The family Solenodontidae consists of rare, small, nocturnal mammals known as solenodons, which are native to the Caribbean islands of Hispaniola and Cuba. These primitive insectivores are notable for their elongated snouts, flexible noses, and venomous saliva delivered through grooves in their lower incisors—a unique feature among mammals. Solenodonts have a shrew-like appearance and primarily feed on insects, worms, and small invertebrates, using their sensitive snouts to probe soil and leaf litter. They exhibit solitary and nocturnal behavior, nesting in burrows or dense vegetation. Due to habitat loss, predation by introduced species, and low reproductive rates, solenodons are considered endangered, making them a critical focus of conservation efforts.
