Although the striking white color of a marine mammal can translate into great enthusiasm from the public, having leucism or albinism can be problematic because the animal isn't able to camouflage in defense against predators. Leucism can also cause harm to vision, hearing or skin, says Regina Asmutis-Silvia, executive director for WDC in North America.
But there are outside threats to the white harbor porpoise in the video, including gray seals, who want to eat them. Other threats are ever-present toxins, which can cause problems for the small-toothed porpoise's immune system and liver, and gillnets - which are used in the fishing industry. The porpoises get caught in the nets and drown, explains Asmutis-Silvia.
But this beautiful porpoise has outlived all the threats so far, notes Ritter. "It appears that this is an adult. And although it's susceptible and more visible, it has made it until adulthood without being predated."
Let's hope things stay that way.
