Safety codes for visits to the soft shores

  • Avoid touching the sap of the mangrove trees - especially that from ​Excoecaria agallocha, which is poisonous and can cause skin irritation.

  • Do not eat the fruit or any part of the flora. Some species, such as the mangrove associate Cerbera manghas, are poisonous.
