Kind of, but one would be enough to kill death angels. Future predators would adapt to feed on them. A being relying on its hearing against a perfect stalker with human level intelligence. They would imitate the echolocation frequency of death angels, maybe even make noise intentionally to prompt them to open their heads, then either crank up the echolocation to paralize the deatha ngel or straight up stab or bite through its fleshy head below. They are almost perfectly designed to prey on death angels.
