Histological aspects of the mucosa of the spermaceti chamber of a dwarf sperm whale

Brazilian Journal of Veterinary Research and Animal Science, 2017
O sistema de produção sonora do cachalote-anão (Kogia sima) apresenta uma complexa estrutura anatômica composta por melão, espermacete, lábios fônicos, “vocal cap”, “case”, papilas, câmara do espermacete e outros espaços aéreos, além de músculos faciais envolvidos na produção sonora.

Bubble blasts! An adaptation for buoyancy regulation in shallow foraging gray whales. [PDF]

Ecol Evol
Gray whales use bubble blasts (underwater exhalations) to regulate their buoyancy while feeding in shallow habitats. Pacific Coast Feeding Group gray whales feed in shallow coastal habitats using a variety of behaviors. Using a 7‐year dataset of drone footage, we show that longer and more buoyant whales use bubble blasts to extend their dive duration ...

Morphological and morphometric sperm analysis of dwarf sperm whale (Kogia sima)

Acta Scientiarum. Biological Sciences
Nowadays, an increase in the number of marine species at risk of extinction has been observed. Therefore, studies on the reproductive characteristics of these animals are essential. This animal is considered relatively rare, and there is scarce information regarding its reproductive biology and physiology.

Occurrence and Whistle Characteristics of Small Odontocetes in Two Coastal Regions of the Sea of Japan

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT This study investigated the occurrence and whistle characteristics of small odontocetes in Wakasa Bay and Aso Bay, located in the coastal waters of the Sea of Japan, where ecological data are limited. Passive acoustic monitoring using A‐tag and SoundTrap was conducted from 2022 to 2024, with detections on 8.8% and 12.4% of monitoring days at ...

Seeing Through the “Clouds” With Molecular “Eyes”. First eDNA‐Based Detections of Pygmy Sperm Whale (Kogia breviceps) in the Mediterranean Sea

Mammal Review, Volume 56, Issue 1, March 2026.
For the first time, environmental DNA (eDNA) from the Mediterranean Sea reveals the cryptic presence of the pygmy sperm whale (Kogia breviceps). Analysis of 393 samples detected repeated, spatiotemporally structured molecular signals, suggesting a resident population.

High diversity and unique composition of gut microbiomes in pygmy (Kogia breviceps) and dwarf (K. sima) sperm whales [PDF]

Scientific Reports, 2017
AbstractMammals host diverse bacterial and archaeal symbiont communities (i.e. microbiomes) that play important roles in digestive and immune system functioning, yet cetacean microbiomes remain largely unexplored, in part due to sample collection difficulties.

Environmental DNA (eDNA) Technology in Biodiversity and Ecosystem Health Research: Advances and Prospects

Ecology and Evolution, Volume 16, Issue 1, January 2026.
This review synthesizes over 15 years of advancements in eDNA technology by systematizing standardized guidelines for sampling, extraction, and bioinformatics, thereby enhancing the reproducibility of eDNA‐based research. It highlights eDNA's transformative role in noninvasively detecting rare, endangered, and invasive species, as well as its value in ...
