"The turtle eats an apple."
Translation:La tortuga come una manzana.
so if an animal has two forms would you use the male if gender of the animal is unknown, or do you go the the gender that best suits the animal? ie unknow sex dog perro unknown sex cat gata?
In almost all cases, when an animal has both a masculine and feminine form and the gender of the animal in question is unknown, the default usage would be the masculine form i.e. "el gato" or "el perro". As with all things, there are a few exceptions which can be found in the links below.
