条纹原海豚 tiáo wén yuán hǎi tún Stenella coeruleoalba

条纹原海豚（学名：Stenella coeruleoalba）海豚科原海豚属的一种物种，喙中等长。体稍粗，具蓝色和白色的色斑，背侧的披肩蓝色或蓝灰色，有1条白色至浅灰色的脊斑从胁部插人披肩伸展到背鳍下方（类手指状图案）。背鳍镰刀形。腹部白色至粉红色。

Stenella coeruleoalba is a species of the family Dolphinidae, genus Dolphinidae, with an equal length in the beak. Slightly thick, with blue and white spots, the back of the shawl is blue or bluish gray, and there is a white to light gray ridge that extends from the flank into the shawl to below the dorsal fin (similar to a finger like pattern). The dorsal fin is sickle shaped. The abdomen is white to pink.

条纹原海豚能做多种空中动作，如跃水、撞水等。有一种它们特有的行为，称为“转尾”，高高跃起，在人水前快速转动尾叶。

该种数量原本非常丰富，为太平洋常见海豚，近年来由于生态环境日益恶化，种群数目急剧下降，亟待保护。
