Where Sea Monsters Roam (2020)

While on a field expedition investigating the mysterious superheated mineral waters rising from Earth's mantle into Maug Island's cove, marine biologist Dr. Maxime Rostand performs an emergency C-section on a dead shark caught in a trawl net, only to discover a new species - Carcharocles daemonium - a 60-foot Mako, prehistoric cousin of the modern-day Black Demon shark, reported to inhabit the deep waters in the Sea of Cortez. Faced with the risk of introducing an apex predator into our oceans, Dr. Rostand and his companions soon discover there are even more terrifying sea monsters inhabiting the ancient aquifer.
