The Hispaniolan solenodon (Solenodon paradoxus) is a venomous insectivorous mammal resembling a shrew, endemic to the Caribbean island of Hispaniola (Dominican Republic and Haiti). It inhabits moist forests, shelters in burrows or under logs, and feeds primarily on arthropods, worms, molluscs and small vertebrates. Crepuscular and nocturnal, it moves in a zigzag gallop and produces varied vocalizations for communication and defense.

The Amblysomus hottentotus, commonly known as the Hottentot Golden Mole, is a small insectivorous mammal endemic to southern Africa. It is characterized by its silky, golden-tinged fur, giving it a unique appearance. Adapted to a subterranean lifestyle, it has powerful forelimbs and robust claws for efficient digging. Its eyes are covered by skin, as vision is of little use in its underground habitat. It primarily feeds on insects and small invertebrates it finds in the soil. Although elusive, it plays a crucial role in the ecosystem by aerating the soil and controlling insect populations.

The Hermann’s tortoise is a Mediterranean terrestrial tortoise, 15–20 cm long, with a yellowish carapace patterned with black markings. Endemic to the shrublands and garigues of southern Europe, it also inhabits open woodlands and rocky grasslands, feeding on leaves, flowers, and small fruits. During breeding (May–June), males engage in head-bobbing displays and scrape the soil before nesting.

The Hawksbill sea turtle is a widely recognized species of sea turtle, known for its shell's overlapping, tile-like scales, from which it gets its name. It is primarily found in the warm tropical and subtropical waters of the Atlantic, Indian, and Pacific Oceans. This marine reptile is primarily carnivorous, feeding on jellyfish, fish, and crustaceans. The Hawksbill is particularly vulnerable due to habitat loss from pollution and illegal collection of its shell. It is also threatened by illegal fishing and loss of nesting beaches.

The horned viper, scientifically known as Vipera ammodytes, is a venomous snake found primarily in the Balkans and parts of Southeast Europe. It is distinguished by its triangular head and the unique horn-like structure on its snout. Its coloration ranges from gray to brown, with zigzag patterns along its back, providing excellent camouflage in its natural rocky and dry habitats. This species is typically found at altitudes from 0 to 2000 meters. Although its venom can be dangerous to humans, bites are rare and usually occur only when the snake feels threatened.
