With accuracy, wit, and good time Richard Armour makes his story rhyme; It's the 56th for this fun-factual author. "Strange Monsters of the Sea" (New York, McGraw-Hill, $7.95) Meet their match with glee. The deep-sea anglerfish Is a fisher of fish; The Japanese spider crab Is quick on the grab; The manta ray can vault As well as somersault. It's all in this book, Worth a second or even third look. Facts, not fiction, told with humor; Illustrated by Paul Galdone, writ by Armour.
