Adaptation to the marine environment These animals have colonized a wide range of aquatic ecosystems, as the freshwater species located in the watercourses of some rivers (Amazon, Indo, Ganges and the Yellow River); and many other marine species distributed in the estuaries, shallow-water coves, continental coasts and the open sea. These ones show a cosmopolitan distribution in the seas and oceans, and the other ones are located only in certain areas. Social behaviour · Strong association. They do prefer to associate with other cetacean species. · They can recognise each other after a long-term separation. · Long-lasting bonds are present between the mother and the young. · They help each other in case of sickness or blessures. · They are capable of recognising themselves in front of the mirror. · Sex is important either to solve conflicts among them, either to experience pleasure. · They are able to learn the language of symbols. ·They have different personalities.

  • Subsurface and Nighttime Behaviour of Pantropical Spotted Dolphins in Hawai′I
    Color profile: Generic CMYK printer profile Composite Default screen 988 Subsurface and nighttime behaviour of pantropical spotted dolphins in Hawai′i Robin W. Baird, Allan D. Ligon, Sascha K. Hooker, and Antoinette M. Gorgone Abstract: Pantropical spotted dolphins (Stenella attenuata) are found in both pelagic waters and around oceanic is- lands. A variety of differences exist between populations in these types of areas, including average group sizes, extent of movements, and frequency of multi-species associations. Diving and nighttime behaviour of pantropical spotted dolphins were studied near the islands of Maui and Lana′i, Hawai′i, in 1999. Suction-cup-attached time–depth recorder/VHF-radio tags were deployed on six dolphins for a total of 29 h. Rates of movements of tagged dolphins were substantially lower than reported in pelagic waters. Average diving depths and durations were shallower and shorter than reported for other similar-sized odontocetes but were similar to those reported in a study of pantropical spotted dolphins in the pelagic waters of the eastern tropical Pacific. Dives (defined as >5 m deep) at night were deeper (mean = 57.0 m, SD = 23.5 m, n = 2 individuals, maximum depth 213 m) than during the day (mean = 12.8 m, SD = 2.1 m, n = 4 individuals, maximum depth 122 m), and swim velocity also increased after dark. These results, together with the series of deep dives recorded immediately after sunset, suggest that pantropical spotted dolphins around Hawai′i feed primarily at night on organisms associated with the deep-scattering layer as it rises up to the surface after dark.

Ensenada, Baja California, México 22860 Abstract Although many studies confirm long-term small isolated populations (e.g. island endemics) commonly sustain low neutral genetic variation as a result of genetic drift, it is less clear how selection on adaptive or detrimental genes interplay with random forces. We investi- gated sequence variation at two major histocompatibility complex (Mhc) class II loci on a porpoise endemic to the upper Gulf of California, México (Phocoena sinus, or vaquita). Its unique declining population is estimated around 500 individuals. Single-strand confor- mation polymorphism analysis revealed one putative functional allele fixed at the locus DQB (n = 25). At the DRB locus, we found two presumed functional alleles (n = 29), differ- ing by a single nonsynonymous nucleotide substitution that could increase the stability at the dimer interface of αβ-heterodimers on heterozygous individuals.

  • Sea Watch Foundation – Northern Bottlenose Whale in UK Waters
    SPECIES INFORMATION SHEET NORTHERN BOTTLENOSE WHALE IN UK WATERS DESCRIPTION The northern bottlenose whale, Hyperoodon ampullatus, is probably the best- studied species within the beaked whale family, Ziphiidae. Males are from 8.5-9.8 metres and females 7.5-8.7 metres in length. The most distinctive feature of the species is the bulbous forehead (particularly pronounced in adult males) and its relatively short, dolphin-like beak. There are two teeth at the tip of the lower jaw, which only erupt in adult males. The dorsal fin is relatively tall and sickle-shaped, and situated nearly two-thirds of the way along the back. As in other beaked whales, the tail flukes lack a central notch. The body colour is chocolate brown, to yellowish (depending on whether there is a growth of diatoms over the skin), and adult males have a white patch on the forehead. At sea, the blow is bushy, about 2 metres high, and slightly forward-pointing. DISTRIBUTION AND STATUS The range of the northern bottlenose whale is restricted to the North Atlantic, where it occurs mainly in cold temperate and sub-arctic waters. The species favours deep ocean trenches, such as occur off Newfoundland (particularly “the Gully”), western Norway, and in the Barents Sea. Its migration pattern is more complex than a mere north-south movement, and some populations seem to be resident year-round. The distribution seems to be strongly influenced by that of its major prey - squid of the genus Gonatus. Northern bottlenose whales are found mainly in deep waters of greater than 1,000 m depth, often over submarine canyons and adjacent to the continental shelf edge, although they sometimes enter more shallow waters (300 m or less depth), and in January 2006, one even found its way up the river Thames to the city of London! In waters adjacent to the UK and Ireland, the species is sighted primarily in the Faroe-Shetland Channel, Rockall Trough, and southern Bay of Biscay, but it has been seen on occasions in coastal waters, for example around the Isle of Skye or off Northern Scotland.

  • Population Analysis of Endangered Northern Bottlenose Whales on the Scotian Shelf Seven Years After the Establishment of a Marine Protected Area
    Vol. 21: 273–284, 2013 ENDANGERED SPECIES RESEARCH Published online October 9 doi: 10.3354/esr00533 Endang Species Res Population analysis of Endangered northern bottlenose whales on the Scotian Shelf seven years after the establishment of a Marine Protected Area Kristin O’Brien*, Hal Whitehead Department of Biology, Dalhousie University, Halifax, Nova Scotia B3H 4J1, Canada ABSTRACT: Marine Protected Areas (MPAs) are being established worldwide to protect vulnera- ble marine species and habitats, in the face of accelerating rates of species extinctions. Biophysical indicators such as focal species abundance are often employed to assess the effectiveness of MPAs at meeting conservation objectives. We examined the dynamics of an Endangered beaked whale population 7 yr after the Gully MPA was established in 2004 off Nova Scotia, Canada. Northern bottlenose whales forage in deep water such as the Gully submarine canyon. Several MPA restric- tions were implemented on the Gully ecosystem beginning in 2004 to reduce anthropogenic impacts including ship traffic, underwater noise and entanglements. This study represents the first intensive northern bottlenose whale population assessment since the Gully became a MPA. Using photo-identification data collected in 2010 and 2011, we applied mark–recapture tech- niques to estimate the current population size of northern bottlenose whales on the Scotian Shelf as 143 animals (95% CI: 129 to 156 animals). We also used open population models to examine population trends, and investigated changes in the sex ratio since 1988. Our results suggest the population size and sex ratio have been stable since before MPA legislation was implemented, illustrating the resilience of this population and suggesting that the MPA objective of preventing population decline is being met.

    CETACEAN ABUNDANCE IN HAWAIIAN WATERS DURING SUMMER/FALL OF 2002 Jay Barlow Southwest Fisheries Science Center 8604 La Jolla Shores Dr. La Jolla, CA 92037 ABSTRACT The abundance of cetaceans is estimated for the U.S. Exclusive Economic Zone (EEZ) around the Hawaiian Islands based on a survey in August-November 2002. Two NOAA research vessels were used for this line-transect survey. Sighting detection functions were estimated from this and other NOAA research surveys from 1986 to 2002 using a new, multiple-covariate approach. Twenty four species were seen on this survey, including two species (Fraser’s dolphin - Lagenodelphis hosei and sei whale - Balaenoptera borealis) that had not been previously documented to occur in Hawaiian waters. The most abundant large whales were sperm whales (Physeter macrocephalus) and Bryde’s whales (Balaenoptera edeni). The most abundant delphinids were rough-toothed dolphins (Steno bredanensis) and Fraser’s dolphins (Lagenodelphis hosei). Dwarf and pygmy sperm whales (Kogia simus and K. breviceps) and Cuvier’s beaked whales (Ziphius cavirostris) were estimated to be quite abundant. Some of the migratory baleen whales (fin whales - Balaenoptera physalus, sei whales, minke whales - B. acutorostrata, and humpback whales - Megaptera novaeangliae) were seen only late in the survey. Abundance could be estimated for 21 cetacean species, but the estimated abundances of migrating whales do not correspond to their period of highest abundance in this area. The overall density of cetaceans was low in the study area, especially for delphinids. The precision of density and abundance estimates was generally low for all species due to the small number of sightings.
