The seahorse is a distinctive sea creature that has both gentle & graceful characteristics, those that mirror that of the multiple ethnic and cultural identities of Miri who live in peace and harmony. A seahorse figures also sits very well with projecting an image of a serene seaside coastal city with beautiful coral reefs as a diving haven and resort paradise, which it is. The mascots have names; MiMi and RiRi, and this is why in Miri the seahorse sculptures are almost always in pairs.
The Seahorse as a mascot was proposed by the former Sarawak chief minister and introduced during "I love Miri campaign" in 1994.
In the late 1990s, around 1998 or so, a minister had flown over a newly-formed island at the Baram delta and saw that its shape is reminiscent of that of a seahorse, and named it "Seahorse island", or "Pulau Kuda Laut / Pulau Unduk-unduk". That island has since changed shapes, and its name has changed just as many times.
There are many seahorse sculptures around Miri by 2015. Pictured is the one at the Miri-Airport road roundabout, taken in 2006.
