Hello first mind I would like to thank @jacintasevilla , for this art competition but also for the conservation awareness of marine species especially dolphins and whales.
I present to you the "Pink river dolphin O Inia geoffrensis" which is the largest freshwater cetacean in the world. It reaches lengths of up to 2.80 m and weighs 180 kg. Its color is variable, generally when it is born it is dark gray and as it grows it can stay the same or present a great variation from gray to pink

I hope you like it and a thousand blessings to all of you
