Which animal has the heaviest set of horns growing from its head and how much do they weigh?

Tusks are teeth and originate in the mouth, while horns are made of some stuff like keratin and originate on top (OK, in some sheep and goats at the side) of the head. Rhino horn is compressed fibre of some sort, and quite different. Antlers count as horns, I suppose, so how about the good ol' moose? Mar 09 05, 4:17 PM

Having found "antler" as a definition of "horn," Moose have the heaviest antlers of any animal on earth. www.muskokawildlife.com/animaldetails Only the males have antlers, massive flattened ones averaging 160cm across and 20kg in weight. These antlers have as many as 30 TINES (or spikes), the shape differing from animal to animal. Mature males shed their antlers once a year in November/December and replace them with new larger ones. They are formed of living tissue supplied by blood through a network of vessels covered with a soft smooth skin called VELVET. Eventually the tissue solidifies, the velvet is scraped off and the antlers become completely formed of mineralised dead matter. Their main function is for display during the mating season and dominance within the herd. The reindeer/caribou is the only deer species in which both the male and female have antlers. http://www.smouse.force9.co.uk/facts.htm Mar 12 05, 12:22 PM
