The Triplewart Seadevil

Triplewart Seadevil has an extreme difference between the sexes. Females grow much larger, while males can attach to females and become dependent on them.

Range and Identity

Cryptopsaras couesii is recorded circumglobally in tropical and subtropical ocean regions. That broad distribution does not mean the sexes or life stages are encountered equally. A small male and a large female can look so different that their measurements require explicit sex labels.

Habitat and Behavior

The account describes dwarf males becoming parasitic on females. Free-living males are much smaller than the largest female reference. These are sex and developmental distinctions, not conflicting measurements of a typical adult body size.

Food and Life History

The upper female reference is forty-four centimeters total length, exceeding the 7.3-centimeter male or unsexed header value. Females lay eggs and larvae are planktonic. Floating gelatinous egg rafts are proposed in the summary, but are not treated as a directly confirmed species-specific observation.

Field Note

Always retain sex with a size record. Reporting only a small male measurement as the species maximum would substantially understate the documented size of females.
