Jayakar's seahorse (Hippocampus jayakari) is a species of coastal fish of the family Syngnathidae. It is found in the Western Indian Ocean, from the Red and Arabian seas to the central coast of Pakistan.[1] It lives in seagrass beds (such as Halophila spp.), algae, soft-bottom substrates, sponges, and rocky habitats, where it can grow to lengths of 14 centimetres (5.5 in).[2] It can inhabit depths to 20 metres (66 ft), though it is more commonly found at 2–3 metres (6.6–9.8 ft).[2] It is expected to feed on small crustaceans, similar to other seahorses. This species is ovoviviparous, with males carrying eggs in a brood pouch before giving birth to live young.[1] Individuals reach sexual maturity at 11 centimetres (4.3 in).[2] The specific name and the common name honours the Indian physician, linguist and ichthyologist Dr. Surgeon-Major Atmaram Sadashiv "Muscati" Jayakar (1844-1911).[3]
