A billfish drawn as a piece of decorative line art. The long bill, the raised sail-like fin and the deeply forked tail are filled with swirls, scallops and fine parallel strokes, so the page rewards slow, unhurried work rather than quick blocks of color. Many adults find that filling one small shape at a time is an absorbing way to spend an hour. Free to download and print as a PDF, with no registration.

Have you ever seen a really big fish — out at sea, at a market, or in a photograph?
Did anyone in your family fish? What did they bring home?
Which part would you like to color first — the bill, the sail fin, or the tail?
If you could watch one sea creature swim past you, which would you choose?
What kind of fish is this?
It is a billfish — the group that includes marlin, sailfish and swordfish, and which Japanese covers with the single word kajiki. The artist has emphasised the long slender bill and a tall dorsal fin carried like a sail, so you can color it as a blue marlin, a black marlin or a sailfish, whichever you prefer.
What is the long bill for?
Mainly for feeding. A billfish swipes the bill sideways through a tight ball of small fish to stun them, then turns back to collect what it has struck; the old picture of a fish spearing its prey head-on is largely a myth. The bill also helps it slip through the water. Billfish are among the fastest swimmers in the ocean, though the very high speeds often quoted are hard to measure and describe short bursts rather than cruising.
Any tips for coloring this much fine detail?
Work in small sections rather than trying to finish a whole fin at once, and keep the pencil sharp — many of the swirls are narrow. A lot of people choose three or four shades of blue and silver and repeat them across the body so the pattern holds together, then leave a few shapes white to suggest the shine on the scales. There is no correct order; the pleasure is in the pace.
