Men's subsistence technology, at least for Savanna Pumé, uses bows and arrows for terrestrial hunting and much fishing, modern fishing line and hooks (if available through trade), specialized harpoons or arrows for caimans or turtles, as well as knives and machetes. Bows are made from palm wood ("Astrocaryum" "jauri".) and are long (~2 m) as are most South American native bows. Bowstrings are made from a semi-cultivated bromiliad fiber ("Ananas lucidus"). Arrows, (also ~2m long) are made from domesticated arrowcanes, wooden foreshafts, fletched with anhinga feathers, and constructed with bromiliad fiber and a manufactured tree resin ("Symphonia glubulifera"). Scavenged, traded, and re-used pieces of metal are used for arrowpoints, probably at least since the mid 19th century. Bone is reported to have been used before metal was as common, and two wooden-tipped bird arrows are still occasionally employed. Some River Pumé men have access to guns for hunting. Because most hunted foods in the savannas are burrowing game (armadillos, tegu lizards, and small ameiva lizards), machetes and especially bows often are used as digging implements to capture these game. During the dry season, small rafts made from moriche plalm leaf stems are used to search for caimans and turtles in seasonal lagoons. River Pumé use dugout canoes for fishing, pursuit of caimans, and turtles in the major drainages of the llanos, as well as for transportation.
