Gaboon Viper
- Scientific name: Bitis gabonica
- Type of animal: Reptile
- Family: Viperidae
- Where found: Sub-Saharan Africa
- Conservation status: Vulnerable
The Gaboon Viper is a highly-venomous African snake found in rainforests and savannas south of the Sahara Desert.
The species has the longest fangs of any venomous snake. These lethal weapons reach lengths of up to 5 cm / 2 in., and are used by the snake to inject venom into its prey, which consists of small to medium-sized mammals and birds.
Although the Gaboon Viper’s venom is deadly to humans, the snake is not particularly aggressive and will only attack when provoked.
With an average length of 1.2 meters / 3.9 feet, the Gaboon viper is the largest member of the Viperidae family. It is not uncommon for this snake to reach 2.2 m / 7.2 feet and to weigh over 10 kg / 22 lbs.
The Gaboon viper is viviparous (i.e., it gives birth to live young). Females give birth to around 35 offspring after a 7-month gestation period. The young snakes are independent from the moment they are born and receive no parental care.
The Gaboon viper has no known predators. Even monitor lizards known to feed on venomous snakes will stay away from this apex predator.

Galápagos Penguin
- Scientific name: Spheniscus mendiculus
- Type of animal: Bird
- Family: Spheniscidae
- Where found: Galápagos
- Conservation status: Endangered
The Galápagos penguin is one of the smallest species of penguin, and the only penguin species found north of the equator. The species is endemic to the Galápagos Islands of Ecuador.
This small penguin is currently endangered due to its very limited range and threats from both human disturbance and climate change.
The Galápagos penguin is entirely carnivorous, feeding exclusively on small fish and crustaceans. It hunts in groups, chasing its prey underwater before capturing it from below.
The Galápagos penguin forms monogamous pairs that breed all year round. Mortality is high among individuals of all ages due to predation by sharks, fur seals and hawks, as well as by introduced predators such as dogs, cats and rats.

Garter Snake
- Type of animal: Reptile
- Family: Natricidae (Colubridae)
- Where found: North America
- Conservation status: Least Concern
There are 35 species of garter snake, all of which are found in North America (including Central America). Together, they make up the genus Thamnophis, which is part of the family Natricidae.
Garter snakes are some of the commonest snakes in North America. Their success is due in part to their great adaptability; garter snakes are able to live in a wide range of habitats.
Once thought to be non-venomous, garter snakes are now known to have mild toxins in their saliva. This causes paralysis in their prey, making it easier to swallow. These toxins are harmless to humans.
If threatened, garter snakes emit a foul-smelling secretion from their anal glands.
Garter snakes in Canada are known to hibernate underground in large numbers, emerging together in the spring.

Gentoo Penguin
- Scientific name: Pygoscelis papua
- Type of animal: Bird
- Family: Spheniscidae
- Where found: Antarctica, Subantarctic islands
- Conservation status: Least Concern
The Gentoo penguin is the third-largest penguin species, and the fastest underwater bird; the species is capable of reaching speeds of 36 km / 22.4 miles per hour when hunting. Like all penguin species, the gentoo is carnivorous, feeding on fish, krill and crustaceans.
As well as being found on the Antarctic Peninsula of Antarctica, the gentoo penguin is found on several Antarctic and Subantarctic islands between 45° and 65° S.
This penguin has the typical “countershading” coloration shared by all penguins. This provides camouflage from both predators and prey. The white undersides match the sky when the penguin is viewed from below, while their black dorsal side blends in with the ocean floor when the penguin is viewed from above.
The Gentoo penguin is sexually dimorphic, with males being larger than females. The breeding season lasts from June until November, and the Gentoo forms monogamous pairs each season. Both sexes take turns incubating their eggs and caring for their young.

Giant Clam
- Scientific name: Tridacna gigas
- Type of animal: Bivalve
- Family: Cardiidae
- Where found: Indian and Pacific oceans
- Conservation status: Vulnerable
The Giant Clam is the world’s largest bivalve mollusk. Its shell that can reach widths of up to 1.5 m / 4ft 11in., and individuals can weigh more than 250 kg / 551 lbs.
As an adult, the giant clam attaches itself to the seabed and is sessile (unable to move). Unable to flee if threatened, the only defense mechanism the mollusk has is to retract its mantle and close its shell.
Despite being sessile, the Giant Clam reproduces sexually via a mechanism called “broadcast spawning” in which eggs and sperm are emitted into the sea. Fertilization occurs by chance in the open ocean.
After hatching, the larvae are free-swimming for around a week. After finding a suitable habitat, they affix themselves to a surface from which they will never move.
Although the giant clam uses a siphon to filter out water and consume plankton and other microorganisms, most of its sustenance comes from the symbiotic relationship it has with the billions of photosynthetic algae that live in its mantle.

Goose
- Type of animal: Bird
- Order: Anseriformes
- Where found: All continents except Antarctica
Geese, together with ducks and swans, belong to the family Anatidae. Due to heavy hybridization, it is unclear exactly how many goose species exist.
The collective noun for a group of geese is a “gaggle”.
All wild goose species are monogamous (they mate for life). Domestic geese, however, exhibit polygamy, which is convenient for breeders who raise the birds for commercial purposes. A female goose incubates her eggs for 22 - 40 days while the male stands guard next to her.
Geese are extremely territorial, especially during the breeding season and while nesting. For this reason, geese make good “guard dogs”, honking loudly when strangers approach.
All geese species are omnivorous, but plant matter makes up the bulk of their diet.

Great Hammerhead Shark
- Scientific name: Sphyrna mokarran
- Type of animal: Fish
- Family: Sphyrnidae
- Where found: temperate waters worldwide
- Conservation status: Critically Endangered
The great hammerhead shark is the largest of the 10 recognized species of hammerhead shark. This predatory fish, which reaches lengths of over 6 meters (20 ft.), is found in temperate waters worldwide.
The great hammerhead shark’s hammer-shaped head is known as a “cephalofoil”. The cephalofoil gives an improved field of vision, enabling the shark to see above and below it.
The shark’s cephalofoil also provides a wide area for the shark’s electroreceptors. These organs enable the shark to sense the electrical fields produced by the muscles of its prey.

- Scientific name: Cavia porcellus
- Type of animal: Mammal
- Family: Caviidae
- Where found: Worldwide
- Conservation status: Domestic
The guinea pig is a rodent first domesticated in South America over 3,000 years ago, originally as a source of food. After the Spanish colonization of South America, the guinea pig began to be selectively bred as a household pet, and eventually became globally distributed.
There are five wild guinea pig species in different parts of South America, four of which are listed by the IUCN as species of least concern. The Santa Catarina’s guinea pig is listed as critically endangered and it is only found in a small area of Brazil.
The guinea pig is one of the largest pet rodents, weighing between 0.5 - 1.5 kg / 1.1 - 3.3 lbs. With a lifespan of up to 14 years, it is also one of the longest-lived.
The highly-social nature of the Guinea pig can lead to problems; males establish social hierarchies and can get very aggressive with each other.
