Shoal Serpent

D&D 2024 monster: Shoal Serpent. Source: Plane Shift: Zendikar. challenge rating 2, creature type Beast, Large size, speed 20 ft., swim 40 ft. The oceans, bays, and swamps of Zendikar are home to a variety of aquatic creatures that are at least as deadly as those on land, including monstrosities that can face the largest Eldrazi on almost equal footing. Given the dangers of Zendikar, even mundane animals such as octopuses, frogs, turtles, crabs, and crocodiles can grow to tremendous size (using the appropriate statistics from appendix A of the Monster Manual). The crabs of Ondu, the crocodiles of Guul Draz, the tortoises of Tazeem, and the octopuses of the deep sea (of which Lorthos the Tidemaker is but one giant specimen) are examples of these aquatic monstrosities. Enormous shoal serpents-sometimes compared to "a reef that runs aground on ships"-are a persistent danger to vessels along the Onduan coast. The plesiosaurus in the Monster Manual can represent these serpents. Beast Large 20 ft., swim 40 ft.
