Marco (born 1982)
Marco is the oldest seal of our group. He spent many years of his life at the Wilhelma in Stuttgart and he finally arrived at the Marine Science Center with a detour over the Dolphinarium Harderwijk, The Netherlands. For many years Marco had bilateral cataract but we performed a surgery on his eyes in 2009. Since then his eyes do not possess lenses anymore, but the overall status of the eyes has largely improved. Although restricted in using its visual system Marco is a patient experimental animal for acoustics and haptics.
