Òtítọ́

This spider is one of the few species known to attack nearly almost all approaching males, which biologists consider unusual because it can stop mating from succeeding.1

The raft spider can stay hidden underwater for several minutes.1

Females will sometimes eat the male before, during or immediately after mating.1

Males signal their presence to the female by using vibrations on her dragline, which may help them avoid being attacked.1
