BONY FISHES 602 Bony Fishes
click for previous page BONY FISHES 602 Bony Fishes GENERAL REMARKS by K.E. Carpenter, Old Dominion University, Virginia, USA ony fishes constitute the bulk, by far, of both the diversity and total landings of marine organisms encoun- Btered in fisheries of the Western Central Atlantic.They are found in all macrofaunal marine and estuarine habitats and exhibit a lavish array of adaptations to these environments. This extreme diversity of form and taxa presents an exceptional challenge for identification. There are 30 orders and 269 families of bony fishes presented in this guide, representing all families known from the area. Each order and family presents a unique suite of taxonomic problems and relevant characters. The purpose of this preliminary section on technical terms and guide to orders and families is to serve as an introduction and initial identification guide to this taxonomic diversity. It should also serve as a general reference for those features most commonly used in identification of bony fishes throughout the remaining volumes. However, I cannot begin to introduce the many facets of fish biology relevant to understanding the diversity of fishes in a few pages. For this, the reader is directed to one of the several general texts on fish biology such as the ones by Bond (1996), Moyle and Cech (1996), and Helfman et al.(1997) listed below. A general introduction to the fisheries of bony fishes in this region is given in the introduction to these volumes. Taxonomic details relevant to a specific family are explained under each of the appropriate family sections. The classification of bony fishes continues to transform as our knowledge of their evolutionary relationships improves. -

ZooKeys 412: 41–57. doi: 10.3897/zookeys.412.7245 Abstract We describe a new species of amblyopsid cavefish (Percopsiformes: Amblyopsidae) in the genus Amblyopsis from subterranean habitats of southern Indiana, USA. The Hoosier Cavefish, Amblyopsis hoosieri sp. n., is distinguished from A. spelaea, its only congener, based on genetic, geographic, and morphological evi- dence. Several morphological features distinguish the new species, including a much plumper, Bibendum- like wrinkled body with rounded fins, and the absence of a premature stop codon in the gene rhodopsin. -

I hypothesize that finfold reabsorption is part of the initial patterning of the median fins,and that caspase-3, an apoptosis marker, will be expressed in the fin fold during reabsorption. I analyzed time series of larvae in the first20-days post hatch (dph) to determine timing of median findevelopment in a basal bony fish- sturgeon- and in zebrafish, a derived bony fish. I am expecting the general activation pathway to be conserved in both fishesbut, the timing and location of cell death to differ.The dorsal fin foldis the firstto be reabsorbed in the sturgeon starting at 2 dph and rays formed at 6dph. This was closely followed by the anal finat 3 dph, rays at 9 dph and only later, at 6dph, does the caudal fin start forming and rays at 14 dph. -

Although many batoid species are generated by either oscillating or undulating expanded pectoral fins accurately described by these two extreme modes, several species that form a disc. Only one previous study of the freshwater stingray has fall into a continuum between 0.5 and 1.0 wave, and are defined as quantified three-dimensional motions of the wing, and no comparable ‘semi-oscillators’ (Schaefer and Summers, 2005). data are available for marine batoid species that may differ The mechanics of propulsion in cartilaginous fishes have been considerably in their mode of locomotion.

Bony Fish Guide
This guide will help you to complete the Bony Fish Observation Worksheet. Bony Fish Guide Fish (n.) An ectothermic (cold-blooded) vertebrate (with a backbone) aquatic (lives in water) animal that moves with the help of fins (limbs with no fingers or toes) and breathes with gills. This definition might seem very broad, and that is because fish are one of the most diverse groups of animals on the planet—there are a lot of fish in the sea (not to mention rivers, lakes and ponds). In fact, scientists count at least 32,000 species of fish—more than any other type of vertebrate. Fish are split into three broad classes: Jawless Fish Cartilaginous Fish Bony Fish (hagfish, lampreys, etc.) (sharks, rays, skates, etc.) (all other fish) This guide will focus on the Bony Fish. There are at least 28,000 species of bony fish, and they are found in almost every naturally occurring body of water on the planet. Bony fish range in size: • Largest: ocean sunfish (Mola mola), 11 feet, over 5,000 pounds • Smallest: dwarf pygmy goby (Pandaka pygmaea), ½ inch, a fraction of an ounce (This image is life size.) The following guide will help you learn more about the bony fish you can find throughout the New England Aquarium. Much of the guide is keyed to the Giant Ocean Tank, but can be applied to many kinds of fish. Even if you know nothing about fish, you can quickly learn a few things: The shape of a fish’s body, the position of its mouth and the shape of its tail can give you many clues as to its behavior and adaptations. -

Oxyeleotris Colasi (Teleostei: Eleotridae), a New Blind Cave Fish from Lengguru in West Papua, Indonesia
Oxyeleotris colasi (Teleostei: Eleotridae), a new blind cave fish from Lengguru in West Papua, Indonesia by Laurent POUYAUD* (1), KADARUSMAN (1, 2), Renny K. HADIATY (3), Jacques SLEMBROUCK (1), Napoleon LEMAUK (4), Ruby V. KUSUMAH (5) & Philippe KEITH (6) ABSTRACT. - Oxyeleotris colasi is the first hypogean fish recorded from West Papua. The habitat consists of a freshwater pool in the cave of Jabuenggara located in the heart of Seraran anticline in the limestone karst of Lengguru. The new spe- cies is most closely related to the blind cave fishO. caeca described by Allen (1996) from eastern New Guinea. The two troglomorphic species are hypothesised to be related to O. fimbriata, an epigean freshwater gudgeon that ranges widely in New Guinea and northern Australia (Allen, 1996). Oxyeleotris colasi differs from its congeners by the absence of eyes, its skin and fins being totally depigmented, the presence of a well developed sensory papillae system partly consisting of low raised fleshy ridges on each side of the head, a reduced number of cephalic sensory pores, a reduced number of scales on head and body, a long head with a short snout length, a narrow mouth width and a long upper jaw length, body shape with a shallow anterior body depth and narrow body width, a long and deep caudal peduncle, long predorsal and prepectoral lengths, and a long pectoral fin. RÉSUMÉ. - Oxyeleotris colasi, une nouvelle espèce de poisson cavernicole de Lengguru en Papouasie occidentale (Teleostei : Eleotridae). Oxyeleotris colasi est la première espèce de poisson hypogée décrite de Papouasie occidentale. Elle a été capturée dans un trou d’eau douce situé dans la grotte de Jabuenggara au cœur de l’anticlinal de Seraran dans le karst de Lengguru. -
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. -
