What Makes the Spade-Toothed Whale One of the Rarest and Most Intriguing Cetaceans?

The reproductive habits of spade-toothed whales are still largely a mystery. However, it is believed that they have a long gestation period, possibly lasting up to 12 months, similar to other beaked whales. The lifespan of these whales is also uncertain, but estimates suggest they could live for several decades, making them long-lived members of the marine ecosystem.
