Perhaps this pulse functions in echolocation. Solenodons may fight each other on first meeting, but eventually they establish a dominance relationship and live together in captivity in relative harmony. The litter size is one to three. The offspring of two successive litters may stay with the parents. Up to eight animals have been found in one burrow. . . .
Nothing is known about the gestation period or the birth process. . . .
The life expectancy of the solenodon is not known. One in the Breslau Zoo reached an age of six and one half years. A Cuban solenodon which arrived in the Philadelphia Zoo in 1886 survived for more than five years. Both species of Solenodon are listed as endangered by the IUCN and the USDI . Recently, S. cubanus has been discovered in many parts of eastern Cuba, though it is rare.
