#  How to get fish names downstream from family names using taxize
## load libraries
install.packages(c("plyr","taxize"))
library(taxize); library(plyr)

## get taxonomic serial numbers from ITIS for these two fish families
tsns <- get_colid(c("Anostomidae","Curimatidae"))

## Use the function `downstream` to get all species (specified by the `downto` argument) in these two families
out <- downstream(tsns, downto="Species")
