Olive’s Wet Beast Fact: these zombie-looking deep sea fish are one of the most abundant species on Earth, with estimates that there are up to a quadrillion individuals. This would make them the most abundant vertebrate on the planet.
These fish are capable of self-amputation. Adult and older juvenile Russell’s oarfish frequently have a part of their tail missing, ranging from just the very tip to up to the fish’s abdomen. The lost parts never grow back, and the oarfish may be able to perform self-amputation several times in their life.
