Fundulus nottii
species of fish
Fundulus nottii, the bayou topminnow or southern starhead topminnow, is a fish of the family Fundulidae found in the southeastern United States.
Description
It is a small topminnow with a sub-ocular teardrop, a terminal to superior mouth, and a rounded caudal fin. The top of the head is flat, with the large scale (located just anterior to a line between the eyes) overlapped by the pair of scales just behind it. The lateral line is absent, and there are 11 preoperculomandibular pores. The sensory pores are fused. There are 7-8 dorsal rays, 9-10 anal rays, 11-12 pectoral rays, and 6 pelvic rays. During the breeding season males develop prickly contact organs on the anal fin. The Largest reported specimen was 65mm (2.6 in) long. They are sexually dimorphic. Both sexes have a back that is olive green with a thin dorsal stripe, sides that are white or silver with an iridescent blue or silvery overlay, and a dark, iridescent blue-green suborbital teardrop.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Fundulus nottii”, the useful work is to connect “species of fish” to the records capable of establishing context and consequence.
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 Jun 7, 2026. The linked authority identifier is Q5853327. None of the 0 selected statements returned an explicit reference.
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.
