Gentaur [Public domain] via Wikimedia CommonsThe Watanabe rabbit is an inbred strain developed from the New Zealand White breed commonly found in laboratories. New Zealand Whites are relatively large rabbits: adult males can weigh 8–10 lb and females up to 12 lb. They have muscular bodies, large hind feet, thick fur and long ears that stand straight up. Because of albinism, their fur is snowy white. The shorter hairs on their ears allow the pale pink of their skin to show through, and their eyes range in color from light pink to deep ruby red.
