Mantras are bottom feeders that are relatively harmless. They are however eaten so they have occasionally brushed with extinction. They have always persevered though.
I am enchanted with marine-biology and one of my favorite creatures are rays. So I made a LEGO one. I originally got inspired by the 1.0 torsos looking like ray-wings. Ironically I later switched the 1.0 torsos for 2.0 torsos, I think this is the only instance where I have been inspired by a certain piece only to not use it. I particularly like the group shot where it was getting all "under da sea". I also made a little kelp organism to display with it. I envision that kelp producing crystals/coral as a by-product of it's metabolism. The crystal design was originally from LegoJang in case anyone was wondering
