There are more nerve endings in Cufant’s trunk than the rest of its body combined. Cufant studies objects by gripping them with its trunk and rotating them endlessly, letting go when its curiosity is satisfied. With its grip strength, practically nothing can interrupt this process.

Copperajah are too heavy to swim, but their migration routes cross many rivers. To overcome this, Copperajah walk on the bottom and hold their trunk above the water’s surface. Copperajah can walk underwater all day this way, resurfacing miles away from where they started.
