Is the Otter Dangerous?

Although it is not common for otters to hunt birds such as gulls,
they are opportunistic feeders, which means they can hunt
and eat a seagull if other food sources are scarce or if
a convenient opportunity arises (say, for example, someone
be feeding Them!) Being opportunistic feeders allows people to
otters survive and thrive in a variety of environments and under
different conditions, as they can readily exploit any source of
food available.
