'''Delfin uzdeczkowy, d. plamisty, d. plamisty atlantycki''' (''Stenella frontalis'') – waleń z rodziny delfinów oceanicznych.

Często spotykany atlantycki delfin, którego pożywieniem są różnorodne głowonogi i ryby. W niektórych miejscach jest nawet pospolity. Czasami łowi się je przypadkowo w niewody razem z tuńczykami, ginie w ten sposób duża część stada.
 
Delfin uzdeczkowy lubi pływać z ludźmi, nawet czasem zwalnia, żeby człowiek mógł za nim nadążyć, jest bardzo towarzyski, o czym świadczy fakt, że w jego stadach często zauważa się przedstawicieli innych gatunków.
 
Jego kształt, zwłaszcza głowa, przypomina wyglądem butlonosa i, pomimo że jest od niego dużo mniejszy, bywają ze sobą mylone.
Delfin uzdeczkowy jest czarno-biały, z białymi plamkami na grzbiecie i czarnymi na brzuchu. Największy dotąd zmierzony okaz, samica,
mierzyła 2,29 m i ważyła 140 kg.

The '''Atlantic Spotted Dolphin''' (''Stenella frontalis'') is a dolphin found in the Gulf Stream of the North Atlantic Ocean. Older members of the species have a very distinctive spotted coloration all over their body.

==Taxonomy==
The Atlantic Spotted Dolphin was first identified by Cuvier in 1828. There is considerable variation in the physical form of individuals in the species and specialists have long been uncertain as to the correct taxonomic classification. Currently just one species is recognised, however it is quite possible that a large, particularly spotty variant commonly found near Florida may be classified as a formal subspecies or indeed a species in its own right.

==Physical description==
The coloring of the Atlantic Spotted Dolphin varies enormously as they grow.
Calves are a fairly uniform grey colour. When the calves are weaned, they then begin to get their spots. Juveniles have some dark spots on their belly, and white spots of their flanks. Their back and dorsal fin are a darker grey than the rest of the body. As the animal matures the spots became denser and spread all over the body until at full physical maturation the body appears black with white spots.

The Atlantic Spotted Dolphin has a 3-part coloration:
:Dark gray back, lighter sides, and a white belly.

Measurements at Birth:
:Length: about 35"-43" (90-110 cm)
:Weight: unavailable 

Maximum Measurments:
:Length:
::Male  7'5" (2.26 m)
::Female  7'6" (2.29 m)
:Weight:
::Male  310 lb. (140 kg)
::Female 290 lb. (130 kg)

These dolphins are a middle sized dolphin in both length and weight.
At full size South American Spotted Dolphins are about 2.2-2.5m in length. Compared to their much smaller pantropical spotted dolphin, the Atlantic spotted dolphin is more robust. It lives in common waters with the pantropical spotted dolphin and the bottlenose dolphin.

In common with other species in its genus the Atlantic Spotted is a gregarious creature. It is a fast swimmer, keen bow-rider and prone to acrobatic aerial displays.
