Version: 1.0
Reviewed: 2026-08-12
Topic: Sex shrimp with stated confidence

Situation: You want to classify a shrimp as male, female or uncertain.
Observe first: Use clear lateral and dorsal observations and note size, maturity, abdominal form, ovarian tissue and attached eggs separately.
First action: Assign only the confidence the visible evidence supports and keep uncertain or immature animals unclassified.
Record next: Record image date, view, landmarks used, confidence, later ovarian development, attached eggs, mating or hatch confirmation.
Stop boundary: Do not use colour, size or a vague saddle alone as universal proof of sex, maturity, fertility or reproductive outcome.
