Marine 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 kinematic study on (un)intentional imitation in bottlenose dolphins [PDF]
, 2015 The aim of the present study was to investigate the effect of observing other's movements on subsequent performance in bottlenose dolphins. The imitative ability of non-human animals has intrigued a number of researchers.

Marine Mammal Science, Volume 42, Issue 2, April 2026.ABSTRACT Most extant beaked whales have reduced dentition of one or two pairs of tusk‐like, mandibular teeth that erupt through the gum only in adult males. Additional teeth have been recorded in several species and genera. A juvenile Hector's beaked whale (SAMA M26434) having additional teeth was collected in South Australia and its skeleton and ...

Conceptive Estrus Behavior in Three Bottlenose Dolphins (Tursiops truncatus) [PDF]
Animal Behavior and Cognition, 2015 Bottlenose dolphins (Tursiops truncatus) are a highly promiscuous species that routinely engage in socio-sexual interactions, yet relatively little has been reported about actual estrus behavior.

Ecology and Evolution, Volume 16, Issue 3, March 2026.We applied eDNA metabarcoding to assess vertebrate diversity in the Rance Estuary, France, across five stations spanning marine to freshwater environments, including areas upstream and downstream of a tidal power plant dam. A total of 124 vertebrate MOTUs were detected, with community composition reflecting the estuarine gradient and species turnover ...

Epidermal Growth in the Bottlenose Dolphin, Tursiops truncatus
Journal of Investigative Dermatology, 1985 Epidermal growth in two mature female bottlenose dolphins, Tursiops truncatus, was investigated by following the movement of a cohort of tritiated thymidine-labeled epidermal cells for 59 days. The majority of the cells migrated in a cluster which was estimated to reach the skin surface in 73 days. We calculate that the outermost cell layer is sloughed

Spermatozoa of the Atlantic bottlenosed dolphin, Tursiops truncatus [PDF]
Reproduction, 1981 Semen from a male dolphin in captivity was collected by electro-ejaculation and frozen to -176 degrees C. Sperm motility was excellent after thawing 10 days later. Electron microscopy showed 14-16 parallel ridges in the post-acrosomal region and two types of mitochondria in the mid-piece.

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.To effectively mitigate disturbances from human activities on vulnerable dolphin populations, it is crucial to understand fine‐scale variation in habitat use. This study investigated the habitat utilisation of a small subpopulation of Hector's dolphins (Cephalorhynchus hectori) in Porpoise Bay, New Zealand.
