DescriptionPisa armata grows to a length of {{convert|40|mm}}.[2] Its carapace is roughly triangular, with two prominent rostral spines, which are parallel in males, but divergent in females.[2] The carapace is brown, but is often covered in seaweed, sponges or anemones.[2]DistributionPisa armata is found in the eastern Atlantic Ocean from around the Isle of Man as far south as Angola, as well as in parts of the Mediterranean Sea.[3] It lives at depths of {{convert|1|-|108|m}}.[3]EcologyPisa armata is parasitised by a rhizocephalan barnacle. Although initially considered to be the same species that attacks other crabs such as Carcinus maenas, experiments in the 1960s demonstrated that the two were different species, Sacculina carcini on C. maenas, and Sacculina gibbsi on P. armata.[4]References1. ^{{cite WoRMS |author=Charles Fransen & Michael Türkay |year=2011 |title=Pisa armata (Latreille, 1803) |id=107353 |accessdate=January 15, 2012}} 2. ^1 2 {{cite book |author=Andrew Campbell |year=2005 |title=Philip's Guide to Seashores and Shallow Seas of Britain and Northern Europe |publisher=Philip's |isbn=978-0-540-08747-1 |chapter=Pisa armata (Latreille) |page=235}} 3. ^1 {{cite journal |author=R.
