Today the rulers of the sea are fish , but in this case , we're talking about whales.Whales will probably go extinct , especially after a mass extinction , but what would fill their niche?Maybe birds , maybe reptiles , maybe some fish or even again mammals , who knows!So , what do you think?My i ideas are:Marine varanoids in the Indian ocean , but not the African side.
Marine descendants of the saltie croc.One can reach 12 m,They inhabit Indonesia and north Oceania.
Flightless birds in Antarctica.
Marine , palaeophid like boids from the coast of South America.

Do you mean all cetaceans or only whales? If all cetaceans, I think dolphins and such will be taken over by sealions and/or seals, who will probably also take over most of the whale niches. In Antarctica penguins have a good chance of becoming fully aquatic, and in Oceania we'll probably see gigantic, salt water crocodile descendants.

Maybe other seabirds can take over some niches, like puffins around Iceland, or cormonants in Japan (being endemic to a small particular area ofcourse). Other mammal participants are sea otters, or with an even langer extinction, highly derived forms of beavers.

Possible invertebrates include squids and sharks.

Not birds!Boids (the family of boas and anacondas).

I was talking about all cetaceans.Marine monitors similar to early mosasaurs also seem possible.Your ideas are good and may be used , but those cetacean seals would be restricted to small areas and would be fairly primitive since the mass extinction made them really rare.Maybe some large otters could inhabit the northern part of the Atlantic ocean , but the pelagic niches would be filled by fish.What about filter feeders?I had an idea of giant , filter feeding groupers , up to 15 m long and that inhabit the regions of Oceania and Indonesia , plus the city ATS of Asia (not the east).

They can also be marine birds
