A Fish With Human Teeth
Here’s something for Paleo folks to ponder.
The pacu fish feeds on tree nuts, so its teeth are very human.
Acorns were a substantial part of the ancient Greek diet.
According to “Pacu,” Wikipedia (updated Sept. 12, 2019) …
“Pacu and piranha do not have similar teeth, the main difference being jaw alignment; piranha have pointed, razor-sharp teeth in a pronounced underbite, whereas pacu have squarer, straighter teeth, which are uncannily similar to human teeth, and a less severe underbite, or a slight overbite. Pacu, unlike piranha, mainly feed on plant material and not flesh or scales.”
Is the pacu a testicle-biting fish?
No. Despite the media buzz, it’s safe for men to skinny-dip in the vicinity of a pacu.
They only eat tree nuts and fruit.
Michael Goulding (The Fishes and the Forest: Explorations in Amazonian Natural History, 1980) wrote …
“Pacu characins of the genera Mylossoma and Myleus are major seed predators of the Rio Machado flooded forests. They eat mostly seeds about 0.5-1.0 cm in greatest diameter (including nut wall) when round or semispherical; some flattened, disk-shaped seeds were considerably larger but their maximum depth was no more than about 0.5-1.0 cm, which enables the pacus to easily bite out chunks of them.”
According to the same source …
“Overall, however, the pacus probably play only a very minimal role in seed dispersal in the Rio Machado flooded forests. They are seed predators par excellence.”
As were the ancient Greeks.
