This bright-red jellyfish dangles a long, central tentacle surrounded by a multitude of shorter red tendrils.
Crimson Jellyfish CR 4
A crimson jellyfish’s tentacle is a primary natural attack that deals bludgeoning damage.
Environment temperate oceans
Organization solitary, pack (2–4), or bloom (5–12)
The crimson jellyfish is a blood-drinking creature whose red color comes from the blood absorbed throughout its body after it feeds.
A large fish or sea mammal encountering a pack or bloom of these creatures can be drained of blood in a matter of minutes. Fortunately, a crimson jellyfish’s bright color makes it fairly easy to avoid under well-lit conditions.
