- •. The already rare Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis) faces an 80 percent drop in its population over the next 30 years, according to research by the Institute of Hydrobiology of the Chinese Academy of Sciences.

Building a Hippo Home Everything is super-sized, says Boecker. This is especially true when working with hippos since they are the second largest land animal on the planet (elephants are the largest). On average, female hippos weigh up to 3,000 pounds and male hippos can weigh up to 6,000 pounds. So you can imagine that animals this large are going to require heavy-duty enclosures with sturdy floors, extra-strong walls, and steel-reinforced gates.
