Global climate change during the Late Pleistocene periodically encroached and then released habitat glacial cycles, causing range expansions contractions in some species. These dynamics have played a major role geographic radiations, diversification speciation. We investigate these most widely distributed of marine mammals, killer whale (Orcinus orca), using global data set over 450 samples. This top predator inhabits coastal pelagic ecosystems ranging from ice edge to tropics, often...
Eurasian otters ( Lutra lutra ) are mammals found in waterways and coastal areas of Europe, parts Asia, northern Africa, where they inhabit aquatic environments with adequate food resources, primarily fish. This descriptive study aimed to investigate describe the macromorphology, microstructure, mechanical properties, elemental composition teeth two subadult otters. A total six teeth, comprised upper incisors, canines, one premolar, molar tooth were analyzed. Teeth measured, photographed,...
Abstract In the Caribbean Sea, orcas ( Orcinus orca , also known as killer whales) are present throughout year. The most recent review confirmed seven strandings of species in Sea period May 1851 to January 2023, all which were single and only one occurred Venezuela. this publication we document circumstances successful rescue, by local fishers authorities, that stranded August 2023 on coast State Sucre, north-eastern Worldwide, is second mass stranding within tropics (23.5°N 23.5°S). We...
Abstract On a global scale, false killer whales ( Pseudorca crassidens ) remain one of the lesser‐known delphinids. The occurrence, site fidelity, association patterns, and presence/absence foraging in waters off northeastern New Zealand are examined from records collected between 1995 2012. species was rarely encountered; however, 61 distinctive, photo‐identified individuals, 88.5% were resighted, with resightings up to 7 yr after initial identification, movements as far 650 km documented....
The first record of killer whale (Orcinus orca) predation on false whales (Pseudorca crassidens) is reported here. On 25 March 2010, a group 50 to 60 whales, including approximately 15 calves and accompanied by three five bottlenose dolphins (Tursiops sp.), were sighted in the Bay Islands, New Zealand. Within 30 min, they approached eight whales. Five attacked, with at least rammed from below, forcing them out water. After 29 milling surface feeding carcass calf, possibly only individual...
Abstract Two orca (Orcinus orca, Linnaeus, 1758), photo‐identified as part of an ongoing study in New Zealand waters, have a series deep scars their dorsal lumbar‐caudal regions which suggests they were caused by propellers. One the animals, first noted to 1982, is considerably smaller than adult similar age. The known home range these are presented. A third hit boat presumed dead.
In contrast to previous reports that leopard seals (Hydrurga leptonyx) are rare vagrants New Zealand, we show this species is a regular member of the marine fauna region. We present first analysis from Zealand Leopard Seal Database – an extensive collation 2,711 records within between 1200 and 2018. Of these records, 51.2% (n = 1,408) were photographic. seal sightings have increased over time been reported in all seasons regions Zealand. Sightings predominantly adult individuals good or...
Killer whale (Orcinus orca) predation on elasmobranchs (sharks and rays) is not often reported. In New Zealand waters, killer whales captured ate thresher (Alopias vulpinus) smooth-hammerhead (Sphyrna zygaena) sharks. Both species were reported previously as prey of whales. These observations help support the idea that are a main type for whales; ten now recorded this population.
Anomalous pigmentations have been recorded in many cetacean species. However, typically only one variation is reported from a population at time (e.g., an albino). Here we record spectrum of pigmentation common dolphins (Delphinus sp.) off northern New Zealand. Allblack, dark-morph, pale-morph, and all-white individuals, as well variations between these recorded. Pale-coloured pectoral flippers are prevalent, number individuals with white “helmets” observed.
We collated (n=36) records of orca (Orcinus Linnaeus, 1758, also known as the killer whale (Cetacea Delphinidae) in waters Republic Fiji, South Pacific Ocean. Using standardised criteria, we classified these into Confirmed, Presumed and Unconfirmed. then conflated replicated to create (n=12) unique meta-records between 1994-2024. confirm, for first time with photographs/video, species present Fijian evidence (photos/video) (n=6) 2006–2024 which illustrate species-specific characteristics....
Ocean sunfish (Mola spp.) are well known for their large adult size and peculiar morphology, which in combination give them the resemblance of a giant, swimming fish head.At first glance, this unusual body form hints at locomotive ineptitude, traditionally molids have indeed been considered poor swimmers.Although archaic view has thoroughly rebutted recent years, with studies revealing strong swimmers (for example ability to rapidly accelerate, recorded burst speeds Mola mola 6.6 m/s),...
Abstract Reports of anomalously pigmented cetaceans, including melanistic (all‐black) individuals are infrequent. We observed four southern right‐whale dolphins (Lissodelphis peronii) a calf, off Kaikoura (42°34'S, 173°50'E), New Zealand. also compiled records from five other species cetaceans. The ecological context pigmentation cetaceans is not well understood; however, it may increase heat absorption, affect ability to capture prey, impair visual/social communication, and/or...
