Moheeks are fish-like creatures in Metroid II: Return of Samus. They can be seen living in the dangerous liquid but can become land dwellers as well. The top portion of a Moheek's head greatly resembles an anemone.
They are a non-aggressive species, but on contact with their tendrils they cause an extraordinary amount of damage. It has the same AI (artificial intelligence) as a Zoomer. They are found in parts of the main tunnel in SR388.
"Usually quite tame, but if Samus touches its tendrills [sic], she will be hurt badly."
