Individual whales are large, but there aren’t that many individuals.

I wonder if populations have fully recovered from the whale-oil era.

Giant squid may be a bigger part of biomass than people think. I saw some estimates on sperm whale catches of giant squid and they may be eating thousands. There are far more of them than you might think, and they have a 3D living space. Sperm whale may be designed to hunt them.
