These Camel like animals roam the desert in small herds. The desert folk have uses for these creatures.
Ka’tshar are very similar to ants with one exception. They are about 6" long.
The Californian Sea Otter, as a species, eats about 30 different types of food found throughout its range. Each individual otter, however, will only eat 3 or 4 of these foods - those it was fed by its mother as a child. It will not eat the others even if failure to do so means it would starve. Maybe other, possibly larger and more dangerous creatures and monsters, have similar habits.
