I changed my idea from a simple shark like creature made of kelp to a larger slightly more complex creature inspired by prehistoric aquatic reptiles and fish such as mosasaurs and dunkleosteus both large predators in there eras. The latter being a large fish who’s head was covered in thick bone plates which I may add onto my sketch to add a more defensive side rather than the almost entirely sleek look. I also looked at different whale skeletons like the orca and sperm whale, I also looked at the skeleton of Livyatan a huge whale who was named after the author of Moby-Dick.
