Eftsalae (plural) lay their eggs in clusters around the base of stalks of cattails. The shells are sticky which keeps them anchored to each other and the reeds.
When Eftsala eggs hatch the newborn Eftsalae are relatively weak and stick together in clusters for safety. During this phase of life the Eftsala do not leave the water. An Eftsala's skin needs to stay damp, if an Eftsala's skin dries out too much they will die. As the Eftsala in a cluster grow and become more self-sufficient the cluster will disintegrate as the individual Eftsala go their separate ways. It is around this time that the Eftsala develop a similar ability that of the Trisk, they are able to manipulate and carry water with them. This allows the Eftsala to leave the water for varying lengths of time, the longest on record being 3 and half hours.
