Teleosts comprise 517 families, of which 69 are extinct, leaving 448 extant families; of these, about 43% have no fossil record.

This type of tail primitively results from an ontogenetic fusion of centra (bodies of vertebrae) and the possession of paired bracing bones located bilaterally along the dorsal region of the caudal skeleton, derived ontogenetically from the neural arches (uroneurals) of the ural (tail) centra.

The equations = − fishery between total length (TL) and weight (W) were: log10 W 2.326 + = − management, 3.139 log10 TL for males and log10 W 2.366 + 3.168 log10 TL for fe- introduced males. There were highly significant differences between the sexes and species, for both sexes the value of b (slope of the log (TL-W regression) was Lake Trasimeno greater than 3 (3.139 for males and 3.168 for females), indicating positive allometric growth. The parameters of the theoretical growth curve were: −1 TLt = 10.03 cm; k = 0.18 yr , t0 = −0.443 yr and Φ = 1.65. Monthly trends of overall condition and the gonadosomatic index (GSI) indicated that the reproductive period occurred from March to September. Analy- sis of back-calculated lengths indicated the occurrence of a reverse Lee’s phenomenon.

In 2015 the Global Ranavirus Reporting System (GRRS) was established as a centralized, open access, online database for reports of the presence (and absence) of ranavirus around the globe. The GRRS has multiple data layers (e.g., location, date, host(s) species, and methods of detection) of use to those studying the epidemiol- ogy, ecology, and evolution of this group of viruses. Here we summarize the temporal, spatial, diag- nostic, and host-taxonomic patterns of ranavirus reports in the GRRS. The number, distribution, and host diversity of ranavirus reports have increased dramatically since the mid 1990s, presumably in response to increased interest in ranaviruses and the conservation of their hosts, and also the availability of molecular diagnostics. Yet there are clear geographic and taxonomic biases among the OPEN ACCESS reports. We encourage ranavirus researchers to add their studies to the portal because such collation can provide collaborative opportunities and unique insights to our developing knowledge of this For personal use only.

Generally, in this group, the upper jaw consists of the premaxilla, maxilla, and supramaxilla. The lower jaw consists of the dentary, anguloarticular, retroarticular, and sesamoid articular. In higher taxa, the premaxilla bears ascending, articular, and postmaxillary processes. The maxilla usually bears a ventral and a dorsal articular process. The supramaxilla is present only in some taxa. The dentary is usually toothed and bears coronoid and posteroventral processes. The retroarticular is small and located at the posteroventral corner of the anguloarticular.

Collette National Marine Fisheries Service Systematics Laboratory National Museum of Natural History, Washington, DC 20560–0153, U.S.A. email: [email protected] Needlefishes are a relatively small family of beloniform fishes (Rosen and Parenti 1981 [ref. 5538], Collette et al. 1984 [ref. 11422]) that differ from other members of the order in having both the upper and the lower jaws extended into long beaks filled with sharp teeth (except in the neotenic Belonion), the third pair of upper pharyngeal bones separate, scales on the body relatively small, and no finlets following the dorsal and anal fins. The nostrils lie in a pit anterior to the eyes. There are no spines in the fins. The dorsal fin, with 11–43 rays, and anal fin, with 12–39 rays, are posterior in position; the pelvic fins, with 6 soft rays, are located in an abdominal position; and the pectoral fins are short, with 5–15 rays. The lateral line runs down from the pectoral fin origin and then along the ventral margin of the body. The scales are small, cycloid, and easily detached. Precaudal vertebrae number 33–65, caudal vertebrae 19–41, and total verte- brae 52–97. Some freshwater needlefishes reach only 6 or 7 cm (2.5 or 2.75 in) in total length while some marine species may attain 2 m (6.5 ft).

  • Traveler Information
    Traveler Information QUICK LINKS Marine Hazards—TRAVELER INFORMATION • Introduction • Risk • Hazards of the Beach • Animals that Bite or Wound • Animals that Envenomate • Animals that are Poisonous to Eat • General Prevention Strategies Traveler Information MARINE HAZARDS INTRODUCTION Coastal waters around the world can be dangerous. Swimming, diving, snorkeling, wading, fishing, and beachcombing can pose hazards for the unwary marine visitor. The seas contain animals and plants that can bite, wound, or deliver venom or toxin with fangs, barbs, spines, or stinging cells. Injuries from stony coral and sea urchins and stings from jellyfish, fire coral, and sea anemones are common. Drowning can be caused by tides, strong currents, or rip tides; shark attacks; envenomation (e.g., box jellyfish, cone snails, blue-ringed octopus); or overconsumption of alcohol. Eating some types of potentially toxic fish and seafood may increase risk for seafood poisoning. RISK Risk depends on the type and location of activity, as well as the time of year, winds, currents, water temperature, and the prevalence of dangerous marine animals nearby. In general, tropical seas (especially the western Pacific Ocean) are more dangerous than temperate seas for the risk of injury and envenomation, which are common among seaside vacationers, snorkelers, swimmers, and scuba divers. Jellyfish stings are most common in warm oceans during the warmer months. The reef and the sandy sea bottom conceal many creatures with poisonous spines. The highly dangerous blue-ringed octopus and cone shells are found in rocky pools along the shore. Sea anemones and sea urchins are widely dispersed. Sea snakes are highly venomous but rarely bite.
