![]() This study aimed to answer: (I) Can an artificial water body provide suitable habitat for an endangered seahorse species? And if so (II) what characteristics of this new habitat are important in terms of seahorse utilization? Four major habitat types were identified within the marina canals: (I) artificial reno mattress (wire baskets filled with rocks) (II) Codium tenue beds (III) mixed vegetation on sediment and (IV) barren canal floor. ![]() ![]() Thesen Islands marina, an artificial water body, added 25 ha of new estuarine habitat to the Knysna Estuary in South Africa, home to the Knysna seahorse. as a new species, which is described herein.Īn artificial water body provides habitat for an endangered estuarine seahorse speciesĪnthropogenic development, especially the transformation of natural habitats to artificial, is a growing concern within estuaries and coastal areas worldwide. This combined analysis supports the distinctness of H. In addition, molecular analysis showed all individuals of the new species clustering together suggesting a monophyletic lineage. This species is diagnosed from all other seahorse species by morphological characters, including the lower number of tail rings (35) 15 pectoral-fin rays 16 dorsal-fin rays a rounded nuchal plate without a raised coronet a snout length 30% head length two cheek spines and a dark brown coloration. was collected over shallow seagrass beds in Beibu Bay, China.
