Tagging Very Small Fish: Two Effective and Low Impact Methods

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 3, Page 213-224, April 2026.
ABSTRACT Identifying individuals over time and across contexts is essential in many scientific fields. There are a variety of well‐established methods for uniquely marking individuals (e.g., visible implant elastomer, barcodes, paint). However, for some species, life history stages, and/or experiments, existing methods are not sufficient.

Marine flora and fauna of the eastern United States Mollusca: Cephalopoda [PDF]

open access: yes, 1989
The cephalopods found in neritic waters of the northeastern United States include myopsid and oegopsid squids, sepiolid squids, and octopods. A key with diagnostic illustrations is provided to aid in identification of the eleven species common in the ...

Timing is everything: Drivers of interannual variability in blue whale migration. [PDF]

open access: yes, 2020
Blue whales need to time their migration from their breeding grounds to their feeding grounds to avoid missing peak prey abundances, but the cues they use for this are unknown.

Geographical and Seasonal Distribution of Australian Pygmy Right Whales (Caperea marginata) Based on Passive Acoustics

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT The pygmy right whale (Caperea marginata) is one of the least studied mysticete species. To shed light on its geographic and seasonal distribution, we compiled archival acoustic recordings from 26 sites across southern Australia and developed a deep‐learning detector for pygmy right whale “doublet” vocalizations.

Humpback and Fin Whaling in the Gulf of Maine from 1800 to 1918 [PDF]

open access: yes, 2002
The history of whaling in the Gulf of Maine was reviewed primarily to estimate removals of humpback whales, Megaptera novaeangliae, especially during the 19th century.

Increasing Efficiency of Detection and Validation of Baleen Whale Call Presence on Large Acoustic Datasets: A Case Study Using Sei Whale Downsweeps Recorded in Atlantic Canada

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT As passive acoustic monitoring (PAM) datasets expand, studies increasingly use automated detectors to analyze baleen whale presence. However, detector errors like false positives (impacting precision, P; proportion of detected calls that are correct), and false negatives (impacting recall, R; proportion of available calls successfully detected)

What do humpback whales Megaptera novaeangliae (Cetartiodactyla: Balaenopteridae) pairs do after tagging?

open access: yesZoologia (Curitiba), 2014
The social structure of humpback whales in their tropical wintering grounds is very fluid. To date, no information has been published for cases in which two whales were both satellite-tagged while in association.

Unveiling Patterns in Cetacean Strandings Along Southern Atlantic Iberia: Temporal and Spatial Trends, Seasonality, and Causes of Death

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT We compiled 46 years of cetacean strandings in the Algarve, Portugal, describing temporal–spatial patterns, size–sex structure, and causes of death (COD). We analyzed national records and years with a dedicated regional stranding network (SN) to assess annual/seasonal trends, spatial hotspots, and compare biometrics and COD.

A Note on Suckling Behavior and Laterality in Nursing Humpback Whale Calves from Underwater Observations

open access: yesAnimals, 2017
We investigated nursing behavior on the Hawaiian breeding grounds for first year humpback whale (Megaptera novaeangliae) calves. We observed and video-documented underwater events with nursing behavior from five different whale groups.
