"I am a turtle."
Translation:Ik ben een schildpad.
This is the result of PC culture! We are now unsure of our own species! Down with PC culture! :') /s
No, except if you're saying something like your name, nationality or describing a characteristic. For example, I would say 'Ik ben otterbaskets' ( I am otterbaskets ) or 'Ik ben Nederlands' ( I am Dutch ) or 'Ik ben rood' (I am red). It's pretty much the same as in English. If you use a / an in the original sentence, then you use 'een' in the translation.
