Bill (born 1998)
Bill arrived at the Marine Science Center from the Dolphinarium Harderwijk, The Netherlands. He attracts attention by his black appearance and can be aggressive as well as very timid. He often shows his enormous power when rearing up on land or at the water surface if he splashes through the water. He has shown his excellent working attitude in acoustical experiments in which he is also currently taking part. He also participated in many visual experiments in which he learnt the visual acuity task easily. However he almost failed in a visual matching experiment.
