True’s beaked whale (Mesoplodon mirus) in Macaronesia [PDF]

PeerJ, 2017
The True’s beaked whale (Mesoplodon mirus, True 1913) is a poorly known member of the Ziphiidae family. Its distribution in the northern hemisphere is thought to be restricted to the temperate or warm temperate waters of the North Atlantic, while a few ...

Abundance and densities of beaked and bottlenose whales (family Ziphiidae)

J. Cetacean Res. Manage., 2023
Estimating the abundance and density of beaked whales is more difficult than for most other cetacean species. Consequently few estimates appear in the published literature. Field identification is problematic, especially for the smaller species, and visual detection rates decrease dramatically with Beaufort sea state; prior experience is very important

Known and inferred distributions of beaked whale species (Cetacea: Ziphiidae)

J. Cetacean Res. Manage., 2023
Information regarding beaked whales is so sparse that even the most basic aspects of their biology, such as their distribution, remain poorly defined for some species. We have reviewed the known distribution of each beaked whale species and where possible, used this information to infer its global distribution.

Complete mitochondrial genomes and phylogeny of two rare whale species: True’s (Mesoplodon mirus: True 1913) and Sowerby’s (Mesoplodon bidens: Sowerby 1804) beaked whales

Mitochondrial DNA. Part B. Resources, 2019
Beaked whales of the genus Mesoplodon are rarely encountered and information on their basic biology is lacking. We sequenced the complete mitochondrial genomes of True’s (Mesoplodon mirus) and Sowerby’s (Mesoplodon bidens) beaked whales to high depth ...

Biogeography in the deep: Hierarchical population genomic structure of two beaked whale species

Global Ecology and Conservation, 2022
The deep sea is the largest ecosystem on Earth, yet little is known about the processes driving patterns of genetic diversity in its inhabitants. Here, we investigated the macro- and microevolutionary processes shaping genomic population structure and ...

First records of Mesoplodon europaeus (Gervais, 1855), Gervais’ Beaked Whale (Cetacea, Ziphiidae, Mesoplodon), and other beaked whales in Suriname, South America [PDF]

Check List, 2023
A group of Mesoplodon europaeus (Gervais, 1885), Gervais’ Beaked Whales, were recorded along the Demerara Plateau (Suriname) at depths of 2,300 and 2,700 m.  These are the first records of the species within the Guiana Basin.

A new Beneziphius beaked whale from the ocean floor off Galicia, Spain and biostratigraphic reassessment of the type species [PDF]

Acta Palaeontologica Polonica, 2017
Although the fossil record of beaked whales (Cetacea, Odontoceti, Ziphiidae) is continuously improving, the geological age of new taxa is often poorly constrained.

The oldest fossil record of the extant genus Berardius (Odontoceti, Ziphiidae) from the Middle to Late Miocene boundary of the western North Pacific [PDF]

Royal Society Open Science, 2021
A new species of a beaked whale that belongs to the extant genus Berardius is described from the Middle to Late Miocene boundary age Tsurushi Formation (ca 12.3–11.5 Ma) on the Sado Island, Niigata Prefecture, Japan. The new species, Berardius kobayashii

KOGIA PUSILLA FROM THE MIDDLE PLIOCENE OF TUSCANY (ITALY) AND A PHYLOGENETIC ANALYSIS OF THE FAMILY KOGIIDAE (ODONTOCETI, CETACEA)

Rivista Italiana di Paleontologia e Stratigrafia, 1999
A partial skull of an odontocete cetacean from Middle Pliocene sediments of Monte Voltraio (Pisa Province, Tuscany, Italy) is examined. This fossil, erroneously referred to the family Ziphiidae and described in the past as holotype of the species ...
