The plesiosnatch replaced its ancestor, the lurking snatch in the Jujubee Ocean. Over time the necks of the snatches got longer, allowing the snatch a higher flexibility and range while hunting. The two corners in its mouth from its ancestor evolved into two fang-like extensions. On the head there are two pairs of eyes, while the third one remained at the beginning of the neck to allow the snatch vision under water either for prey or for its hunters like the snark. Of course it can still change its colours for example imitating a silverling swarm on the back for luring seaplents or imitating a swarm of swarmers for attracting silverlings, flying silverlings and all sorts of small swarmer-vores.
