The 4th Webinar of JAYP on YouTube was held, entitled "新山颯大の貝だ！虫だ！いや、介形虫だ！！ (Sota Niiyama's talk on Ostracods)". This is one of the most professional session; still, it was viewed by more than 60 people. We are happy to see that so many people have had the opportunity to get to know about Ostracods.
