Of the invertebrates in the U.S., approximately 200 are on the endangered species list. The IUCN also lists 36 invertebrate subspecies as endangered. [3] While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed."[4].
