Pulmonary and systemic fungal infections in an Atlantic spotted dolphin and a Bryde’s whale, Brazil [PDF]

Diseases of Aquatic Organisms, 2018
We report the gross and microscopic findings and molecular identification of 2 cases of hyphate fungal infection in cetaceans from Brazil. The first case involved an adult male Atlantic spotted dolphin Stenella frontalis with localized pulmonary disease characterized by pyogranulomatous and necrotizing bronchopneumonia with intralesional hyphae.

Anomalous colouration in an Atlantic spotted dolphin (Stenella frontalis) from southeastern Brazil.

Brazilian Journal of Aquatic Science and Technology, 2013
This note report the first published account of atypical colouration condiction known as pied or piebald for the Atlantic spotted dolphin (Stenella frontalis).  The opportunistic sighting was made at close range between Cabo de São Tomé and Cabo Frio Campos Basin, southeastern Brazil, approximately 60 km offshore.

Contamination status by persistent organic pollutants of the Atlantic spotted dolphin (Stenella frontalis) at the metapopulation level

Environmental Pollution, 2018
The Atlantic spotted dolphin (Stenella frontalis) is an endemic species of the tropical-temperate Atlantic Ocean with widespread distribution. Although this species has been the subject of a large number of studies throughout its range, it remains in the "data deficient" category of the International Union for Conservation of Nature (IUCN).

Hearing loss in stranded odontocete dolphins and whales. [PDF]

PLoS ONE, 2010
The causes of dolphin and whale stranding can often be difficult to determine. Because toothed whales rely on echolocation for orientation and feeding, hearing deficits could lead to stranding.

Detection of Helicobacter in the Digestive Tract of an Atlantic Spotted Dolphin (Stenella frontalis) [PDF]

Journal of Wildlife Diseases, 2010
Helicobacter spp. occur in the digestive system of a broad range of animal taxa, including marine mammals. Only one formally recognized species, Helicobacter cetorum, has been described in marine mammals. Helicobacter has not been reported in the Atlantic spotted dolphin (Stenella frontalis).

The partial merger of two dolphin societies

Royal Society Open Science, 2022
Interactions between mammalian social groups are generally antagonistic as individuals in groups cooperate to defend resources from non-members. Members of the family Delphinidae inhabit a three-dimensional habitat where resource defence is usually ...
