"Korak, Son of Tarzan, Croc Fighter" from Korak, Son of Tarzan #47 (DC, 1972) by Len Wein and Frank Thorne
A license (and numbering) inherited from Gold Key, DC sent the Son of Tarzan into more fantastical realms than his dad, and produced, from what I've seen, some very good jungle action comics. The book went from 46 to 59 before turning into Tarzan Family (Families aren't just for Batman and Superman!) where, naturally, Korak's strip continued. Something to hunt down, I think.
