Hand-carved ironwood bowl, abstract fish shape, vintage African art?

Hand carved wooden bowl with cover, fish shape, measures about 7" across the bowl (not including the fins or the tail).

This isn't marked with an artist or country or origin, though we believe it's made of ironwood (red and black grained, moderately heavy, very beautiful wood!). It came to us with a collection of world folk art pieces, mostly pieces from Africa. We wish we knew more about it, but that's about the extent of what we know about this piece. (We wonder why the fish was made without a head?)
