  • Aerial Roots (Pneumatophores): These roots help in respiration by obtaining oxygen from the air in waterlogged soils.
  • Prop Roots: Provide stability against tidal waves and storm surges.
  • Vivipary (Seed Germination): Seeds germinate while still attached to the parent tree to overcome the challenge of germination in saline water.
  • Efficient Carbon Sequestration: Mangroves are among the most carbon-rich ecosystems, playing a vital role in mitigating climate change.
  • Ecological Significance: Mangrove forests act as a crucial buffer between land and sea, providing habitat for various marine and terrestrial species.
