Aquatoid

The Aquatoid is a genetically engineered, ancient alien race closely related to their space/land based cousins, the Sectoid race. Some experts have disputed that the Sectoid race actually descended from the Aquatoids, judging by the webbing on their feet and hands.

Aquatoids possess average weapon skills and are extremely vulnerable to all weapons, including the rudimentary harpoon family. However, higher ranked Aquatoids are feared for their Molecular Control ability.
