The Flora and Fauna of Barsoom

Plants

John Carter's description of Barsoomian plant life is brief and vague. In A Princess of Mars we are told that the entire surface of Barsoom is covered by an ochre, mosslike vegetation which wild herbivores live on. Trees are mentioned, but only a few varieties are described. There are a few forested regions; most notable the Kaolian Forest, the Toonolian Swamp, the Forest of Invak, and the Valley Hohr where many varieties of pre-drought plant life have survived. Flowers are mentioned occasionally, but not in detail - only that they are beautiful and of indescribable colors.

calot tree A carnivorous plant about the size of a large bush. Each branch of the calot tree ends in a set of strong jaws, with which the plant captures and consumes its prey. The tree often grows quite large, and its jaws are capable of capturing even large beasts of prey. The calot tree is apparently tropical, and thrives in the Kaolian Forest. It is often called the "tree of death" and is used by murderers and assassins to quickly dispose of their victims. It can easily be identified both by its jaw-like branches and by the piles of animal bones scattered around it.
gloresta One of the many harmless, flowering plants that grow in any depression with even a trace of moisture.
grass On occasion, Carter mentions slender, purple grass that grows to a height of eight to ten feet. This is most often seen in equatorial regions.
lawns While the surface of Barsoom is covered with a yellowish, ochre-colored, mosslike plant life, in some low-lying areas and civilized regions, lawn of reddish moss or lichen are kept. This only occurs in regions where there is sufficient moisture for the plants to become red.
man-flower Another of the bizarre carnivorous plant forms on Barsoom. The man-flower has eyespots in its blossoms and hand-like fronds for sensing and catching its prey. It lives on small insects.
mantalia A shrub or tree which grows to eight or ten feet in height. It is found in groves of varying sizes, throughout the surface of Barsoom except at the polar regions. The plant's milk-like sap is used by the green hordes and travellers of all races as an excellent food source. A single plant will give eight to ten quarts per day.
moss An ochre-yellowish moss which covers the dead sea bottoms of Barsoom, as well as the low-lying hills and plains. Herbivorous animals such as thoats and zitidars can live almost indefinitely upon this growth, deriving both sustenance and moisture from its stems and stalks.
pimalia A flowering shrub cultivated by Barsoomian gardeners, and also found growing wild in the hills and valleys of Barsoom. It produces an oil which is used as a body lotion by Barsoomian women.
skeel A tall, hardy, drought-resistant tree which is highly prized both for its large, flavorful nuts and for its wood. The wood of the skeel tree can be used for making doors, floors, furniture, and other products capable of lasting for centuries.
sompus A tree which produces a red, delicious, pulpy fruit called the somp. It is cultivated by the civilized nations of Barsoom and grows wild in tropical valleys such as the Forest of Lost Men.
sorapus A hardwood tree favored for its blossoms and nuts, and also commonly used in the making of furniture and paneling.
subterranean plants Carter mentions weird, grotesque, colorless shrubs with strange blossoms that grow along the banks of Barsoom's rare subterranean rivers and lakes.
trees Trees on barsoom rarely grow above a height of a few ads. In the Valley Dor and other sunken areas, however, there can be found trees hundreds of feet in diameter and thousands of feet tall. These vary in color from pale white to deep black, and some are azure, scarlet, or purple. The blossoms appear on the branches, and are of brilliant hues. These trees are highly prized due to their rarity.
usa A fruit tree common on Barsoom. It is hardy and requires little irrigation, and bears fruit abundantly. It is a staple food for the lower and middle classes, and for travelling armies and soldiers. Its fruit is often called the "Fighting Potato."

Animals

The animal life of Barsoom is not well documented, as John Carter describes only a few animal species. Those few that he does describe are often not given much detail; for example, he gives almost no information about common animals such as the zitidar or the orluk.

Carter tells us that there is only one mammal on the entire planet of Barsoom (PoM, 3) and that there are no hooved animals. He also implies that there are fur-bearing creatures in the south polar regions, but does not name them. The only fur-bearing creatures specifically named are the orluk and the apt.

Birds, fish, spiders, reptiles, and snakes are occasionally mentioned, but no description is given.

ape, white

A colossal, white, apelike creature standing twelve to fifteen feet in height, hairless except for a shock of white bristles on its head, and having an extra pair of limbs midway between its upper arms and its legs. The face and snout resemble an African gorilla's in appearance. White apes are tribal by nature; they are often found in mated pairs or small families. They carry clubs and some even wear skins in imitation of the leather harness of green men. They make their homes in the deserted cities of Barsoom.

hormads Ras Thavas' name for the humanoid creatures he created in his secret laboratory in the Swamps of Toonol. Each hormad was unique and grotesque; many had deformed faces and limbs.
insects Barsoom has a wide variety of insects, which range in size from only a few millimeters in length to those having a wingspan of thirty feet or more. The latter are equipped with powerful poison stings and can kill humans. No mention is made of the Barsoomian bee, but honey is known to be produced in Dusar. It is not clear if its origin is plant or animal, however.
kaldane

Strange, inhuman creatures that have guided their own evolution for millions of years, emphasizing brain power over physical prowess. Today the kaldane resembles a large disembodied head about the size of a basketball, slightly resembling an oversized crab, with large, protruding eyes, a slit nose and a ragged hole where the mouth should be. The creature's limbs, are atrophied and weak, except for its powerful chelae with which it hunts.
Kaldanes are symbiotically linked to rykors, humanoid creatures with no heads, which they use as beasts of burden, for riding, and for food.
All kaldanes have awesome powers of telepathy, and are capable of forcing lower creatures to do their bidding as long as eye contact is maintained.
Kaldanes are found only in the region known as Bantoom, where they continue their evolutionary experiment to produce the perfect brain.

malagor

A huge bird of prey, once thought to be extinct. It was used as a riding beast by Ras Thavas' hormads in Synthetic Men of Mars.

  • Size: giant
  • Society: solitary
  • Ferocity: aggressive
  • Attacks: claws, bite
  • Defenses: flight
orluk A creature found in the polar regions. It has yellow and black striped fur, which is highly valued throughout Barsoom. No clear description is given, except that it is an "elephantine beast of prey" (WoM, 9)
plant men

One of the original life forms to emerge from the fruit of the Tree of Life, the plant men have not changed or evolved in over 23 million years. An adult plant man stands twelve feet tall and is generally humanoid except that it has four short arms muscled like an elephant's trunk. Each arm ends in grasping claws which surround a leech-like mouth. It has a massive tail some six feet long that ends in a broad, flat paddle. Its body is hairless and of a ghoulish blue color. Its head is dominated by its single protruding white eye, below which is a small orifice that resembles a ragged bullet hole. The head is covered with thick, black "hair", each strand of which looks like a large earthworm. Each hair acts as an ear, and the hair appears to writhe like a mass of snakes when the creature is relaxed.
The young plant man starts as a bud in its parent's armpit, and develops into a miniature version of its parent, suspended from a cord attached to the parent's body. When the infant reaches 10 to 12 inches in length, the cord breaks and it becomes an independent creature.
Plant men move about on their kangaroo-like legs in leaps of twenty to thirty feet or more. When fighting, they leap over their opponents and use their tails as slashing weapons.

  • Size: 12 to 15 feet tall
  • Attributes: INT -12, PER +3, STR +6, DEX +4
  • Levels: 2 - 6
  • Attacks/Damage: Bite d6, Tail sweep 2d8
  • Special Abilities: Drain blood, +1 points damage per round
  • Armor: None
  • Hit Points: 26+4/level
reptiles Reptiles are rare on Barsoom, though they were common millions of years ago. The only reptiles left are found in the Swamps of Toonol and in underground caverns. They are indescribably hideous and venomous creatures.
rykor

A headless, humanoid creature used by the kaldanes as a riding beast. Millions of years ago, they were a simple burrowing creature, domesticated by the kaldanes and used as a hunting steed. The kaldanes guided their evolution and eventually took over their higher brain functions, even forcing it to walk erect. The rykor needed only its sense of taste to survive, so the head atrophied until it became little more than a mouth. The kaldane rode upon its neck, controlling the beast by tentacles that attached to the rykor's spinal column. The kaldanes bred rykors with red Barsoomian captives to improve its physical structure, producing a powerful and beautiful beast of burden which could be abandoned when killed or captured.

  • Size: 5 to 6 feet tall
  • Attributes: INT -15, PER -10, STR +2, DEX +2
  • Levels: 1 - 4+
  • Attacks/Damage: By weapon carried, typically Sword
  • Special Abilities: None
  • Armor: None
  • Hit Points: 12+2/level
silian A slimy reptile found in the Lost Sea of Korus. The therns believe that, when one of their race dies before his allotted thousand years, his soul passes into the body of a plant man. If the plant man is killed before the remainder of the thousand years (they do not tell us how they know), then his soul passes to a white ape. If the ape dies before the remainder of his allotted time, the soul is consumed by a silian.
sith

A nearly-extinct, giant hornet-like insect found in the Kaolian Forest. It resembles a hornet, but about the size of an ox. It has powerful jaws, a mighty, scorpionlike sting, multifaceted eyes, and can move with lightning speed in nearly any direction. Its venom has numerous commercial uses and is the most effective weapon against the sith itself.

  • Size: medium
  • Society: unknown (possibly hive)
  • Ferocity: deadly
  • Attacks: grapple, sting (deadly poison)
  • Defenses: wide vision, flight
snakes Carter once encounters a pit filled with loathsome, horrid, venomous creatures in the passageways beneath the Otz Mountains (WoM, 3).
sorak

A small, six-legged, catlike creature often kept as a pet by red Barsoomian women. It is not clear if it is a fur-bearing animal or a smooth-skinned one like a calot.

  • Size: small
  • Society: solitary
  • Ferocity: timid
  • Attacks: claws, bite
  • Defenses: cuteness
spiders

Barsoomian spiders are large creatures with twelve legs that grow upward from the spine. They travel by clinging to overhead strands of silk. If dislodged, they are helpless. They are very likely venomous. Their webs are often woven into strong cords and light, durable fabric that is almost impossible to tear.

  • Size: small
  • Society: family
  • Ferocity: aggressive
  • Attacks: webs, poison
  • Defenses: webs
thoat

The Barsoomian steed. Two breeds are known; a giant thoat used by green Barsoomians, and a smaller, more docile variety bred by red men. The only difference between the two is the size. The 'green' thoats

"towered ten feet at the shoulder, had four legs on either side; a broad flat tail, larger at the tip than at the root, and which it held straight out behind while running; a gaping mouth, which split its neck from its snout to its long, massive neck . . . it was entirely devoid of hair, but was of a dark slate color and was exceeding smooth and glossy. Its belly was white, and its legs shaded from the slate of its shoulders to a vivid yellow at the feet. The feet themselves were heavily padded and nailless . . ." (PoM, 3).

The rider of a thoat guides the beast exclusively by telepathic means; reins and bridle are not used on Barsoom. The green breed is notoriously bad-tempered; the red breed is more docile and controllable.

Some nations raise thoats for food as well as for riding. Albino thoats are rare, and are only kept by jeddaks.

Green Thoat

  • Size: 10 to 12 feet tall, 2200 to 3000 lbs
  • Attributes: INT -8, PER +2, STR +8, DEX -1

  • Attributes: INT -7, PER +2, STR +7, DEX -1
  • Levels: 2 - 8
  • Attacks/Damage: Bite d6, Trample 2d10
  • Special Abilities: None
  • Armor: None

ulsio

The Barsoomian rat is "a fierce and unlovely thing. It is many-legged and hairless, its hide resembling that of a newborn mouse in repulsiveness. In size and weight it is comparable to a large Airedale terrier. Its eyes are small and close-set, and almost hidden in deep, fleshy apertures. But its most ferocious and repulsive feature is its jaws, the entire bony structure of which protrudes several inches beyond the flesh, revealing five sharp, spadelike teeth in the upper jaw and the same number of similar teeth in the lower, the whole suggesting the appearance of a rotting face from which much of the flesh has sloughed away" (CoM, 12). It lives in burrows in the tunnels and dungeons beneath every city upon Barsoom. Kaldanes love to eat ulsios.

  • Size: small
  • Society: pack
  • Ferocity: ferocious
  • Attacks: bite, claws
  • Defenses: thick skin
zitidar A huge mastadonian beast of burden used by green Barsoomians. Like the thoat, it is guided by telepathic means. Some red nations, particulary Ptarth, breed them for meat and as beasts of burden. They are herbivorous and hairless, with padded feet. No clear description is given.
