Preying Mantas

A Preying Mantas is a jellyfish found underwater in Super Mario World 2: Yoshi's Island and its remake Yoshi's Island: Super Mario Advance 3. Its name is a pun on, a kind of insect, and , a kind of stingray. Preying Mantas move up and down in a small area, and therefore do not pose much of a threat to the Yoshis. The Yoshis can simply defeat them by shooting a torpedo at them in their Submarine forms. They appear again as enemies in Yoshi's New Island.

Yoshi's New Island

 * Shogakukan guide: 潜水艦に変身して水中を進むときに出現する. 攻擊してくることはないが、上下にゆっくりと移動する. 触れるとタイムロスとなるので、避けるか魚雷で倒そう. (They appear when you transform into a submarine and proceed underwater. It does not attack, but moves slowly up and down. Touching it will cause time loss, so avoid it or use torpedoes to defeat it.)
