nov. The latter taxon was erected to replace “Hypsocormus” macrodon, here considered to be a nomen dubium. Hypsocormus posterodorsalis is known only from Nusplingen, and is characterized by teeth lacking apicobasal ridging at the bases, a dorsal fin positioned opposite the anterior edge of the anal fin, and a hypural plate consisting of a fused parhypural and hypurals.
