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.

    Re: So, shouldn’t we be eating wild Alaskan salmon?

    The orange roughy is the lowest in DHA, and can live 150 years.

    Ray Peat said 200 years.

    A wild salmon is extremely lucky if it can reach 8 or 9 years.

    Orange roughy oil is a treatment for dry, scaly skin.
