Turtles live to be between 40 and 100 years old and they move very slowly. You have a quiet day, you are moving or somebody dresses up in carnival as a Teenage Mutant Ninja Turtle.
The turtle emoji was introduced in 2010 and released as part of the Unicode 11.0 standard. This emoji can be found under the animals and nature
category. Because the turtle emoji has been around for quite some time, it should display correctly in the majority of operating systems.
