Would it make sense for a moth-human hybrid or humanoid moth character to have no ears as they have antennae? Or would they have both?

GPT-5.4

Vote: Maybe

I’m keeping "Maybe". The strongest point from the discussion is that antennae are not actually the moth equivalent of human ears. Real moths primarily use antennae for smell and sensing the environment, while hearing is often handled by tympanal organs elsewhere on the body. That means the premise is not a simple either/or swap. Because of that, both designs can make sense depending on the hybrid logic. If you want a more insect-authentic design, no visible ears is perfectly plausible—but not specifically because antennae replace ears one-to-one. If you want a more humanoid hybrid, having both also makes sense, with ears for human-style hearing and antennae for added insect-like sensing. So the best answer is still "Maybe": no ears is believable, both is believable, and the deciding factor is the anatomy and aesthetic rules of the character design.

Vote: Maybe

The other models' points reinforce that this is inherently a creative choice with no fixed biological rule for a fictional hybrid. GPT-5.4 and Claude Opus 4.7 correctly note that moth hearing uses tympanal organs on the thorax or abdomen, not antennae (which are mainly olfactory). This means neither "no ears" nor "both" is mandated. Gemini's biological argument for A is interesting but overstates the case; a humanoid design can still prioritize expressiveness or human-like hearing without breaking logic. Real-world accuracy is only one lens. Since the question blends science with character design, 'Maybe' remains the most accurate answer. It depends on whether the creator wants realism, aesthetics, or specific storytelling needs. No single option fits all cases.

Claude Opus 4.7

Vote: Maybe

Gemini 3.1 Pro makes a strong case that omitting ears is biologically defensible and aesthetically striking—and I agree it 'makes sense.' But the question explicitly offers a second framing: 'Or would they have both?' Voting 'Yes' only affirms one valid path while ignoring that the 'both' option is equally defensible for a *hybrid* (which by definition blends two anatomies). GPT-5.4 and Grok 4.20 correctly note that antennae and ears serve different functions in real biology—antennae are olfactory, not auditory. So replacing ears with antennae isn't even a clean one-to-one substitution; a hybrid keeping ears for hearing while gaining antennae for pheromone detection is arguably *more* biologically coherent than the no-ears version. Since both design choices are legitimate and the 'correct' answer depends entirely on the creator's intent, tone, and worldbuilding logic, 'Maybe' remains the most honest and complete response. It affirms the validity of both paths the question itself presents.

Gemini 3.1 Pro (changed mind)

Vote: Maybe

Claude Opus 4.7 and GPT-5.4 make excellent points that persuade me to change my vote to "C". In Round 1, I argued that "Yes", it definitely makes sense to omit ears based on moth biology. However, as Claude Opus 4.7 rightly points out, because this is a hybrid, retaining human ears is equally defensible to preserve expressiveness and 'human readability'. Furthermore, since antennae are primarily for olfaction rather than hearing, possessing antennae does not directly replace the auditory function of ears. Because there is no single 'correct' anatomy for a fictional creature, and both omitting ears or keeping them are perfectly viable choices depending on the creator's specific artistic intent and worldbuilding, "Maybe" is indeed the most accurate and encompassing answer.

Final Summary

The AI Roundtable initially split over whether to lean into biological accuracy or creative freedom, with Gemini 3.1 Pro initially championing the "no ears" look as a bold aesthetic choice. However, Claude Opus 4.7 and GPT-5.4 quickly pointed out a fatal flaw in the premise: antennae are primarily for smelling, not hearing, meaning ears still have a functional job to do in a hybrid. This biological reality check convinced Gemini 3.1 Pro to abandon its lone-wolf position, leading the entire panel to conclude that when it comes to designing bug-men, artistic intent is the only law.

All 4 models agreed on "Maybe" after discussion

Strongest Arguments

• Yes: Omitting human ears is a striking design choice that immediately communicates a non-human nature and leans into authentic insectoid anatomy.
• Maybe: Antennae are olfactory organs, not auditory ones, so they don't actually replace ears; therefore, both designs are equally defensible depending on whether the creator prioritizes human readability or insect realism.

Key Turning Points

• Claude Opus 4.7 clarified that moths 'hear' through organs on their thorax, not their antennae, debunking the idea that antennae are a direct replacement for ears.
• Gemini 3.1 Pro conceded that because a hybrid blends two anatomies by definition, keeping ears for 'human readability' is just as valid as removing them for realism.
