Tektite

The Tektite is a one-eyed spider enemy that has appeared in almost every Zelda game. It comes in several varieties, including Red Tektites, Blue Tektites, and Golden Tektites. They are usually found in mountainous areas, such as Death Mountain and Mount Crenel. Blue Tektites also posses the ability to walk on water. Tektites attack by jumping at Link. The Tektite is considered a "normal enemy", considering it only takes one or two sword swipes to defeat (depending on which sword/upgrades you have). Projectile weapons, such as slingshot seeds or arrows work as well. The hookshot or longshot is somewhat effective. It does not defeat the Tektite, but it does paralyze it for a brief moment, which is helpful, because of the Tektite's movements it can be quite annoying.

Being that Tektites have appeared in almost every Zelda game, it is important to note that their attack pattern has hardly changed at all since they were first introduced. Physically, Tekities have seen drastic differences over very many games, but attack wise, they remain the same.

Quote from The Legend of Zelda: The Minish Cap Tektite figurine: "Appears on Mount Crenel, etc. They move by jumping long distances. Their movement can be unpredictable so attack them when they are still."

They also appear in Phantom Hourglass as enemies in many places, such as the Isle of Ember.
