Shark Fin

The Shark Fin is a crafting material that has a 98% chance of being dropped by Sharks found in the Ocean biome, and a chance of being dropped by Sand Sharks during a Sandstorm.

Tips

 * Sharks themselves can be frustratingly rare in the Oceans, so various alternatives can be taken to acquire the fins:
 * Hunting the ocean during a Blood Moon will find a good deal more Sharks, as well as the enemies producing some scarce dyes. A Gills Potion (or in Hardmode, a Neptune's Shell or upgrade) will help, or you can build a breathing area underwater.
 * In Hardmode, it might be easier to obtain Shark Fins from Sand Sharks as they spawn in the surface layer of the desert during a Sandstorm.
 * Shark fins can also be obtained from Shark Statues.
 * As with all mob farms, use the Water Candle and Battle Potion to increase spawn rate.
