Its PoisonTail is, well, poisonous. This enemy only has 1 HP, but it carries the Megalixir, which heals your entire party. Try to steal it!
The Land Ray is an enemy in Final Fantasy VI.
It enters battle with Sap status and one HP, so it will die as soon as it takes its first turn. However, rare Megalixirs can be stolen from it, and it is one of the few enemies that can teach Strago the rare Mighty Guard Lore. It is recommended to cast Stop on the Land Ray, preventing Sap from killing it, then have Locke and Gogo Steal from it while Relm Sketches it to cast Mighty Guard for Strago to learn. Alternately, equipping Locke or Gogo with a Thief's Glove and Master's Scroll and using Mug allows four stealing attempts. Oddly, despite having one HP, it has Protect.
