Name and Scope
The inventory retains Rivulus marmoratus, while modern accounts use Kryptolebias. Older regional records can include populations whose classification has since changed. Locality and the original scientific identification should remain attached when comparing broad mangrove-rivulus descriptions.
Water and Moist Shelter
Fish occur in shallow muddy brackish waters and can use crab burrows, moist leaf litter and decaying mangrove wood. Air breathing supports time outside open water, but moist refuge conditions remain important. These observations do not establish unlimited survival in dry surroundings.
Reproduction and Measurements
Self-fertilizing hermaphrodites and males occur in the species account. Their proportions vary, so one fixed sex ratio should not be assigned to all populations. A maximum from an older combined account is not treated as independently verified for every modern taxonomic interpretation.
Keep Moisture in the Habitat Description
A fish inside a log or burrow may be using damp shelter. Do not confuse amphibious behavior with independence from moisture.
