Fish-like robots (ichthyomorphic):

ichthyomorphic is rarely employed in robotics discussions, where it might appear in broader biological or mythological contexts.

Common alternatives include "robotic fish," "fish-inspired robots," "aquatic biomimetic robots," or "jellyfish-like platforms," with examples like pollution-monitoring robotic trout, jellyfish propulsors, or swarming underwater bots.

Fishoid or Ichthyoid are options, resembling or having the form of a fish, highlighting aquatic propulsion and body shape (from English "fish" + "-oid" or Greek "ichthys" for fish + "-oid").

"Ichthyoid" is a well-established term for fish-like (used in biology and dictionaries), while "fishoid" is informal and easier to understand.

"Fishoid" is rare. Dominant terms are "robot fish," "robotic fish," or "robofish," emphasizing practical, descriptive naming for aquatic biomimics — "fishbot" fits this pattern but isn't common.
