They have no idea.
The Arkuaticans would see little fish being taken up into the sky on the wings of skyfish and think "They must be very special fish." Their understanding of the world outside of their underwater reef is very small and limited, so they do create a lot of silly notions around outside sources. Fortunately I think Loka will prove too heavy for the seagull.
Taken from the RIO3 comic of extra-curricular activities, set apart from the main stories of Arkuatica.
