On the subject of Lekku, how appropriate is it to use as a term for head appendages in other species, like Nautolans and Ozrelanso?
Here's a page featuring the most prominent species with similar organs. These are the terms most appropriate but most people will know what you are referring to if you describe them as 'lekku'.
'Lekku' is the most versatile term and it is not considered derogaory to any species, whereas 'head-tail' is disliked by twi'leks and 'tendril' or 'tentacle' are more specific to those seen on feeorins and nautolans.
I hope this helps!
