I would be surprised if you can successfully catch a full grown adult on your first try with a fishing rod

DATABANK:
The Saberfish can be a devastating creature.

Among the fastest fish, at 60 mph, as well as bring 3m long, it is a skillful predator. Having a total of 6 blade-like armor: 1 on the dorsal fin, 2 on the pectoral fins, then 2 more on the tail fin, and a primary one at the snout. The Saberfish uses it's primary blade to hunt, tearing preys apart by slashing at them, while the other 5 are largely used for self defense.

It won't directly attack people, but will not hesitate to retaliate if provoked. It's meat is edible, but is highly discouraged for obvious reasons.

Study shows that it's scales are highly resistance to each other's blades. Males would battle each other for the female.

Saberfish is solitary, but a small group are observed to follow pirate ships. They are rumored to cut through the ship hull and eat the passengers, or wait for someone to jump off the ship, but so far no evidence were discovered.


Assessment: Stay clear of them, you're not gonna beat them in a sword fight!
