Pokemon Go just went live with a new Limited Research event featuring Clamperl.
The event will last from now until 2:00 p.m. PST. During the time frame, water-type Pokemon will appear more frequently, you’ll get twice the stardust for catching water-type Pokemon and Limited Research tasks will start appearing after spinning Photo Discs at PokeStops which will award you with an encounter with Clamperl. You may event get a chance to catch a shiny Clamperl.
Here is the Pokemon Go Clamperl Research List, as found by users on The Silph Road Subreddit. Each of these tasks will award you with a Clamperl and after acquiring one from a PokeStop you can complete it at any time even after the event ends.
