Urocaridella antonbruunii can reach a body length of about 25–30 mm (0.98–1.18 in). Like the other species of the genus Urocaridella, have very long rostrums curved upwards, transparent bodies, and numerous brightly-coloured red and yellow spots on the carapace and abdomen.

Why this record matters
The phrase “species of crustacean” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Feb 6, 2026. The linked authority identifier is Q3933825. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1967.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
