Order: Characiformes
Family: Serrasalmidae
Length: 35 cm
Mass: 1.3 kg
Diet: Other fish
Killing apparatus: Slicing jaws
While usually a relatively placid scavenger, it will swarm injured prey in large shoals. One of the most common piranha species.

Order: Thyreophora
Family: Ankylosauridae
Length: 34 centimeters, but this is a juvenile. Adults would be larger.
Mass: ~1 kg based on relatives, but this is a juvenile. Adults would be larger.
Diet: Fish
Age and Location: Early Cretaceous, 125 million years ago, China
Killing apparatus: Gripping jaws, manual claws
The only known piscivorous ankylosaur. Theorized to live like a modern turtle.

Liaoningosaurus would definitely win this fight with its armor and tail easily trouncing the piranha.

[dinosauria101]

I lean towards it as well - the armor is good protection.
Though the piranha probably stands a better chance than the cookiecutter shark, as their bites are better at bone damage.

Pirahnas have good bite force, but they aren't really fast swimmers and they are inflexible. I've heard of cichlids killing them. I'd go for the fish-killer.

I'd actually use something like hydrocynus vittatus or a wolffish

[dinosauria101]

Depends upon this ankylosaurs' growth rate - it is a juvenile, but we have no way of knowing how much more it would grow - could be anywhere from less than 1 kg more to several hundred kg more.

Although, at parity, a tiger/wolffish or a predatory cichlid would be a good fight.

giant otter?

[dinosauria101]

Probably would favor the ankylosaur there at parity; good armor protection and a nasty bite

[Deleted]

otters are really agile tho and have a good bite force, they kill full grown snapping turtles

[Deleted]

and stamina really isn't on the ankylosaur's side

[dinosauria101]

Dinosaurs in general are thought to have had very good stamina due to advanced respiration, and Liaoningosaurus would be more armored than a turtle - thicker, less rigid, and not in such a way that one bite would shatter it like turtle shells. The superior durability and similar weapons lean me to the dino.

Piranha are actually quite fast. Speciemns often get killed in captivity because unlike in the wild they have nowhere to run. THey're just rather inoffensive.

really? pirahnas don't seem very streamlined to me compared to a salmon or something

Yeah, they are zippy! Streamlined=/=fast, Just look at the Greenland shark.
