QD's Mutant of the Week!
It has taken months of dedicated work on the part of the staff at British Mutagen (BM) to create this useful mutant. Luckily there is still plenty for this animal to do! This cetacean can collect huge amounts of oil in its modified horn, and then separate oil from water inside its body. Pure crude oil is then ejected from its blowhole. Tar-whals can also live off of crude oil indefinitely, so they do not threaten marine habitats.
