Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 10 - 15; Espinas anales: 0; Radios blandos anales: 11 - 13; Vértebra: 34 - 37. Branchiostegal rays: 5-6 (Ref. 36572).
Body shape (shape guide): elongated.
Commonly found in bays and salt marshes near shore, may enter freshwater (Ref. 36572). Often used in laboratories for environmental studies. Not a seasonal killifish. Is very difficult to maintain in aquarium (Ref. 27139). Oviparous, with micro-nektonic larvae (Ref. 36572). Single demersal eggs are attached to spawning substrate via small weakly adhesive filaments (Ref. 36572).
