"Los elefantes beben agua."
Translation:The elephants drink water.

You are correct that some animals have both masculine and feminine word counterparts, like with 'un/los gato(s)' or 'una/las gata(s)'. That said though, not all animal genders follow this pattern.
In your second example, 'el caballo' can refer to simply a horse that you don't know the gender of, or a male horse/stallion. 'La caballa', on the other hand is not a horse at all, but a type of fish (mackerel)! 'La yuega' would be the word you are looking for if you wanted to say a female horse/mare.
(Nitpicking now, but a filly is actually a young female horse, and would be 'la potranca') :) Included below is an excerpt from more in-depth explanation of the topic, with the link included at the end!
- Some animals have both a masc. & fem. form that look very similar (e.g. '
o/a' or '
- And some use the same word regardless of animal's gender, even though they may look similar to other gendered nouns. (e.g. '
a(f.)' or '
- Some may have different words for both genders (e.g. '
una vaca(f.)' or '
- And sometimes the word that looks like the word for the opposite gender means something totally different (e.g. '
un pato(m.; 'a duck')' & '
una pata(f.; 'a leg')')
When there is a vowel as the last letter of the noun, to get the plural, just add an "s" and keep the vowel the same. With a constanant as the last letter, add "es". Because elephante ends with the vowel "e", all you would do to get the plural is add an "s", making it elephantes.
