Hippocampus tyro, a new seahorse (Gasterosteiformes: Syngnathidae) from the Seychelles
Hippocampus tyro is described as a new species of seahorse from one specimen, 34 mm high and 61 mm in total length, dredged from 43–48 m off Poivre Atoll, Seychelles in 1992. It is unique for the genus in having 14 trunk rings and a single middorsal gill opening. It is compared with two other diminutive species, H. pusillus Fricke and H. jugumus Kuiter, sharing with them a slender body, confluent middorsal shoulder ridges, and similar spination.
