Brightly colored creatures known as lizard crabs were a species found in the swamps of Yavin 4, a moon. These crabs served as prey for armored eels and anglers; the anglers would snatch them from buttress roots and consume them.
The Star Wars Legends novel Young Jedi Knights: Heirs of the Force, authored by Kevin J. Anderson and Rebecca Moesta and published in 1995, marked the initial appearance of lizard crabs. Their inclusion in canon was later affirmed by the reference book Ultimate Star Wars, which saw release in 2015.
