Whistles of bottlenose dolphins (Tursiops truncatus) and Atlantic spotted dolphins (Stenella frontalis) in the eastern Gulf of Mexico were recorded and measured with a calibrated towed hydrophone array. Surveys encountered groups of both bottlenose (N = 10) and spotted dolphins (N = 5).

Teaching is a powerful form of social learning, but there is little systematic evidence that it occurs in species other than humans. Using long-term video archives the foraging behaviors by mother Atlantic spotted dolphins (Stenella frontalis) were observed when their calves were present and when their calves were not present, including in the presence

Echolocation signals of wild Atlantic spotted dolphin (Stenella frontalis)
The Journal of the Acoustical Society of America, 2003An array of four hydrophones arranged in a symmetrical star configuration was used to measure the echolocation signals of the Atlantic spotted dolphin (Stenella frontalis) in the Bahamas. The spacing between the center hydrophone and the other hydrophones was 45.7 cm.

AbstractShark predation risk impacts many facets of dolphin life, including habitat use and foraging strategies. Because direct predation is rarely observed, researchers instead examine dolphins in situ for past injuries that can be attributed to sharks.

Mercury is a metal of toxicological importance that occurs naturally. However, its concentration can be affected by anthropogenic activities and has the potential to bioaccumulate and biomagnify in food webs. Thus, knowing how its concentration varies along the trophic levels allows us to understand its potential risks to the biota.

Whistles emitted by Atlantic spotted dolphins (Stenella frontalis) in southeastern Brazil
The Journal of the Acoustical Society of America, 2010The whistles of Atlantic spotted dolphins have been studied in a few localities of the North Atlantic Ocean and those studies revealed that the species emits whistles within a broad frequency range, with a high number of inflection points and presence of harmonics.

Context specificity of Atlantic spotted dolphin acoustic signals in the Canary Islands
Ethology Ecology & Evolution, 2016The behavioural context provides opportunities for studying the use and characteristics of acoustic signals. We analysed the context-specific use of acoustic signals in a population of Atlantic spotted dolphins around the Canary archipelago. We calculated the whistle diversity, the mean value of whistle stereotypy and the repetition rate of both tonal ...

Cerebral toxoplasmosis in Atlantic spotted dolphin stranded in Canary islands
2023Toxoplasma gondii is a parasitic protozoan species belonging to the Family Sarcocystidae. The life cicle of T.gondii has two phases; a sexual phase, which take placein a definitive host (members of the family Felidae); and an asexual phase, in the intermediate hosts (any warm-blooded animal, including several species of marine mammals).
