Duration of unassisted swimming activity for spotted dolphin (Stenella attenuata) calves: implications for mother-calf separation during tuna purse-seine sets [PDF]

open access: yes, 2006
Size-related differences in power production and swim speed duration may contribute to the observed deficit of nursing calves in relation to lactating females killed in sets by tuna purse-seiners in the eastern tropical Pacific Ocean (ETP).

Comparative Analysis of the Whistles of Three Oceanic Dolphins in the Comoros

open access: yesMarine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT The Shisiwani National Park (Anjouan, Comoros) is a cetacean biodiversity hotspot. However, the vocal behavior of marine mammals inhabiting the area has never been studied. In 2023, we conducted a 400‐nautical‐mile survey from a 5‐m motorboat to determine their presence.

Influence of environmental variability on the distribution and abundance of the pantropical spotted dolphin (Stenella attenuata) in the Mexican Central Pacific

open access: yesCiencias Marinas, 2022
The Mexican Central Pacific (MCP) has complex oceanographic dynamics, with a well-defined seasonal pattern and influence of interannual sea surface temperature anomalies. The present study investigated the relationship between the distribution/abundance

Melon‐Headed Whale (Peponocephala electra) Occurrence in the Equatorial Mid‐Atlantic Ocean With Descriptions of Their Whistles

open access: yesMarine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Acoustic studies for any cetacean species in tropical Atlantic Ocean waters are scarce, especially for oceanic dolphins, such as the melon‐headed whale, Peponocephala electra. Here we describe a unique visual and acoustic record for this species, filling an information gap about the acoustic patterns of these delphinids in this part of the ...

Feeding Ecology of Elusive Caribbean Killer Whales Inferred From Bayesian Stable Isotope Mixing Models and Whalers’ Ecological Knowledge

open access: yesFrontiers in Marine Science, 2021
Investigating the feeding ecology of marine predators is critical for understanding their roles and functional importance in ecosystems. However, assessing the diet of large and wide-ranging predators can be challenging, particularly in the case of rare ...

A Detailed Characterization of the Whistle Repertoire of Fraser's Dolphins (Lagenodelphis hosei) From the Lesser Antilles

open access: yesMarine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Fraser's dolphin (Lagenodelphis hosei) remains poorly studied due to its elusive behavior, rarity, and preference for deep offshore habitats. While dolphins use frequency‐modulated whistles for communication, detailed acoustic descriptions exist for only a few species.

Seasonal and Multidecadal Changes in the Distribution of Small Cetaceans Inhabiting the Western North Pacific Under a Changing Ocean Environment, Inferred From Species Distribution Models

open access: yesDiversity and Distributions, Volume 31, Issue 12, December 2025.
ABSTRACT Aim For several decades, substantial efforts have monitored cetacean distribution and abundance in the western North Pacific. Large‐scale visual‐based line transect surveys have been conducted since the early 1980s, covering almost the entire western North Pacific.
