show a small but gradual decrease in importance over time as measured by NISP (6th to 8th rank), but exhibit the reverse trend when assessed by MNI, where they jump from being a relatively unimportant taxon in Phase II and III to 6th place in Phase IV.
All are covered with spines that are either rigid as in the burrfishes or erectile as in the porcupinefishes
