Myrka
The Myrka is a large species of reptile that was used by the Silurians for back-up. They were genetically modified from a deep-sea creature.
Myrkas have a large, flat head with large eyes and two sea devil-like fins. Under their chins they have strange kelp growths. They have two arm-like appendages and four legs. Myrkas have a powerful electric attack which is transmitted through their skin. They can kill a human with this power and can also electrify metals. On the other hand, since the Myrkas were created from a deep-sea creature, they are very susceptible to bright lights.
Myrkas were used in both The Scales of Injustice and Warriors of the Deep by the Silurians to try to defeat the humans.
