Pseudobiceros fulgor,[1] also known the lightning worm, is a species of marine flatworm from the family Pseudocerotidae and belongs to the class Turbellaria.

[5] They inhabit shallow coral reefs, internal areas and seagrass beds that can be shared with crustaceans and mollusks.

A key feature that helps Pseudobiceros fulgor with survivability in their environment is the ability to regenerate its body when injured.

[editorializing][citation needed] Pseudobiceros fulgor are hermaphroditic, which means that the male and female both have their respected reproductive organ.

[8] The fertilized eggs develop into juvenile flatworms and mature as smaller version of the adult due to no larval stage.

[9] In order to move, Pseudobiceros fulgor use cilia which are hair like structures that cover the entirety of their body.

The background color of orange brown and the longitudinal broken streaks of white are what deems them the lightning worm.
