There is very little information known about Halodule ciliata. It is only known from Taboga Island, Panama where it has not been recorded since 1970. Research on all aspects of its ecology are recommended. Investigation into possible threats to this species are also recommended as it has a very restricted distribution and could possibly be placed in a threatened category if more information was known, or may possibly be extinct. This species is listed as Data Deficient.

Population [top]

Population:There is very little information about this species, which is known only from herbarium specimens. In 1970, the Panama population was considered to be a possible relict (den Hartog 1970). Field surveys looking for the population in 2009 found no seagrasses around Taboga Island in Panama (A. Prathep pers. comm. 2009). Additional thorough surveys and searches along the Pacific coast of Panama are needed to determine the current status of Halodule ciliata, as this species may be extinct.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No
