[5] According to a NOAA dive report, there was a high density ophiuroids across the sedimented seafloor off the North Carolina coast and can also be seen along the Yucatán Peninsula.

Most species are hermaphrodites, which means that the animal has both male and female sex organs needed to reproduce.

[2] When brittle stars sexually reproduce, their fertilized eggs float in the water and eventually develop into larvae.

These young brittle stars then move on to the settling stage where they sink to the bottom of the ecosystem where they will spend the rest of their life in.

[4] Their gut content varied based on where the brittle stars were placed: those living in shallow habitats mainly consumed plankton and macroalgae whereas those living in deep sea habitats mainly consumed brittle star fragments.

In an experiment, it was observed that the main contents in six different brittle stars included macroalgae, diatoms, bivalves, gastropods, cyanobacteria, marine fungi, and even unidentified eggs (small organisms, brittle star fragments, and sponges).
