Straits of Johor

Description

The Straits of Johor (or Johor Strait) runs along the north of mainland Singapore, separating Peninsular Malaysia and Singapore. The Straits is divided by the Woodlands Causeway which links Singapore to Johor Bahru in Malaysia. The Causeway effectively cuts off the flow of currents through the Strait of Johor, turning both sides of the Causeway into cul-de-sacs. The Straits is narrow and relatively sheltered with restricted water circulation. It is not as busy as the Straits of Singapore, which is located in the south of mainland Singapore.

Coastal and nearshore marine habitats along Singapore’s northern coastline have been affected by the construction of the Causeway in 1923. Bordering the Straits of Johor are mostly mangroves. Some of Singapore’s most diverse mangroves are found here. Reefs can also be found at Pulau Ubin and Pulau Tekong which lie in the east of the Straits of Johor. 133 species of fish belonging to 46 families have been recorded from the east of the Straits. A large pod of 20 to 30 individuals of the Bottlenose Dolphin (Tursiops truncates) were also spotted in these waters in 1998. The dolphins stayed for a few days close to the former Punggol Marina .
