Water spirits
What lives in the water differs less between traditions than what you can do about it — and the difference is a question of scale.
The water spirits on this site
Four figures carry this tag, from two traditions, and putting them side by side exposes something that neither tradition shows on its own.
In Slavic belief, a water spirit owns a particular body of water. The vodyanoy holds one river, one millpond, one stretch of marsh. The rusalka belongs to the water she died in, or to the week in early June when the rusalki leave it. The swamp kikimora is attached to her own patch of wet ground. These are local proprietors with jurisdictions you could walk the edge of in an afternoon.
In the Visayan material the water spirit is the sea and the sky together. The Bakunawa lives in the ocean, or the underworld, or above — the sources do not agree and do not need to, because it is not holding a location. It is eating the moon.
That difference in scale determines everything about how people dealt with them.
You can negotiate with a millpond
Because the Slavic water owner holds a specific property, there is a relationship available, and the record is full of its terms. Fishermen poured melted butter or oil into the river. Beekeepers sacrificed the first swarm of the season, and at midnight on the feast days of Saints Zosimus and Sabbatius dipped a honeycomb into the water beside the mill. Building a mill required a sacrifice outright. A miller who neglected the arrangement could expect his dikes opened.
Read as economics this is entirely rational. A mill is a large investment placed deliberately in the path of a destructive force, and the force will eventually destroy it. The vodyanoy gives that risk an owner, a price and a procedure. You cannot negotiate with a spring flood, but you can negotiate with a landlord — and the calendar of payments turns an unmanageable danger into an annual expense.
You cannot negotiate with an eclipse
The Bakunawa has no terms. Nobody leaves butter for it. The entire recorded response is noise: people went outdoors during an eclipse and beat pots, drums, bells and anything metal until it let the moon go. Children sang. Some accounts have music played gently to put it to sleep instead, which is the closest the material comes to a technique rather than a protest.
Fr. Tomas Ortiz, recording the rite in 1731, found that his informants disagreed about what was eating the moon — a dragon, a tiger, a crocodile. They agreed completely about what to do. When the thing is that large, its identity becomes negotiable and the procedure does not.
The dead and the owners
A second division cuts across the first, and it is about what the spirit is.
The rusalka is, in the dominant reading, a revenant: Dmitry Zelenin placed the rusalki among the unclean dead, the souls of young women who drowned or were drowned. Her water is where something happened to a person.
The vodyanoy and the Bakunawa are not dead anything. They are proprietors and cosmological actors respectively — the water is theirs, not their grave.
The kikimora sits awkwardly between, which is why she is here at all: her swamp form is the leshy's wife and behaves like a wild spirit, while her house form is a domestic one. She is tagged for the swamp, and the tag is honest about being half the figure.
Worth noting that the categories blur in the sources themselves. The vodyanitsa, the vodyanoy's female counterpart, is frequently conflated with the rusalka, and in some beliefs she is specifically a baptised drowned girl. Where a tradition is not tidy, we do not tidy it.
What the water means
One last pattern, offered as an observation rather than a conclusion.
In all four cases the water is a boundary that people have to cross anyway. Fishermen work it. Millers build on it. Farmers ford livestock through it. Bathers and children go into it, and in the Visayas the moon passes over it. None of these figures guards somewhere people could simply avoid.
So the lore is not avoidance lore. It is crossing lore: cross yourself before bathing, teach the children a rhyme, make the sign of the cross over the ford, pour the butter, beat the pot. The spirits mark the places where ordinary work is dangerous, and the practices are what let the work continue.
