Oldfield University of Michigan, Department of Ecology and Evolutionary Biology Museum of Zoology, 1109 Geddes Ave., Ann Arbor, MI 48109 U.S.A. E-mail: [email protected] A version of this article was published previously in two parts: Oldfield, R.G. 2005. Biology, husbandry, and reproduction of freshwater stingrays I.

Introduction In the freshwater aquarium, stingrays are among the most desired of unusual pets. Although a couple species have been commercially available for some time, they remain relatively uncommon in home aquariums. They are often avoided by aquarists due to their reputation for being fragile and difficult to maintain. As with many fishes that share this reputation, it is partly undeserved. A healthy ray is a robust animal, and problems are often due to lack of a proper understanding of care requirements. In the last few years many more species have been exported from South America on a regular basis. As a result, many are just recently being captive bred for the first time. These advances will be making additional species of freshwater stingray increasingly available in the near future. This article answers this newly expanded supply of wild-caught rays and an anticipated increased The underside is one of the most entertaining aspects of a availability of captive-bred specimens by discussing their stingray. In an aquarium it is possible to see the gill slits and general biology, husbandry, and reproduction in order watch it eat, as can be seen in this Potamotrygon motoro.

  • Hunting Tactics of Potamotrygonid Rays in the Upper Paraná River
    Neotropical Ichthyology, 7(1):113-116, 2009 Copyright © 2009 Sociedade Brasileira de Ictiologia Scientific Note Stirring, charging, and picking: hunting tactics of potamotrygonid rays in the upper Paraná River Domingos Garrone-Neto1 and Ivan Sazima2 Hunting tactics of potamotrygonid freshwater rays remain unreported under natural conditions. Three main foraging tactics of Potamotrygon falkneri and P. motoro are described here based on underwater observations in the upper Paraná River. Both species displayed similar behaviors. The most common tactic was to undulate the disc margins close to, or on, the bottom and thus stirring the substrate and uncovering hidden preys. Another tactic was to charge upon prey concentrated in the shallows. The least common tactic was to pick out prey adhered to the substrate. The first tactic is widespread in several species of marine rays in the Dasyatidae, whereas the remainder (especially picking up prey on substrata above water surface) may be restricted to the Potamotrygonidae. As táticas de caça de raias potamotrigonídeas permanecem sem registro sob condições naturais. Três táticas de forrageamento são aqui descritas para Potamotrygon falkneri e P. motoro, com base em observações subaquáticas no curso superior do rio Paraná. Ambas as espécies apresentaram comportamento semelhante. A tática mais comum foi a de ondular as margens do disco próximo ao, ou no, fundo e assim perturbando o substrato e revelando presas abrigadas. Outra tática foi a de investir sobre presas concentradas no raso. A tática menos frequente foi a de apanhar presas aderidas ao substrato. A primeira tática é comum em diversas espécies de raias marinhas da família Dasyatidae, ao passo que as outras duas (em particular apanhar presas em substratos acima da superfície da água) podem estar restritas a Potamotrygonidae.

Thorson School of Life Sciences, University of Nebraska-Lincoln, Lincoln, Nebraska 68588 ABSTRACT: Two new tetraphyllidean cestodes are described from the freshwater stingray Potamotrygon magdalenae from Colombia. The new genus Potamotrygonocestusis proposed for P. magdalenensis, which differs from Pedibothrium by having a bilobed rather than X-shaped ovary, and simple rather than bifid hooks.

  • Potamotrygon Ocellata ERSS
    Potamotrygon ocellata (a stingray, no common name) Ecological Risk Screening Summary U.S. Fish & Wildlife Service, August 2012 Revised, September 2018 Web Version, 3/2/2021 Organism Type: Fish Overall Risk Assessment Category: Uncertain 1 Native Range and Status in the United States Native Range From Froese and Pauly (2018): “Known from the Pedreira River in Amapá and south of Mexiana Island, Pará [Brazil] [Carvalho et al. 2003]. Type locality, south of Mexiana Island at mouth of Amazon river [Brazil] [Carvalho et al. 2003].” Status in the United States No records of Potamotrygon ocellata in the wild or in trade in the United States were found. The Florida Fish and Wildlife Conservation Commission has listed the freshwater stingray Potamotrygon ocellata as a conditional species. Prohibited nonnative species (FFWCC 2018), “are considered to be dangerous to the ecology and/or the health and welfare of the people of Florida. These species are not allowed to be personally possessed, although exceptions are made 1 by permit from the Executive Director for research, commercial use (with security measures to prevent escape or release) or public exhibition purposes.” From Arizona Office of the Secretary of State (2013): “I. Fish listed below are considered restricted live wildlife: […] 32. All species of the family Potamotrygonidae. Common name: stingray.” From California Department of Fish and Wildlife (2019): “It shall be unlawful to import, transport, or possess live animals restricted in subsection (c) below except under permit issued by the department. […] Restricted species include: […] Family Potamotrygonidae-River stingrays: All species (D).” From Georgia DNR (2020): “The exotic species listed below, except where otherwise noted, may not be held as pets in Georgia.

The new genus, Heliotrygon, n. gen., and its two new species, Heliotrygon gomesi, n. sp. (type-species) and Heliotrygon rosai, n. sp., are compared to all genera and species of potamotrygonids, based on revisions in progress. Some of the derived features of Heliotrygon include its unique disc pro- portions (disc highly circular, convex anteriorly at snout region, its width and length very similar), extreme subdivision of suborbital canal (forming a complex honeycomb-like pattern anterolaterally on disc), stout and triangular pelvic girdle, extremely reduced caudal sting, basibranchial copula with very slender and acute anterior extension, and precerebral and frontoparietal fontanellae of about equal width, tapering very little posteriorly.
