Balaenoptera Bonaerensis – Antarctic Minke Whale
Balaenoptera bonaerensis – Antarctic Minke Whale compared to B. bonaerensis. This smaller form, termed the “Dwarf” Minke Whale, may be genetically different from B. bonaerensis, and more closely related to the North Pacific Minke Whales, and thus has been classified B. acutorostrata (Wada et al. 1991; IWC 2001). This taxonomic position, although somewhat controversial, has been accepted by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), and the Convention on Migratory Species (CMS). Assessment Rationale The current IWC global estimate of abundance of Antarctic Dr. Meike Scheidat Minke Whales is about 500,000 individuals. The abundance estimates declined from about 700,000 for the second circumpolar set of abundance survey cruises Regional Red List status (2016) Least Concern* (1985/86 to 1990/91) to about 500,000 for the third National Red List status (2004) Least Concern (1991/92 to 2003/04). Although this decline was not statistically significant, the IWC Scientific Committee does Reasons for change No change consider these results to reflect a change. However, Global Red List status (2008) Data Deficient whether this change is genuine or attributed to greater proportions of pack ice limiting the survey extent, has not TOPS listing (NEMBA) (2007) None yet been determined. More detailed results from an CITES listing (1986) Appendix I assessment model are available for the mid-Indian to the mid-Pacific region, and suggest that the population Endemic No increased to a peak in 1970 and then declined, with it *Watch-list Data being unclear whether this decline has levelled off or is still continuing past 2000. -

Published June 1997) ABSTRACT Concentrations and patterns of chlorinated biphenyls (CBS) and other persistent organochlorine compounds (OCs) were determined from small blubber biopsy samples collected from northwestern Atlantic minke (Balaenoptera acuros- trata) , fin (Balaenoptera physalus), blue (Balaenoptera musculus) , and humpback (Megaptera novaeangliae) whales summering in the Gurf of St. Lawrence, Quebec. Concentrations of CPCB (sum of 19 congeners) in biopsy samples ranged from 0.2-10 pg g-’ lipid, and congeners 52, 101, 118, 153, 138 and 180 accounted for 79% of CPCB. Mean concentration of the sum of non- ortho CB congeners in selected biopsy samples was 2 ng g-t lipid, and relative concentrations of these analytes were: 77 > 126 > 81> 169. Concentrations of XDDT ranged from 0.613 pg g-t lipid, and the average proportion of DDE to CDDT was 72%. All other organochlorine analytes were present at concentra- tions below 2 pg g-t lipid. On average, cis-nonachlor, trans-nonachlor and oxy- chlordane accounted for 27, 26 and 23%, respectively, of the chlordane-related analytes, and cl-hexachlorocyclohexane (HCH) comprised 67% of XHCH. -

For The physiological advantages and disadvantages associated with diving mammals, benefits conferred by large body size include different body sizes have wide-ranging effects, from behavior to life reduced transport costs and enhanced breath-holding capacity, history. For example, the smallest animals have the lowest absolute thereby increasing overall foraging efficiency. Rorqual whales feed energetic demands (Kelt and Van Vuren, 1999), yet they may also by engulfing a large mass of prey-laden water at high speed and struggle with thermoregulation and be forced to compensate by filtering it through baleen plates. However, as engulfment capacity increasing their metabolism (Scholander et al., 1950; Taylor et al., increases with body length (engulfment volume∝body length3.57), the 1980). Small size enables high performance maneuverability and surface area of the baleen filter does not increase proportionally agility (Domenici, 2001), but may limit maximum attainable speeds (baleen area∝body length1.82), and thus the filtration time of larger (Carrier, 1994; Hirt et al., 2017). -
A Brief Review of the Genetic Studies on Dwarf Minke Whale Based on Jarpa Samples
SC/D06/J8 A BRIEF REVIEW OF THE GENETIC STUDIES ON DWARF MINKE WHALE BASED ON JARPA SAMPLES Luis A. Pastene Institute of Cetacean Research, Toyomi-cho 4-5, Chuo-ku, Tokyo 104-0055, Japan ABSTRACT Prior to the JARPA surveys ‘dwarf’ minke whales were only believed to be found between 7-41°S. However the locality of the JARPA catches in Areas IV and V was mainly between 55-62°S (one animal was caught at 65°S), showing that the ‘dwarf’ minke whale is found much further south than shown by the previous data. A total of 16 ‘dwarf’ minke whales were sampled by JARPA and these animals were examined genetically with the purpose to investigate their relationship to the southern ‘ordinary’ minke whale and to minke whales in the Northern Hemisphere. Early studies showed that the degree of mtDNA divergence between both southern minke whales was large and similar to that found between southern ‘ordinary’ minke whale and Northern Hemisphere minke whales. Phylogenetic analyses showed that the ‘dwarf’ minke whale was more closely related to Northern Hemisphere minke whales. In 1993 the Scientific Committee recommended the inclusion of the ‘dwarf’ minke whale in the Schedule, so that catch limits for Antarctic minke whales recognise the distinction between the two southern minke whales. The genetic analysis conducted using JARPA samples of the southern ‘ordinary’ and ‘dwarf’ minke whales assisted greatly to the taxonomic review of minke whale conducted by Rice (1998), which confirmed the existence of two species, the larger, Antarctic minke whale Balaenoptera bonaerensis confined to the Southern Hemisphere, and the smaller, common minke whale B. -
Fin Whale Balaenoptera Physalus
Natural Heritage Fin Whale & Endangered Species Balaenoptera physalus Program State Status: Endangered www.mass.gov/nhesp Federal Status: Endangered Massachusetts Division of Fisheries & Wildlife DESCRIPTION: Fin Whales can weigh between 40 and 80 tons and measure 22 to 26 meters long, second in size only to the Blue Whale. Females tend to be slightly larger than males by 5-10%. Fin Whales have a sleek, streamlined body with a V-shaped head and are dark grey to brown on top, with white underneath. They have a tall, hooked, dorsal fin located two-thirds of the way down their body. Fin Whales are commonly called Razorbacks for the ridges on the middle of the back behind the dorsal fin. The unique asymmetrical coloration on the head easily separates this species from all of the other baleen whales. On the right side, the lower jaw is white, and the baleen plates in the front half of the mouth are also white, but abruptly change to dark Photo courtesy of NOAA in the back half of the mouth. By contrast, the lower left jaw is gray and all of the baleen plates on the left side are dark. This coloration may aid in herding fish during east of Boston and Cape Ann. Although there are feeding, although its primary purpose is unknown. seasonal fluctuations, the Fin Whale is most common in New England from April to November.

Dear Activist, Thank You for Hosting a Whale Watching House Party. Your
702 H Street, NW, Suite 300, Washington, DC 20001 Tel: 202-462-1177 • Fax: 202-462-4507 1-800-326-0959 • www.greenpeaceusa.org Dear Activist, Thank you for hosting a Whale Watching House Party. Your participation is key to putting an end to the senseless business of killing whales once and for all. Greenpeace and whale protection have gone hand-in-hand since 1975 when we launched our first anti-whaling campaign. This winter, we once again are in the Southern Ocean bearing witness to the whale slaughter and giving our all to help as many whales escape the harpoons as possible. Our ships, the Arctic Sunrise and the Esperanza, left Cape Town in South Africa on November 20th to intercept the Japanese whaling fleet. On December 21st, we made first contact with the whalers and we have doggedly pursued them since. Greenpeace activists have successfully kept the whaling fleet on the run, positioned themselves in the path between harpoons and whales, and documented whales in agony from exploding harpoons. But, bearing witness to the whale slaughter on the high seas is not enough. We need you. Whaling is big business and we, consumers, have a role to play in bringing this bloody business to an end. In this kit, you will find resources that drive this point home to one particular company, Gorton’s of Gloucester, that can make a difference in the fight to save the whales. Gorton’s of Gloucester is wholly owned by Nissui, a Japanese seafood conglomerate and former whaling company that owns one-third of the current Southern Ocean whaling operation. -
Fall Feeding Aggregations of Fin Whales Off Elephant Island (Antarctica)
SC/64/SH9 Fall feeding aggregations of fin whales off Elephant Island (Antarctica) BURKHARDT, ELKE* AND LANFREDI, CATERINA ** * Alfred Wegener Institute for Polar and Marine research, Am Alten Hafen 26, 256678 Bremerhaven, Germany ** Politecnico di Milano, University of Technology, DIIAR Environmental Engineering Division Pza Leonardo da Vinci 32, 20133 Milano, Italy Abstract From 13 March to 09 April 2012 Germany conducted a fisheries survey on board RV Polarstern in the Scotia Sea (Elephant Island - South Shetland Island - Joinville Island area) under the auspices of CCAMLR. During this expedition, ANT-XXVIII/4, an opportunistic marine mammal survey was carried out. Data were collected for 26 days along the externally preset cruise track, resulting in 295 hrs on effort. Within the study area 248 sightings were collected, including three different species of baleen whales, fin whale (Balaenoptera physalus), humpback whale ( Megaptera novaeangliae ), and Antarctic minke whale (Balaenoptera bonaerensis ) and one toothed whale species, killer whale ( Orcinus orca ). More than 62% of the sightings recorded were fin whales (155 sightings) which were mainly related to the Elephant Island area (116 sightings). Usual group sizes of the total fin whale sightings ranged from one to five individuals, also including young animals associated with adults during some encounters. Larger groups of more than 20 whales, and on two occasions more than 100 individuals, were observed as well. These large pods of fin whales were observed feeding in shallow waters (< 300 m) on the north-western shelf off Elephant Island, concordant with large aggregations of Antarctic krill ( Euphausia superba ). This observation suggests that Elephant Island constitutes an important feeding area for fin whales in early austral fall, with possible implications regarding the regulation of (krill) fisheries in this area. -

Whales are complex, often highly social and intelligent creatures. They are mammals like us. They breath air, have hair on their bodies (though only very little), give birth to live young and suckle their calves through mammary glands. But unlike us, whales are perfectly adapted to the marine environment with strong, muscular and streamlined bodies insulated by thick layers of blubber to keep them warm. Whales are gentle animals that have graced the planet for over 50 million years and are present in all oceans of the world. They capture our imagination like few other animals. The largest species of whales were hunted almost to extinction in the last few hundred years and have survived only thanks to conservation and protection efforts. -
