List of reptiles and amphibians

Version 0.24: This article may not be up to date for the latest stable release of Crawl.

While most adventurers dream of engaging in thrilling battle with dragons, the many reptiles and amphibians of the Dungeon are still fierce foes for the aspiring hero. While they don't have any breath weapons, their bites are usually dangerous, and many of them are comfortable swimming through water. Fortunately, they are all cold-blooded, making cold damage particularly useful for fighting them.

Reptiles and amphibians are most common around the Lair and its branches, being replaced by greater, more intelligent threats later in the dungeon. The Snake Pit is, unsurprisingly, full of snakes in addition to their snakemen masters.

Amphibian Types

F Bullfrog - Although fast, these oversized frogs are more often delicacies than dangers.

F Spiny frog - Their spikes are wickedly sharp, and the poison that laces them is no picnic either.

F Blink frog - Interdimensional croakers who swarm and devour careless players while blinking incessantly.

Unique Amphibians

F Prince Ribbit - A human prince who was cursed to be a frog... and was also cursed to blink between dimensions? Regardless, he's got a vicious bite.

Lizard Types

l Frilled lizard - One of the flimsiest opponents in the game, the only thing separating them from rats is their ability to swim.

l Leopard gecko - Faster, tougher, and stronger than frilled lizards, they are among the most dangerous animals found on D:1.

l Iguana - These ill-tempered reptiles pack a bite worth keeping clear of.

l Crocodile - Unimaginative biters which hang around the Lair.

l Basilisk - Dreaded creatures of legend which petrify their prey with their gaze.

l Komodo dragon - Oversized lizards with a particularly powerful bite.

l Alligator - These swamp-dwellers are capable of surprising speed and make short work of the poorly defended with their jaws and tail.

Snake Types

"The latter lived in the country, and before his house there was an oak, in which there was a lair of snakes. His servants killed the snakes, but Melampus gathered wood and burnt the reptiles, and reared the young ones. And when the young were full grown, they stood beside him at each of his shoulders as he slept, and they purged his ears with their tongues. He started up in a great fright, but understood the voices of the birds flying overhead, and from what he learned from them he foretold to men what should come to pass." -Apollodorus (apocryphal), Library and Epitome, 1.9.11. circa 150 BC. Sir James George Frazer, translator. "A snake, with mottles rare, Surveyed my chamber floor, In feature as the worm before, But ringed with power." -Emily Dickinson, "In Winter In My Room"

S Ball python- A small constricting predator of vermin, they pose little threat to adventurers.

S Adder- Although fragile, these snakes carry sufficient venom to endanger low-level characters.

S Water moccasin- Venomous, faster and hardier than an adder, but otherwise uninteresting.

S Black mamba- Swift and evasive killers with potent venom.

S Mana viper- Mystical snakes whose bite drains magic from their victims.

S Sea snake- A brightly coloured snake that strikes with brutal venom. Fast on land and even faster in water.

S Shock serpent- Snakes that crackle with barely-contained electricity. They can store up power in order to release a mighty torrent of lightning.

S Anaconda- Enormous snakes that prefer to crush their prey to death instead of relying on venom.

S Guardian serpent- Intelligent snakes with magical skills. Moderately dangerous alone, but can teleport their allies to surround their foes.

S Lava snake- Unnatural magma-dwelling snakes that spit globs of molten stone at passing adventurers.

Unique Snake

S Aizul- A dishonoured guardian serpent who fell asleep on the job. She will happily put adventurers to sleep before blasting them with poison.

Turtle Types

t Snapping turtle - Found in the Shoals, these sturdy creatures can stretch their necks to bite from a distance.

t Alligator snapping turtle - A significantly deadlier and more durable version of the snapping turtle.

Other Reptiles

l Wyvern - Swift, winged reptiles that resemble dragonkind but are not truly draconic. They rely on their jaws instead of a breath weapon.

D Hydra - Many-headed reptilian horrors that have devoured countless incautious heroes -- as the saying goes, "Cut off one head, two more take its place..."

Unique Hydra

D The Lernaean hydra - Adventurers seeking the Swamp's rune may instead find themselves facing 27 heads of gnashing fury.
