Harbour porpoise skeleton on display. The harbour porpoise is a little smaller than the other porpoises, at about 67â85 cm (26â33 in) long at birth, weighing 6.4â10 kg. Adults of both sexes grow to 1.4 to 1.9 m (4.6 to 6.2 ft). The females are heavier, with a maximum weight of around 76 kg (168 lb) compared with the males' 61 kg (134 lb). The body is robust, and the animal is at its maximum girth just in front of its triangular dorsal fin. The beak is poorly demarcated.
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.
