Pink dolphins have long beaks with 24-34 teeth on each side of their jaw. In fact, the neck and jaw of this dolphin is highly specialized to hunt in underwater forests, where they are able to reach through tangled vegetation to extract their prey.
Dolphins have one set of teeth to last their whole lifetime and the number of teeth varies considerably from species to species. The long-beaked common dolphin has more teeth than any other dolphin with up to 240. Risso's dolphins have the fewest; they have between 4 and 14 teeth in their lower jaw only.

Pink dolphins are among the rarest animals on the planet. In 2015, Labroots reported that only about 14 were believed to exist at the time. Also known as Chinese white dolphins, they appear pink when active because increased blood flow and oxygen move closer to the skin as they swim or leap near the surface.

Snails have the most teeth of any animal
A garden snail has about 14,000 teeth while other species can have over 20,000. But that's not even the most shocking part: The teeth of an aquatic snail called the limpet are the strongest known biological material on Earth, even stronger than titanium!

It is sensationalized information that the animals become aggressive towards pregnant individuals - it is simply untrue. Dolphins' echolocation gives them the ability to detect if a woman is pregnant in the water, and the ability to see the baby and heartbeat.
