Phytoplankton

Main Info
Phytoplankton is the first creature that appears in Birthdays The Beginnings. Phytoplankton will spawn on your map if water is on the map. Phytoplankton thrives in Shallow Waters and cannot actually be captured due to it being invisible, representing how small it is in real life. Phytoplankton is the starting point of the evolutionary tree in the game.

Behaviour
Phytoplankton cannot be seen and thus can't be captured but it automatically saves on the tree. Phytoplankton's behaviour is to grow to large quantities until it evolves down the tree

Evolving
Phytoplankton can evolve into Zooplankton only when the temperature and adaptation rate is right in the shallows.

Trivia

 * Phytoplankton is not visible on the map
 * Phytoplankton is one of few creature that are completely invisible in the game
 * This is only one of the few plankton species in the game
 * It evolves into Zooplankton when the temperature is right and if there is enough space for it to spawn.
