Resembling or relating to disc-shaped jellyfish; having characteristics similar to discomedusae.
From disco- + medusa + -oid (Greek -oeidēs, meaning 'resembling or having the form of'), literally meaning 'resembling a disc-shaped jellyfish.'
The -oid suffix is incredibly useful in biology because it lets scientists describe things that are 'like' something without claiming they are exactly that thing — so 'discomedusoid' means jellyfish-like without being technically a jellyfish.
