I'm not too sure about the slowest growing animal in general but I do know that the Royal or Wandering Albatross take roughly 6-10 years to reach maturity and are therefore, the slowest growing birds on the planet.
The slowest growing animal on Earth is the tortoise. Unsurprisingly, they also have one of the longest life expectancies of any animal on Earth, living up to 190 years.

The slowest animal on water and on land would have to be a competition between the snail and the turtle .
