Halimeda Ghost Pipefish

Solenostomus halimeda

Sighting evidence at Eel Garden, Madang

Halimeda ghost pipefish are near-perfect mimics of the segmented green algae Halimeda that carpets the Eel Garden slope, their angular bodies and coloration rendering them invisible to casual observation. Unlike their seahorse relatives, female ghost pipefish carry the eggs in their modified pelvic fins rather than in a male pouch — a reproductive reversal that makes Madang's populations particularly valuable for behavioral research into alternative parental investment strategies.

How is this calculated?

Sighting evidence is compiled from iNaturalist observation records within a set proximity radius, filtered for quality-grade observations. “Last confirmed” is the date of the most recent research-grade record. Record count covers a rolling 24-month window. Confidence reflects record count, recency, and consistency of seasonal signal.
