Porcellio hoffmannseggi (Commonly called the Titan Isopod) is a species of woodlouse of the genus Porcellio described in 1833. This very large species is native to Spain and the surrounding regions, particularly in the south.:[1]

Appearance and physical characteristics

P. hoffmannseggi is considered to be one of the largest terrestrial isopod species, with adults commonly growing to be over 1.5" (or 4cm) long.

There are current 4 identified sub-species of P hoffmannseggii[2]

  • Porcellio hoffmannseggi hoffmannseggi (Brandt, 1833)
  • Porcellio hoffmannseggi nemethi (Paulian de Felice, 1941)
  • Porcellio hoffmannseggi sordidus (Budde-Lund, 1885)
  • Porcellio hoffmannseggi tamarisis (Verhoeff, 1937)

Distribution and Habitat

The P. hoffmannseggi is common in the Oued Laou region of north-eastern Morocco, when compared to the distribution of other isopod species in the country.[3]

Compared to other Porcellio species, this species has been observed to prefer drier environments while kept in captivity.

In the Pet trade

P. hoffmannseggi is sometimes kept and sold as pet, popular among Isopod enthusiasts for their large size and attractive pattern. These are generally considered to be one of the largest, if not the largest, species of Isopod typically kept by pet owners in North America.

Known, cultured morphs (common slang referring to Polymorphism) of P. hoffmannseggii circulating in the hobby currently include:

  • Chocolate or Brown - A light brown variation of their typically dark grey body. This morph is thought to have been isolated from a captive culture.
  • Black - A locale of P. hoffmannseggii collected in Spain. This locale has a darker body color than the typical dark grey
  • White Out - A newly isolated morph that is light in coloration due to albinism
