Piscobalaena (SciiFii)

The dwarf fin whale (Piscobalaena nanoceta), also known as the pygmy fin whale, is a species of cetothere whale which originally lived from the Middle to Late Miocene epochs (about 11.6 to 5.3 million years ago) in Peru and Florida as an extinct species, Pisconalaena nana, and was once extinct, but has since been brought back from extinction by SciiFii and introduced throughout the modern Pacific and Atlantic Ocean to help boost biodiversity. The dwarf fin whale resembles other, larger baleen whales such as blue whales, but is much smaller, growing only to be about 16 feet (5 meters) in length and weighing around 10 tons at a time. Like humpback whales, it is known for breaching and other distinctive surface behaviors, making it popular with whale watchers. Males produce a complex song lasting 10 to 20 minutes, which they repeat for hours at a time. All the males in a group will produce the same song, which is different each season. Its purpose is not clear, though it may help induce estrus in females. They feed in polar waters, and migrate to tropical or subtropical waters to breed and give birth, fasting and living off their fat reserves. Their diet consists mostly of krill and small fish. Dwarf fin whales have a diverse repertoire of feeding methods, including the bubble net technique. The conservation status of the dwarf fin whale is Least Concern due to successful conservation efforts, the dwarf fin whale's wide range and its tolerance to many of the human activities.
