Dolphin Longevity and Long‐Term Site Fidelity in the Mississippi Sound: Insights From a 1982 Health Assessment

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Current photo‐ID surveys have identified 10 common bottlenose dolphins that were originally freeze‐branded from a health assessment in the Mississippi Sound from 1982. These dolphins have experienced long‐term site fidelity with confirmed ages being above 30+ years old, and one individual being 47 years old.

The encoding of individual identity in dolphin signature whistles : how much information is needed? [PDF]

, 2013
Bottlenose dolphins (Tursiops truncatus) produce many vocalisations, including whistles that are unique to the individual producing them. Such “signature whistles” play a role in individual recognition and maintaining group integrity.

Genomic Characterization of Aeromonas dhakensis Isolated From a Fatal Dolphin Case

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Comparative genomic analysis of an Aeromonas dhakensis isolate recovered from a fatal dolphin case revealed close relatedness to previously described strains and a broadly comparable virulence‐associated gene profile, including rtxA, with no isolate‐specific virulence‐associated annotations identified.

Chronic interaction between humans and free-ranging bottlenose dolphins near Panama City Beach, Florida [PDF]

, 2004
‘Swim-with’ activities, in which humans enter the water to interact with free-ranging cetaceans, are a popular form of nature tourism; however, there is considerable disagreement as to whether these encounters constitute a threat to the animals.

Behaviourally specific preferred associations in bottlenose dolphins, Tursiops spp. [PDF]

, 2005
We investigated association patterns of 52 photographically identified, free-ranging bottlenose dolphins (Tursiops spp. Gervais, 1855) across four behavioural states (rest, travel, social, and foraging/feeding) to investigate how behavioural state ...

Challenges of collecting blow from small cetaceans

Ecosphere, 2019
We trialed the collection of blow samples using a waterproof electric multirotor (quadcopter) drone from two free‐ranging dolphin species, the abundant and approachable bottlenose dolphin (Tursiops aduncus) and the less common and boat shy humpback ...

Cool‐Water Dolphins Have Larger Appendages Than Warm‐Water Dolphins

Journal of Biogeography, Volume 53, Issue 10, October 2026.
ABSTRACT Aim Endothermic marine mammals face significant thermoregulatory challenges due to heat loss in the highly conductive marine environment. Allen's rule states that endothermic animals in cold environments have smaller appendages than those in warmer environments.

Population dynamics and habitat use of bottlenose dolphins (Tursiops aduncus), Bunbury, Western Australia [PDF]

, 2012
Coastal dolphins are increasingly exposed to a variety of human activities through the proliferation of coastal development. Threats to dolphins in near-shore environments include the loss of suitable habitat, increasing vessel traffic and tourism ...
