The Stingray is an enemy in Final Fantasy V, a rare encounter that can be found in the sea southeast of the Phoenix Tower and the small lake near Carwen. The area for this encounter is extremely specific: the player must skirt the coast above the sunken Walse Tower. In the GBA version, it can also appear in the River of Souls, in the Sealed Temple.
A particularly easy way to find this enemy in the lake area in the North American and Japanese GBA versions is to Quicksave on the land next to their encounter area, continue, get in the boat, move around a bit, and the second enemy met should be the Stingray.
Befitting its rarity, Stingrays carry a number of useful items and abilities to take advantage of. It is the sole means by which the elusive Blue Magic spell Mighty Guard may be acquired, though the Beastmaster skill Control must be used. The Dragon's Whisker whip is Stingray's highly-valued rare drop - one of the few weapons effective against dragon-type enemies, it makes combatting Shinryu and (in the GBA version) Neo Shinryu easier. Dark Matter may also be stolen as the Stingray's common item, and Rune Blade as its rare one.
The best method to quickly take down a Stingray is to bring a party entirely outfitted with Blue Magic and Level 3 Flare. It is also a good strategy to have a party member that knows the Mystic Knight's Spellblade ability, and the Ranger's Rapid Fire ability. The player should enchant their blade with Flare, and then use Rapid Fire repeatedly. This tactic works well with most enchantable blades.
