Family Syngnathidae

Where
seen? This seahorse is sometimes seen on many of our Northern
shores, among seagrasses. According to the Singapore Red Data Book,
it is found mainly in seagrass
areas near sources of freshwater and found
all around Singapore in shallow waters. 'Kuda' means 'horse' in Malay.
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, not necessarily in the same colour: e.g,. one is bright yellow, the other is dark;
brown or even black. Sometimes, very tiny ones only about 2cm long
are seen among seaweeds. These tend to be 'hairy'.
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. |
Often seen in a pair.

Pregnant fathers: Seahorses reproduce
in a peculiar way. It is male that carries the eggs in his body and
thus becomes 'pregnant'. The female lays her eggs in his pouch.
Emerging from the eggs, the babies hatch as miniature seahorses and
may remain in the pouch for a while before the father goes into 'labour'
and ejects them out of the pouch. |

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. |
