Estuarine seahorse
Hippocampus kuda
Family Syngnathidae
updated Dec 13

Where seen? This large seahorse is sometimes seen on our Northern shores, among seagrasses. According to the Singapore Red Data Book, the Estuarine seahorse (Hippocampus kuda) is found mainly in seagrass areas near sources of freshwater. The Estuarine seahorse is found all around Singapore in shallow waters.

Features: 6-10cm long. Body without large, obvious spines. Colours seen include yellow, brown, sometimes pinkish or even orangey. Some have spots on the body. Often seen in a pair near one another: One is bright yellow, the other is dark; brown or even black. Sometimes, very tiny ones only about 2cm long are seen among seaweeds.

It's difficult to tell this seahorse apart from the Tiger-tailed seahorse (Hippocampus comes). More on how to tell apart the Tiger-tail and Estuarine seahorses.


Status and threats: Seahorses are listed as CITES II (which means their international trade is monitored) and are considered globally vulnerable. Hippocampus kuda is listed as 'Vulnerable' on the Red List of threatened animals of Singapore.
