The guineafowl (sometimes called guineahen) are a family of birds in the Galliformes order, although some authorities (for example the American Ornithologists' Union) include the guineafowl as a subfamily, Numidinae, of the family Phasianidae. The guineafowl are native to Africa, but the Helmeted Guineafowl has been domesticated, and both feral and wild-type birds have been introduced elsewhere.

The guppy (Poecilia reticulata), also known as the millionfish, is one of the most popular freshwater aquarium fish species in the world. It is a small member of the Poeciliidae family (females 4–6 centimetres (1.6–2.4 in) long, males 2.5–3.5 centimetres (1.0–1.4 in) long) and, like all other members of the family, is live-bearing.

Halibut is a flatfish, genus Hippoglossus, from the family of the right-eye flounders (Pleuronectidae). Other flatfish are also called halibut. The name is derived from haly (holy) and butt (flat fish), for its popularity on Catholic holy days. Halibut are demersal fish which live in the North Pacific and the North Atlantic oceans. They are highly regarded food fish.

The hammerhead sharks are a group of sharks in the family Sphyrnidae, so named for the unusual and distinctive structure of their heads, which are flattened and laterally extended into a "hammer" shape called a "cephalofoil". Most hammerhead species are placed in the genus Sphyrna while the winghead shark is placed in its own genus, Eusphyra. Many not necessarily mutually exclusive functions have been proposed for the cephalofoil, including sensory reception, maneuvering, and prey manipulation. Hammerheads are found worldwide in warmer waters along coastlines and continental shelves. Unlike most sharks, hammerheads usually swim in schools during the day, becoming solitary hunters at night. Some of these schools can be found near Malpelo Island in Colombia, Cocos Island off Costa Rica, and near Molokai Island in Hawaii. Large schools are also seen in southern and eastern Africa.

Hornets are the largest eusocial wasps; some species can reach up to 5.5 cm (2.2 in) in length. The true hornets make up the genus Vespa and are distinguished from other vespines by the width of the vertex (part of the head behind the eyes), which is proportionally larger in Vespa and by the anteriorly rounded gasters (the section of the abdomen behind the wasp waist). The best known species is the European hornet (Vespa crabro), about 2–3.5 cm in length, widely distributed throughout Europe, Russia, North America and Northeast Asia.

Hummingbirds are birds that comprise the family Trochilidae. They are among the smallest of birds, most species measuring in the 7.5–13 cm (3–5 in) range. Indeed, the smallest extant bird species is a hummingbird, the 5-cm Bee Hummingbird. They hover in mid-air by rapidly flapping their wings 12–80 times per second (depending on the species). They are known as hummingbirds because of the humming sound created by their beating wings, which sometimes sounds like bees or other insects. To conserve energy while they sleep or when food is scarce, they have the ability to go into a hibernation-like state (torpor) where their metabolic rate is slowed to 1/15th of its normal rate. When the nights get colder, their body temperature can drop significantly and thus slow down their heart and breathing rate, thus burning much less energy overnight. As the day heats back up, the hummingbirds' body temperature will come back up and they resume their normal activity. They can fly at speeds exceeding 15 m/s (54 km/h; 34 mph); they are also the only group of birds with the ability to fly backwards. Individuals from some species of hummingbirds weigh less than a penny.

Husky is a general name for a type of dog used to pull sleds in northern regions, differentiated from other sled-dog types by their fast pulling style. They are "an ever-changing cross-breed of the...fastest dogs". The Alaskan Malamute, by contrast, is "the largest and most powerful" sled dog, and was used for heavier loads. Huskies are used in sled dog racing. In recent years companies have been marketing tourist treks with dog sledges for adventure travelers in snow regions as well. Huskies are also today kept as pets, and groups work to find new pet homes for retired racing and adventure trekking dogs.
