He was the younger brother of French naturalist and South American explorer, Alcide d'Orbigny. At the National Museum of Natural History in Paris, d'Orbigny identified many of the flowering plant species returned to France from his brother's natural history collecting journeys through South America.

The large harp or major harp (Harpa major) is a species of large predatory sea snail, a marine gastropod mollusks in the family Harpidae, the harp snails and their allies. The size of the shell varies between 6 cm and 13 cm. The large harp has a long siphon, a large mouth and a very large foot in proportion to its shell, which it uses to hunt its prey. A voracious nocturnal predator of benthic crustaceans on sandy bottoms, it can prey on crabs as large as itself. Harpa major occurs off East Africa, Tanzania, Mozambique, the Mascarene Basin; off Hawaii.
