The size of a larkin ranges between the size of a hand and a small melon. They are somewhat similar to cremlings in appearance, although, unlike the cremlings' crabbish face, the larkin have a small face, like that of an 斧狐犬, with a snout, mouth, and shimmering eyes of solid silver, as well as wings that folded out of their backs. Their wings are strong enough that they can fly, at least in small distances.
The most outstanding feature of a larkin is their ability to suck 飓光 out of a Surgebinder at will. The Stormlight can be seen streaming from the Surgebinder towards the larkin's mouth as it is drinking in the Stormlight. It is unknown if the larkin can suck Stormlight only from a Surgebinder or if the Surgebinder can resist the larkin.
