The red pipefish (Notiocampus ruber) is a rare relative of seahorses and seadragons found only in Australia.

While pipefishes and seahorses are famous for male pregnancy, the family is split by how the males carry their young. Many pipefish—and all seahorses—are “tail brooders,” carrying eggs on the tail in pouches.

Another group of pipefish, the “trunk brooders,” carry eggs exposed directly on the belly.
