“Kingdom of the Blue Whale” (8 p.m., National Geographic): Here’s a whale of a subject! In “Kingdom of the Blue Whale,” National Geographic Channel devotes two hours to the largest creature that ever lived on Earth — an animal that dwarfs the hugest dinosaurs and weighs as much as 25 full-grown elephants. Among the mysteries of these graceful leviathans: Where do they produce their young? The film follows a team of scientists who attempt to find the blue whales’ calving and wintering grounds. It also features computer graphics of the developing fetus and employs a so-called Crittercam: an integrated camcorder and data-gathering system suction-cupped to the whale’s back, which captures footage of krill-snacking from the whale’s point of view. Narrated by Tom Selleck.
