Mating, Sociosexual, and Nursing Behavior of Wild East Asian Finless Porpoises in the Seto Inland Sea, Japan

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT The mating and sociosexual (nonconceptive) behaviors of narrow‐ridged finless porpoises (Neophocaena asiaeorientalis) have been extensively studied in captivity. However, such behaviors may differ significantly from those that have developed in wild populations. Drone videos captured the behaviors of wild finless porpoises including a total of

Aerial Photo-Identification of Sperm Whales (Physeter macrocephalus)

Aquatic Mammals
Photo-identification is a staple tool used in cetacean conservation studies since the 1970s to monitor individuals on a regional and ocean basin-wide scale to infer critical information about habitat use, suitability, and shifts. This technique has been extensively used on sperm whales globally since it was developed in 1982, initially using the tail ...
