The text claims that dolphins are the only mammals whose birth starts with the tail.
Infact verdict: Mixed (48/100).
The claim that dolphins are the only mammals whose birth starts with the tail is not entirely accurate. While dolphins do give birth tail first to prevent drowning, they are not the only mammals to do so. Other marine mammals, such as certain species of whales, also give birth tail first. The evidence suggests that while this birthing method is unique among many mammals, it is not exclusive to dolphins.

The dolphin is the only mammal whose birth starts with the tail.
The claim is misleading. Dolphins do give birth tail first, but they are not the only mammals to do so. Other marine mammals, such as certain whales, also give birth tail first. This is supported by multiple sources, including Whale & Dolphin Conservation USA and Biology Stack Exchange.
