A large close relative of C. elegans is slow-developing but not long-lived.

“C. inopinata females were longer-lived than wild-type C. elegans hermaphrodites at 25°C, with a median total lifespan that was four days higher [...] However, C. inopinata females were only marginally longer lived than C. elegans (fog-2) pseudo-females.”
