Pneumatophores can only be found in mangrove trees, such as Ceriops sp, Heritiera domes. These are the aerial roots of certain plants for respiration. In fact, the amount of salt in the soil is excessive in that region. So the root can’t get enough oxygen from the soil. So, some roots are rising upwards and come above the ground. Such roots have many tiny pores on their surface, through which they can absorb oxygen and release carbon dioxide. The pores are known as lenticel.
