The Fire Fly mini propane flame unit is great for applications that require a real flame effect. Available in 1/4 or 1/2 systems, the units provides a remotely cue-able column (or fireballs) of fire 6'-15' tall (depending on units used) with a host of safety features like positive flame recognition, pilot light sensing, and an emergency shut off valves.
Primates still do, but many, if not most, mammals do not. Horses, deer, cows and many other mammals have a reduced number of digits on their forelimbs and hindlimbs. Primates also retain other generalized skeletal features like the clavicle or collar bone.
Horses and ponies are genetically two different species. There are horse-sized ponies, and pony-sized horses, but the genetics are what tells them apart, not the size. A miniature horse, for example, is very small and looks like a pony, but genetically, it is a horse.
