Haborophocaena (SciiFii)

The giant porpoise (Haborophocaena giganteum), also known as the titan porpoise or the giant vaquita, is a species of porpoise that originally lived during the Pliocene as an extinct species, Haborophocaena toyoshimai, and was once extinct, but has since been brought back from extinction by SciiFii and introduced throughout the modern world's oceans to help boost biodiversity. The giant porpoise, as its name suggests, is the world's largest species of porpoise, reaching seven meters long on average, being comparable to the killer whale in size, and far bigger than other porpoises, one of which, the vaquita, is among the smallest living cetaceans. Giant porpoises are opportunistic, hunting a variety of surface and mid-water species. Common prey are mesopelgic fish, such as myctophids, and gonatid squid. Stomach content analyses have also found cases of crustacean consumption, including krill and shrimp, but this is abnormal and likely not an important part of their diet. Like many other porpoises, the giant porpoises are social animal, usually living in pods of around 2 – 10 individuals, but aggregations of hundreds have been reported. Giant porpoises are highly active swimmers. Rapid swimming at the surface creates a characteristic spray called a "rooster tail". They are commonly seen approaching boats to bowride, and they will also ride on the waves formed at the heads of larger swimming whales. Giant porpoises mate promiscuously. Males produce large amounts of sperm, perhaps for sperm competition. Females become sexually mature by their third or fourth year and can calve each year for several consecutive years, being pregnant and lactating at the same time. The gestation of the giant porpoise is typically 10–11 months. Most births occur in late spring and summer. Calves are weaned after 8–12 months. Their average life-span is 32 years, although individuals have reached 40 years. The conservation status of the giant porpoise is Least Concern due to successful conservation efforts and the giant porpoise's wide range.
