Common Mudpuppy PA’s Amphibian and Reptile Coloring Series Common Mudpuppy All About Me: Hi! I am a Mudpuppy. Only one other salamander in Pennsylvania, the Hellbender, grows larger than we do. As an adult, we reach an impressive 8 to 13 inches long. We are permanent larvae, using external gills our entire lives. We are thoroughly aquatic and nocturnal, although we may be active even during the day in muddy or turbid water. Our most striking characteristic are the large, feathery red gills billowing out from behind each side of our heads. Our legs are short but strong. Our tails are shaped like a rudder. Our tail fins are occasionally tinted with orange or reddish pigments. Our small eyes have no eyelids. We have four toes on the front and hind feet. We are gray to rusty brown on our backs with dark blue-black spots. Our spots have irregular edges and are separated from one another. Our pale bellies are usually gray and accented with dark spots. A dark stripe runs through each eye. Fifteen or 16 costal grooves mark each of our sides. In Pennsylvania, we appear primarily in the Ohio River and Lake Erie watersheds, both part of our original range. We are found in lakes, rivers and streams. Although we prefer clear, swift water, we can be found in waters ranging from shallow, muddy, ponds with thick stands of aquatic plants to cool, clear, deep pools and lakes. We like to spend our days hidden beneath underwater structures, venturing out at night in search of prey. We feed on just about any aquatic animal we can capture. Crayfish are a favorite food, but worms, insects, small fish, and fish eggs mix up our diet. www.fishandboat.com .

Buhlmann [SCDNR] Reviewed and Edited (2012): Stephen Bennett (SCDNR), Kurt A. Buhlmann (SREL), and Jeff Camper (Francis Marion University) DESCRIPTION Taxonomy and Basic Descriptions This guild contains 4 primary species: the flatwoods salamander, Carolina gopher frog, dwarf siren, and tiger salamander; and 2 secondary species: upland chorus frog and northern cricket frog. Primary species are high priority species that are directly tied to a unifying feature or habitat. Secondary species are priority species that may occur in, or be related to, the unifying feature at some time in their life. The flatwoods salamander—in particular, the frosted flatwoods salamander— and tiger salamander are members of the family Ambystomatidae, the mole salamanders. Both species are large; the tiger salamander is the largest terrestrial salamander in the eastern United States. The Photo by SC DNR flatwoods salamander can reach lengths of 9 to 12 cm (3.5 to 4.7 in.) as an adult. This species is dark, ranging from black to dark brown with silver-white reticulated markings (Conant and Collins 1991; Martof et al. 1980). The tiger salamander can reach lengths of 18 to 20 cm (7.1 to 7.9 in.) as an adult; maximum size is approximately 30 cm (11.8 in.).

  • Histological Observation of the External Gills of a Mexican Axolotl (Ambystoma Mexicanum) with Atypical Blood Vessels
    Naturalistae 23: 47-52 (Feb. 2019) © 2019 by Okayama University of Science, PDF downloadable at http://www1.ous.ac.jp/garden/ Original paper Histological observation of the external gills of a Mexican axolotl (Ambystoma mexicanum) with atypical blood vessels Saki YOSHIDA1 and Kazuyuki MEKADA1* Abstract: The external gills of captive Mexican axolotl (Ambystoma mexicanum) sometimes develop atypical blood vessels, the cause of which is unknown. We observed the external gill filaments of an individual animal with dilated blood vessels that formed a semicircle within the filament tissue. The positioning of the swollen blood vessels compressed the adjacent capillaries and connective tissues. Normal external gill filaments in urodelans contain a blood-vessel system with afferent and efferent arterioles that connect to circumvent the outer gill periphery. We infer that the dilated blood vessels in the axolotl originated from these arterioles. I. Introduction et al. 2015, Nowoshilow et al. 2018, Page et al. 2013, Voss et al. 2015).

J Morphol Sci 2018;35:142–152. Abstract Introduction Water pH affects the breeding, hatching, development, locomotion, mortality and habitat distributions of species in nature. The external gills of anuran tadpoles were studied by several authors in relation to abiotic factors. Exposure to low and high pH has been found to adversely affect the different tissues of various organisms. On that consideration, the present investigation was performed with tadpoles of the species Hyla annectans and Euphlyctis cyanophlyctis. Material and Methods The maximum and the minimum pH thresholds were determined prior to the detailed experiments on the effects of pH. The pH that demonstrated 50% mortality was taken as the minimum and maximum pH thresholds. The hatchlings of both the species were then subjected to different pH (based on the minimum and maximum pH thresholds). After 48 hours of exposure, the external gills of the hatchlings were anesthetized and observed under a scanning electron microscope. Keywords Results After 48 hours, clumping, overlapping and curling of the secondary filaments ► Hyla annectans of the external gills and epithelial lesions in response to both acidic and alkaline pH ► Euphlyctis were observed.

  • External Gills and Adaptive Embryo Behavior Facilitate Synchronous Development and Hatching Plasticity Under Respiratory Constraint
    3627 The Journal of Experimental Biology 211, 3627-3635 Published by The Company of Biologists 2008 doi:10.1242/jeb.020958 External gills and adaptive embryo behavior facilitate synchronous development and hatching plasticity under respiratory constraint Jessica R. Rogge and Karen M. Warkentin* Department of Biology, Boston University, Boston, MA 02215, USA 'Author for correspondence (e-mail: [email protected]) Accepted 22 September 2008 SUMMARY Plasticity in hatching timing allows embryos to balance egg- and larval-stage risks, and depends on the ability of hatching- competent embryos to continue developing in the egg. Hypoxia can slow development, kill embryos and induce premature hatching. For terrestrial eggs of red-eyed treefrogs, the embryonic period can extend ~50% longer than development to hatching competence, and development is synchronous across perivitelline oxygen levels (Po2) ranging from 0.5-16.5 kPa. Embryos maintain large external gills until hatching, then gills regress rapidly. We assessed the respiratory value of external gills using gill manipulations and closed-system respirometry. Embryos without external gills were oxygen limited in air and hatched at an external Po2 of 17kPa, whereas embryos with gills regulated their metabolism and remained in the egg at substantially lower Po2. By contrast, tadpoles gained no respiratory benefit from external gills. We videotaped behavior and manipulated embryos to test if they position gills near the air-exposed portion of the egg surface, where PQ2 is highest. Active embryos remained stationary for minutes in gills-at-surface positions. After manipulations and spontaneous movements that positioned gills in the 02-poor region of the egg, however, they returned their gills to the air-exposed surface within seconds.

    Salamanders of Tennessee: modified from Lisa Powers tnwildlife.org Follow links to Nongame The Salamanders of Tennessee Photo by John White Salamanders are the group of tailed, vertebrate animals that along with frogs and caecilians make up the class Amphibia. Salamanders are ectothermic (cold-blooded), have smooth glandular skin, lack claws and must have a moist environment in which to live. 1 Amphibian Declines Worldwide, over 200 amphibian species have experienced recent population declines. Scientists have reports of 32 species First discovered in 1967, the golden extinctions, toad, Bufo periglenes, was last seen mainly species of in 1987. frogs. Much attention has been given to the Anurans (frogs) in recent years, however salamander populations have been poorly monitored.

Their key role and high densities in many forests The stability in their counts and populations Their vulnerability to air and water pollution Their sensitivity as a measure of change The threatened and endangered status of several species Their inherent beauty and appeal as a creature to study and conserve. *Possible Factors Influencing Declines Around the World Climate Change Habitat Modification Habitat Fragmentation Introduced Species UV-B Radiation Chemical Contaminants Disease Trade in Amphibians as Pets *Often declines are caused by a combination of factors and do not have a single cause. Major Causes for Declines in Tennessee Habitat Modification -The destruction of natural habitats is undoubtedly the biggest threat facing amphibians in Tennessee. Housing, shopping center, industrial and highway construction are all increasing throughout the state and consequently decreasing the amount of available habitat for amphibians.

  • Vertebrate Respiratory System Gills
    Dr. Medhavi Sudarshan Assist Prof nd B.SC 2 Year, Paper IV Deapt of Zoology JNL College , Khagaul Comparative Anatomy – Vertebrate Respiratory System Respiratory system is a system consisting of specific organs and structures used for the process of respiration in an organism. Respiration is the process of obtaining oxygen from the external environment & eliminating CO2. External respiration - oxygen and carbon dioxide exchanged between the external environment & the body cells Internal respiration - cells use oxygen for ATP production (& produce carbon dioxide in the process) In vertebrates the skin may be respiratory (e.g., anurans), while in some fishes and aquatic turtles, the vascular rectum or cloaca is respiratory. But there are two main types of respiratory organs- gills for aquatic respiration and lungs for aerial respiration. Both gills and lungs may occur in the same animal. Accessory respiratory organs are also present in some vertebrates. In both kinds of respiration two conditions are essential; 1. The respiratory organs must have a rich blood supply with very thin moist epithelium covering the blood vessels so that these blood vessels are through into close contact with the environment (water or air). 2. The organs of respiration the blood vessels should be reduced to thin capillaries which expose a large surface area to the environment, so that blood is brought into close contact with the water or air in the respiratory organs. Gills Cartilaginous fishes: Septal gills. Cartilaginous fishes (Sharks) use gills to breathe rather than lungs. There is 5 to 7 gill arches, each bearing one gill slit and covered by the operculum, which acts as a lid over the gill.

    Sánchez‑Villagra and Werneburg Evo Edu Outreach (2016) 9:11 DOI 10.1186/s12052-016-0062-y REVIEW Open Access Mammalian organogenesis in deep time: tools for teaching and outreach Marcelo R. Sánchez‑Villagra1 and Ingmar Werneburg1,2,3,4* Abstract Mammals constitute a rich subject of study on evolution and development and provide model organisms for experi‑ mental investigations. They can serve to illustrate how ontogeny and phylogeny can be studied together and how the reconstruction of ancestors of our own evolutionary lineage can be approached. Likewise, mammals can be used to promote ’tree thinking’ and can provide an organismal appreciation of evolutionary changes. This subject is suitable for the classroom and to the public at large given the interest and familiarity of people with mammals and their closest relatives. We present a simple exercise in which embryonic development is presented as a transforma‑ tive process that can be observed, compared, and analyzed. In addition, we provide and discuss a freely available animation on organogenesis and life history evolution in mammals. An evolutionary tree can be the best tool to order and understand those transformations for different species. A simple exercise introduces the subject of changes in developmental timing or heterochrony and its importance in evolution. The developmental perspective is relevant in teaching and outreach efforts for the understanding of evolutionary theory today.

  • 2017 Hellbender Symposium Agenda
    Mississippi Museum of Natural Science 2148 Riverside Drive, Jackson, Mississippi June 19-21, 2017 Page 1 Artwork for the symposium logo was kindly provided by the Mississippi Museum of Natural Science’s in-house artist, Sam Beibers. You are welcome to use this illustration as long as it is not used for resale in any capacity. Please credit its use with the following: "Illustration: Sam Beibers". IF you need illustrations for any of your own projects, you may contact Sam at 601-826-9256 or [email protected]. In this illustration, Sam Beibers wanted to take a "color challenged" animal in situ and push those colors brighter than they normally would be. "I wanted the hellbender to have something of a regal look. Afterall, they are 'superstars' to many of us in the scientific community." The final illustration was painted in watercolor on thin, clay-coated bristol board. As the paint dries on a smooth surface that is not very porous, the paint tends to "sit" on the surface instead of soaking in. Therefore it often dries in visible puddles. Pencil was used to add some detail and emphasize some areas of shade. Beibers grew up in rural northwest Mississippi. Like most boys, he enjoyed catching tadpoles, building huts, and swinging on grapevines. After one miserable year of wildlife biology studies at junior college, he changed his major to art and has since gone on to paint and draw hundreds of flora and fauna illustrations, as well as landscapes, cityscapes, and portraits. He received his MA at Mississippi College. Page 2 The following sponsors (and/or representatives from these institutions) helped make this symposium a success.

Historically, the eastern tiger salamander’s (Ambystoma tigrinum), range originally encompassed 8 different counties in southern New Jersey. In 2018, tiger salamanders are now restricted to only 3 southern New Jersey counties (e.g., Cape May, Cumberland and Salem). Within these three counties the remaining populations are known to successfully breed at approximately 13 suitable wetland locations.
