Charles Lucien Bonaparte
May 24, 1803 – July 29, 1857. Author abbreviation: Bonaparte

Charles Lucien ("Carlo Luciano") Bonaparte was French zoologist specialized in ornithology and ichthyology. He also studied amphibians and reptiles and is the author of Ursini's viper, Vipera ursinii. Bonaparte was the son of Lucien Bonaparte and Alexandrine de Bleschamp, and a nephew of Emperor Napoleon. Born in Paris, he was raised in Italy. After getting married to Zénaïde Bonaparte, he and his wife left for Philadelphia in the United States to live with Joseph Bonaparte, father of Zénaïde. Before leaving Italy, Charles had already discovered a warbler new to science, the moustached warbler (Acrocephalus melanopogon), and on the voyage he collected specimens of a new storm-petrel, Oceanites oceanicus. On arrival in the United States he presented a paper on this new bird, which was later named Wilson's storm petrel (after Alexander Wilson).

At the end of 1826, Bonaparte and his family returned to Europe. He visited Germany, where he met Philipp Jakob Cretzschmar, and England, where he met John Edward Gray at the British Museum, and renewed his acquaintance with John James Audubon. In 1828, the family settled in Rome. In Italy, he was the originator of several scientific congresses, and lectured and wrote extensively on American and European ornithology and other branches of natural history. Between 1832 and 1841, Bonaparte published his work on the animals of Italy, Iconografia della Fauna Italica. He had also published Specchio Comparativo delle Ornithologie di Roma e di Filadelfia (Pisa, 1827), presenting a comparison between birds of the latitude of Philadelphia and Italian species. He created the genus Zenaida, after his wife, for the mourning dove (Zenaida macroura) and its relatives. He was elected a member of the American Antiquarian Society in 1845.

In 1850, Bonaparte and his family of wife and twelve children moved to France, and he made Paris his home for the rest of his life. In 1854, he became director of the Jardin des Plantes. In 1855, he was made a foreign member of the Royal Swedish Academy of Sciences. He published the first volume of his Conspectus Generum Avium before his death, the second volume being edited by Hermann Schlegel. Lucien Charles Bonaparte died in Paris at the age of 54.

Common Hermit Crab

Pagurus bernhardus

Some facts on this crab:

Carapace length: Up to 4.5 cm.

Body length: Up to 8 cm.

Habitat: Rocky and sandy substrata from mean tide level to 140 m. depth.

Range: European and North American coastal waters.

Diet: Mainly detritus (decomposing organic matter).

First described: By the Swedish naturalist Linnaeus in 1758, who originally named it Cancer bernhardus.


Pagurus bernhardus chooses its home and carries it on the back wherever it goes. The body of this hermit crab lacks a hard, protected carapace. Without a shell it is extremely vulnerable to predators, so it searchs for an empty snail shell (for example whelk or periwinkle) and adopts it for an home. The availability of suitable shells is often limited, which leads to intense competition among the crabs for shells of the proper size and condition. This crab often grows in the shell the sea anemone Calliactis parasitica which helps to protect the crab with its nettling tentacles, and in exchange enjoys the crab's food. Pagurus bernhardus, which is a reddish or brownish crab, walks on its second and third pairs of legs and uses the strongly reduced fourth and fifth pairs to grip the central column of the snail shell and to circulate breathing water. The genus Pagurus contains some 180 species and belongs to the hermit crab family Paguridae, along with 79 other genera.
