Impossible to tell, from the information you provide, but you indicated your animals can be in groups. Then, n is not the number of animals detected, but the number of groups. You also need to multiply by estimated mean group size in the population. (Using the default methods in the software, this isn’t simply the mean size of groups detected, because there is usually bias with larger groups being more detectable.) You also have to take care that you’re working with the same units as the software, e.g. with area as hectares.
animal population density was 13.422 or 0.02524，I want to why these results are quite different? thanks

but I also saw another calculation method of populaition density, which is
when I calculated density using above method, I found the results were total different. the detail was as follows:
form this picture,we can acquired “f(0)= 0.67635E-01 ” ,so D=93*0.67635E-01/(2*124.602)=0.02524, 93 is animal quantity, 124.602 is total L, I want to know why and its reaon?thank a lot
