Molecular studies on two variant repeat types of the common cetacean DNA satellite of the sperm whale, and the relationship between Physeteridae (sperm whales) and Ziphiidae (beaked whales). [PDF]

Molecular Biology and Evolution, 1993
In the sperm whale (Physeter macrocephalus) two different repeat types (A and B) of the common cetacean DNA satellite were identified. The evolution of each group of repeats appears to be independent from that of the other. The sequence similarity between the two groups is less than the similarity between group A and repeats of the satellite in related

μCeta: A Set of Cetacean‐Specific Primers for Environmental DNA Metabarcoding With Minimal Amplification of Non‐Target Vertebrates

Environmental DNA, Volume 7, Issue 5, September–October 2025.
Cetacean eDNA metabarcoding results from the aquarium pool samples using new cetacean‐specific primers. μCeta shows superior performance to detect and differentiate different cetacean species. ABSTRACT Biodiversity monitoring is crucial for understanding ecosystem dynamics and species distributions, particularly in the context of anthropogenic impacts ...

A novel trypanoplasm-like flagellate Jarrellia atramenti n. g., n. sp. (Kinetoplastida: Bodonidae) and ciliates from the blowhole of a stranded pygmy sperm whale Kogia breviceps (Physeteridae): morphology, life cycle and potential pathogenicity [PDF]

Diseases of Aquatic Organisms, 2001
The successful 6 mo rehabilitation of a stranded juvenile pygmy sperm whale Kogia breviceps afforded the opportunity to study the poorly known protozoan fauna of the upper respiratory tract of cetaceans. Mucus samples were collected by holding either a petri dish or glass slides over the blowhole for 3 to 5 exhalations; preparations were examined as ...

Prioritizing future evidence needs for marine and freshwater mammal conservation action

Animal Conservation, Volume 28, Issue 4, Page 542-552, August 2025.
To improve conservation practice, decisions should be informed by the available evidence on the effectiveness of conservation actions. Here, we review the comprehensiveness of this evidence base for marine and freshwater mammals. We assess the taxonomic and geographic coverage of the evidence base, identify biases and suggest priorities for future ...
