Bit confused here. Can it not be "Jullie zwemmen naar de schildpadden toe?" since it is "towards the turtles" and not to the turtles?
It can, and it is accepted.
Thanks a bunch!
How can you know if the translation is "you swim towards the turtles" like in this case or "you are swimming towards the turtles" which isn't accepted?
Not a native Dutch speaker but I believe this is how it works...
You swim towards the turtles. = Jullie zwemmen naar de schildpadden.
You are swimming towards the turtles. = Jullie zijn aan het zwemmen naar de schildpadden.
Could anyone enlighten me on when to use the various "to" prepositions?
That'll probably a long (and boring) list. Prepositions are used differently in different languages, even in ones as common as Dutch and English.
You can start by reading this explanation on prepositions: https://www.duolingo.com/comment/3782321
Are you serious?! I wrote 'schilpaden' with one D and they marked the whole sentence as wrong but other times they accept typos. Wtf duolingo??? Make up your mind
Report it as a typo.
Shouldn't this sentance have an exclamation point? They might be snapping turtles, in which case if spoken it would be said with alarm, as a warning.
Can you use aan here?
Is this like へ?
