About this species
The pantropical spotted dolphin (Stenella attenuata) is a species of dolphin found in all the world's temperate and tropical oceans. The species was beginning to come under threat due to the killing of millions of individuals in tuna purse seines. In the 1980s, the rise of "dolphin-friendly" tuna capture methods saved millions of the species in the eastern Pacific Ocean and it is now one of the most abundant dolphin species in the world.

热带斑海豚约 10-12 岁成熟，平均寿命约 40 岁。成体全长 1.66-2.57 m，体重 100-120 kg，雄性比雌性略大。具有流线形的躯干与镰刀状的背鳍，背鳍下方有一片深灰色区域，腹部为浅灰色。成年个体吻部尖端呈白色，身上布满斑点。初生幼体无斑点，随着年龄增长斑点开始出现，背部的斑点颜色较浅而腹部的较深，至成年时腹部斑点颜色由深转浅；斑点随年龄增长而不断增多，有些老年个体甚至斑点多到无法辨识表皮的底色。
热带斑海豚喜欢成群活动，有时会接近船只乘浪跳跃，性情相当活泼。游速很快，可达 22 km/h。通常栖息在水深 50 m 以内的浅海，较少潜入深水区。
