Questions

Where is the semicircular canal?

It sits in the head, within the sensory system. Positioned deliberately as part of this species body plan.

What does the semicircular canal connect to?

Part of: internal ear and membranous labyrinth.

Is the semicircular canal the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
