“…Previously, H. mohnikei was only observed in seagrass beds in Japan and an estuary in Vietnam (Lourie et al, ). These habitats, Zostera seagrass beds in estuary and inlet waters, are now some of the most commonly reported habitat associations in Japan (Kwak et al ., ; Otsuka et al ., ), Korea (Choi et al ., ) and China (Zhang et al ., ). In India, two additional genera of seagrass, Halophila and Thalassia , have been associated with the occurrence of H. mohnikei (Thangaraj & Lipton, ).…”

“…In India, two additional genera of seagrass, Halophila and Thalassia , have been associated with the occurrence of H. mohnikei (Thangaraj & Lipton, ). All H. mohnikei have been reported from depths of <10 m (Thangaraj & Lipton, ; Kwak et al ., ; Otsuka et al ., ; Choi et al ., ; Zhang et al ., ). Juvenile H. mohnikei have been found in the offshore waters of Japan, and their occurrence correlated with high density of small prey items (Kanou & Kohno, ).…”

New records of the Japanese seahorse Hippocampus mohnikei from Cambodia, Malaysia, Thailand and Vietnam, along with recently published studies from India and Singapore, have greatly expanded the known range of H. mohnikei within Southeast Asia. These new records reveal novel habitat preferences and threats to H. mohnikei in the region. Although the global conservation status of H. mohnikei is classified as Data Deficient according to the IUCN Red List of Threatened Species, new sightings indicate that this species is found in similar habitats and faces similar threats as other Hippocampus species that are considered Vulnerable.

“…In southeastern Asian coastal waters, H. mohnikei has been reported from Singapore [41] as well as from Cambodia, Malaysia, Thailand and Vietnam [37]. In northeast Asia, H. mohnikei is reported from China [44,56] and South Korea [62,63]. The present report on the occurrence of H. mohnikei in a bay-estuarine system of Goa, CWCI as confirmed by both morphological and molecular analysis represents a significant westward expansion compared to the previously known geographic range of this species [37].…”

“…Association of H. mohnikei populations with seagrass beds (Zostera spp.) in Korea [62,63], Japan [66] and China [44] has been reported. Whereas the specimen reported from Palk Bay, southeastern India [11] was associated with two other additional genera of seagrass species (Halophila and Thalassia).…”

“…Food availability has been considered as one of the factors influencing the abundance and distribution of seahorses [20]. Zooplankton such as Oithona davisae, Calanoida and Penilia avirostris have been identified as the main prey organisms for juvenile and young H. mohnikei in Tokyo Bay [39], whereas the adults have been reported to prey upon mainly larger organisms such as gammarid and caprellid amphipods [63]. Nutrient-rich waters of the Mandovi estuarine system sustain high primary productivity and abundance of zooplanktonic prey organisms such as copepods [69][70][71] which are essential for the survival and establishment of seahorse populations.…”

Morphological and molecular evidence for first records and range extension of the Japanese seahorse, Hippocampus mohnikei (Bleeker 1853) in a bay-estuarine system of Goa, central west coast of India

Accurate information of taxonomy and geographic range of seahorse species (genus Hippocampus) is the first step in preparing threat assessments and designing effective conservation measures. Here, we report first records and a range extension of the Japanese seahorse, Hippocampus mohnikei (Bleeker, 1853) from the Mandovi estuarine ecosystem of Goa, central west coast of India (CWCI) based on morphological and molecular analyses. The morphometric and meristic traits, particularly short snout (29-35% head length), double cheek spine, low coronet, long tail (51.2-57.9% of standard length), 11 trunk rings, 37-39 tail rings, 15-16 dorsal and 12-14 fin rays observed in four collected specimens matched with the reported key diagnostic morphological criteria of vouchered specimens of H. mohnikei. The seahorse mitochondrial cytochrome oxidase subunit I (COI) and cytochrome b (Cyt b) genes were partially sequenced for conclusive genetic identification of the species under study. Molecular analysis showed that all four individuals clustered together suggesting a monophyletic lineage. Using the maximum similarity with GenBank database, maximum likelihood network and subsequent morphological analysis, the identity of the collected seahorse species was reconfirmed as H. mohnikei. With this new report, the geographic range of H. mohnikei extended significantly to the west from its previously known range. This new sighting of H. mohnikei could indicate a long-distance dispersal facilitated by the prevailing oceanic circulation in the Indo-Pacific region or increased habitat suitability in bay-estuarine systems of Goa, CWCI. Comparison of the pair-wise genetic distances (Kimura 2-parameter) based on COI and Cyt b sequences revealed that the specimens examined in this study are genetically closer to H. mohnikei populations from Vietnam and Thailand than they are to those in Japan and China. To test the hypothesis whether H. mohnikei are vagrants or previously unreported established population, long-term inter-annual sampling and analyses are warranted.
