Hi again novice, I don't have the puzzle I front of me so I'm doing this from memory.
In row order,
F = 4 cells
Creatures split over 3 descending rows, 1,3 & 5 cells with the specific holder having its "head" in the cell 2 left of the 5 above then the next symmetrical 7 followed by 2 high which contiguously spell its name.
