Preying Mantas
From the Super Mario Wiki
A Preying Mantas is a Jellyfish found in the waters in Super Mario World 2: Yoshi's Island. They move up and down in a small area, and therefore do not pose much of a threat to the Yoshis. The Yoshis can only attack them when in submarine mode; they are also only encountered while in this form.
It is possible that the Preying Mantas are related to the salt-water dwelling Jellyfish from Yoshi's Story.
A creature resembling Preying Mantas also appears in Super Mario Galaxy, in the Deep Dark Galaxy and the Bigmouth Galaxy.
[edit] Trivia
- "Preying Mantas" is a pun on praying mantis.
