The single surviving genus, Solenodon, contains two species. Solenodons now live in Haiti and Cuba. In sub-Recent and Recent times they were somewhat more widespread in distribution, but now even the Haitian and Cuban populations are declining rapidly and are in danger of extinction. Expanding human populations, the clearing of land for agriculture, and the introduction of dogs, cats, rats, and mongooses are all responsible for the decline of this group. Solenodons look like large, stout shrews. They have long snouts, small eyes, large, clawed feet and long nearly naked tails. Coat color varies from blackish to deep reddish brown. They have an incomplete zygomatic arch (maxillary and squamosal roots are present but the jugal is absent), no auditory bulla, and a nearly flat skull. Solenodons also have an extra bone, the os proboscidis, which helps support the tip of the rostrum.
The dental formula of the two existing members of this family is 3/3, 1/1, 3/3, 3/3 = 40. The anterior upper incisor is large. The second lower incisor has a deep groove. Solenodons produce toxic saliva, which is carried through this groove into the flesh of their victims. The molars are V-shaped, and the primary cusp is the paracone (zalambdodont).
The main prey of solenodons is animals (including insects), but they sometimes eat plant material as well. Solenodons live in forests or brush, and are active at night. They are apparently social, with young sometimes remaining with the parents while subsequent litters are born and raised. Solenodons walk with an awkward gait and are incapable of jumping, but can run surprisingly fast and can climb.
