Generally, H. kuda inhabit shallow inshore areas with an average depth of 0 to 8 m, but they have also been found at a maximum depth of 55 m (Lourie et al., 2004). They can be found in mangroves, coastal seagrass beds, estuaries, coastal bays and lagoons, harbors, sandy sediments in rocky littoral zones, and rivers with brackish waters (Lourie et al., 2004; Job et al., 2002). Spotted seahorses have also been found attached to drifting Sargasssum as far as 20 km from shore (Foster et al., 2003).
