Based on the provided reference, the snake species characterized as "usually slow-moving" is the Ovophis jenkinsi.
While the reference does not explicitly label the Ovophis jenkinsi as "lazy", its slow movement suggests a less active nature compared to other snake species. The reference also notes that while generally slow-moving, it exhibits aggression when disturbed.
It's important to note that terms like "lazy" are anthropomorphic and not scientifically accurate when describing animal behavior. The Ovophis jenkinsi's slow movement likely reflects its specific hunting strategy, metabolism, or environmental adaptations.
