Etymology: Cyprinodon: Latin, cyprinus = carp + Greek, odous = teeth (Ref. 45335).
Issue on validity of subspecies: subspecies elevated to species rank in FB, synonymized with the species Cyprinodon variegatus Lacepède, 1803 in Eschmeyer (CofF ver. Mar. 2011: Ref. 86697). Please send references, or more studies are needed.
Environment / Climate / Range
Freshwater; benthopelagic; non-migratory. Subtropical, preferred ?
North America: Lake Eustis and other headwater lakes of Oklawaha River in central Florida, USA. Possibly not different from Cyprinodon variegatus.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 5.0 cm TL male/unsexed; (Ref. 27139)
Occurs in lakes. Not a seasonal killifish. Is difficult to maintain in aquarium (Ref. 27139).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00452 - 0.02213), b=3.24 (3.06 - 3.42), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 2.9 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (11 of 100) .
