As far as dragons go, Silkspanners didn't look like the most able flyers. With their inflated gullets and wispy web wings, they're at the mercy of the wind. [src]

The Silkspanner is a medium-sized Mystery Class dragon that first appeared in Burning Midnight.

Official Description

This nomadic spider-dragons island hop across the Archipelago by weaving web wings between their six arms and ballooning their gullets with air.
  Dragons: Rise of Berk  

Physical Appearance


Silkspanner Egg.png

In Rise of Berk, a Silkspanner egg is oval, full of bumps, and has a greenish color. It has several spikes for protection on the upper half. In addition, it is covered in a large web, presumably by the parents. It is unknown whether it is secreted by the egg as a protection against possible predators.

Hatchling to Adult

The Silkspanner is a six-legged wingless dragon that somewhat resembles an iguana. It has four eyes; a bigger pair in front and a smaller pair in the back. It has chelicerates, similar to a spider's, and its body is green with yellow underbelly and light purple legs. It has a row of long sharp spines along its back and a long tail, as well as long thin claws and a small membrane between its toes. It also possesses numerous thin spines on its head and under its chin.

Titan Wing

A Titan Wing Silkspanner is not very different from the adult form. The most notable change is that there are many more spikes on its back, head, and legs. It turns sea blue in color, with pale white belly.



Spitting Silk

Just like real life spiders, Silkspanners can shoot silk to create webs and trap their prey in them. They can launch these silks from their mouths and their rear ends. The webs are so powerful that not even the strongest of dragons can break through it using brute force.


Silkspanners are able to climb vertical rock walls and trees using their long claws. They can even climb facing downwards without any difficulties.

Wingless Flight


Silkspanners are able to fly and glide for relatively short distances (i.e. between islands, but not across the archipelago) by weaving webbing between their three pairs of legs. With these, they are able to catch the wind currents. This leaves them somewhat vulnerable to the whims of wind direction. Additionally, they fill their stomachs with air to add some buoyancy, according to Dragons: Rise of Berk.

Poison Removal


Baby Silkspanners have demonstrated the ability to suck out the toxic component of the dragonvine plants that infect both dragons and humans in a seemingly painless process. It is not divulged if adult Silkspanners can also do this.

Strength and Combat

Silkspanners appear to be strong dragons, for the hatchlings are able to use their webbing to grab and lift full-grown humans with minimal effort, and two of them are able to carry Bayana without any signs of struggle.

Floating on Water

In order to cross over water when the conditions are not favorable for gliding, Silkspanners are able to float on the surface using strands of fine silk, as mentioned in Dragons: Rise of Berk.

Behavior and Personality

Silkspanners are highly territorial dragons and are protective of their eggs towards any they those consider as intruders. However, they will come to aid those that are being affected by their primary food source: dragonvine, and it is their species’ role to make sure that the aforementioned toxic plants don’t spread to other parts of the world.


Graphic Novels


Main article: Bayana's Silkspanners

The Riders, Valka, Gobber, and Eret trap themselves in a cave as protection from wild dragons attacking them so they can rest for a bit. After a short while, Hiccup and Toothless blast their way out of the cave, revealing that the wild dragons surrounding the cave are Silkspanners. Toothless attempts to assert his dominance as the Alpha Dragon, but the Silkspanners are too frenzied to follow his commands. Eventually, the Riders manage to scare off the Silkspanners, but not before Hiccup snatches an arrow that is lodged on one of them. Hiccup believed that the Silkspanners had encountered the Dragon Hunters, which caused them to become hostile towards humans.

Some of the Riders begin to search for the Silkspanners as they come across an island where the Silkspanners originate from, one that is infested with the deadly dragonvine plant. It is revealed that Bayana and his tribe drove the Silkspanners from the island in order to grow dragonvine to defend themselves. As the Riders continue their search, Hiccup and Gobber conclude that the Silkspanners need heavy gusts of wind to help in their journey, and it is not long for them to come across an island that has become the nest of a female Silkspanner and her hatchlings. The Riders begin to fend off the attack, but Toothless is unknowingly ambushed by a dragonvine that was secretly placed in his saddle by Bayana's tribesmen. Before Hiccup can fight off the approaching Silkspanners, Fishlegs and Valka arrive on Cloudjumper to leave the dragons be, for their purpose is to feed on the dragonvine and free Toothless in the process.

Hiccup and the Riders then return to the island where dragonvine is continuously sprouting out of control and allow the Silkspanners to feed on them, preventing the plant from spreading to other islands. Upon this realization, Bayana and his tribe decide to coexist with the Silkspanners.


Dragons: Rise of Berk

The Silkspanner was introduced in this game in a Dreadfall update.


  • Bayana and his tribesmen refer to the Silkspanners as 'Anansi'. Anansi is a character in mythology that is sometimes a man and sometimes a spider or a mix of both, and represents wisdom. Anansi figures into the Akan culture occupying the Gold Coast region of Africa, in what is present-day Ghana.
  • Next to the Red Death the Silkspanner is the only other dragon to have more than two eyes on its head.
  • The Silkspanner's ability to glide is similar to that of real-life flying lizards, flying squirrels, sugar gliders, and colugos.
