www.shark-references.com Version 13.01.2017 Bibliography database of living/fossil sharks, rays and chimaeras (Chondrichthyes: Elasmobranchii, Holocephali) Papers of the year 2016 published by Jürgen Pollerspöck, Benediktinerring 34, 94569 Stephansposching, Germany and Nicolas Straube, Munich, Germany ISSN: 2195-6499 copyright by the authors 1 please inform us about missing papers: [email protected] www.shark-references.com Version 13.01.2017 Abstract: This paper contains a collection of 803 citations (no conference abstracts) on topics related to extant and extinct Chondrichthyes (sharks, rays, and chimaeras) as well as a list of Chondrichthyan species and hosted parasites newly described in 2016. The list is the result of regular queries in numerous journals, books and online publications. It provides a complete list of publication citations as well as a database report containing rearranged subsets of the list sorted by the keyword statistics, extant and extinct genera and species descriptions from the years 2000 to 2016, list of descriptions of extinct and extant species from 2016, parasitology, reproduction, distribution, diet, conservation, and taxonomy. The paper is intended to be consulted for information. In addition, we provide information on the geographic and depth distribution of newly described species, i.e. the type specimens from the year 1990- 2016 in a hot spot analysis. Please note that the content of this paper has been compiled to the best of our abilities based on current knowledge and practice, however, -

First Baby Zebra Sharks Born from Artificial Insemination Debut at the Aquarium of the Pacific on Tuesday, January 27
Contacts: Marilyn Padilla / Claire Atkinson / Adrian Samora Aquarium of the Pacific (562) 951-1684 / (562) 951-1678 / (562) 951-3197 [email protected] / [email protected] / [email protected] First Baby Zebra Sharks Born From Artificial Insemination Debut at the Aquarium of the Pacific on Tuesday, January 27 The Aquarium breeds a large shark species through artificial insemination January 26, 2015, Long Beach, CA—The Aquarium of the Pacific is announcing that it is the first to be able to successfully reproduce zebra sharks through artificial insemination. More than 100 million sharks in the wild are killed annually due to human impact. Being able to artificially inseminate large shark species like the zebra shark can further research in helping dwindling shark populations in the wild. The 10-month-old sharks are slated to go on exhibit in the Aquarium’s Shark Lagoon on Tuesday, January 27. Fern, approximately 20 years old, is the mother of the two female sharks. Fern arrived to the Aquarium in 1997. She was inseminated in September 2013, and both babies hatched from their eggs in late March of 2014. The Aquarium’s experts have been caring for the youngsters in their behind-the-scenes shark nursery. The zebra shark pups are now about 2-and-a-half to 3 feet long and are now ready to be introduced in the shallow pools in Shark Lagoon. The public will be able to see these special sharks when the aquarium opens at 9:00 a.m. on Tuesday. The 140-pound and 7-and-a-half-foot long mother zebra shark can be seen swimming in the Aquarium’s Shark Lagoon exhibit with other large sharks. -

Nair and P.U Zacharia Central Marine Fisheries Research Institute, Kochi-682 018 Introduction eyed, stomachless, deep-sea creatures that possess an upper jaw which is fused to its cranium (unlike in sharks). The term Elasmobranchs or chondrichthyans refers to the The great majority of the commercially important species of group of marine organisms with a skeleton made of cartilage. chondrichthyans are elasmobranchs.

The chondrichthyans which are placed in Class of the relationships and identity of different organisms. Elasmobranchii are grouped into two main subdivisions Classification of elasmobranchs certainly does not evade this Holocephalii (Chimaeras or ratfishes and elephant fishes) process, and species are sometimes lumped in with other with three families and approximately 37 species inhabiting species, or renamed, or assigned to different families and deep cool waters; and the Elasmobranchii, which is a large, other taxonomic groupings. It is certain, however, that such diverse group (sharks, skates and rays) with representatives revisions will clarify our view of the taxonomy and phylogeny in all types of environments, from fresh waters to the bottom (evolutionary relationships) of elasmobranchs, leading to a of marine trenches and from polar regions to warm tropical better understanding of how these creatures evolved. -

Oil Extraction and Derivatization Method: a Review
Open Access Journal of Science Review Article Open Access Oil extraction and derivatization method: a review Abstract Volume 4 Issue 3 - 2020 The objective of this work is to analyze and present the main methods of oil extraction. Pedro César Quero-Jiménez,1,3 Lester The present study suggests that different methods could be used to extract oil for food Alejandro Arias Felipe,2 Lisyaulen Rega and feed purposes. The method to be used for the extraction depends on several factors, 3 among which its cost and the materials to be used stand out.

Florida's Fintastic Sharks and Rays Lesson and Activity Packet
Florida's Fintastic Sharks and Rays An at-home lesson for grades 3-5 Produced by: This educational workbook was produced through the support of the Indian River Lagoon National Estuary Program. 1 What are sharks and rays? Believe it or not, they’re a type of fish! When you think “fish,” you probably picture a trout or tuna, but fishes come in all shapes and sizes. All fishes share the following key characteristics that classify them into this group: Fishes have the simplest of vertebrate hearts with only two chambers- one atrium and one ventricle. The spine in a fish runs down the middle of its back just like ours, making fish vertebrates. All fishes have skeletons, but not all fish skeletons are made out of bones. Some fishes have skeletons made out of cartilage, just like your nose and ears. Fishes are cold-blooded. Cold-blooded animals use their environment to warm up or cool down. Fins help fish swim. Fins come in pairs, like pectoral and pelvic fins or are singular, like caudal or anal fins. Later in this packet, we will look at the different types of fins that fishes have and some of the unique ways they are used. 2 Placoid Ctenoid Ganoid Cycloid Hard protective scales cover the skin of many fish species. Scales can act as “fingerprints” to help identify some fish species. There are several different scale types found in bony fishes, including cycloid (round), ganoid (rectangular or diamond), and ctenoid (scalloped). Cartilaginous fishes have dermal denticles (Placoid) that resemble tiny teeth on their skin. -
