Seahorse are of the genus Hippocampus, from the Ancient Greek, hippos meaning "horse" and kampos meaning "sea monster". Seahorses are not great swimmers so they spend a lot of time with their tail wrapped around stationery objects.
I've been doing a lot of virtual table-top roleplaying games with social distancing. This is my 2nd level fighter from a 2nd edition AD&D game I'm playing in currently.
My son gives me drawing challenges from time to time. He said a T-Rex and Triceratops so I came up with this scene. I'm not sure if these reptiles actually battled it out or not. Strictly drawn for fun on my iPad with Procreate.
