Leptasterias can also be used as an indicator species as they are not very able to move far from their habitat and are susceptible to local selection pressures like algal blooms and disease outbreaks.

[5] To do this, it is important to identify the certain species of Leptasterias in order to accurately observe changing distributions, abundances, and population health.

The cryptic complexes also play a part in determining data for monitoring ecological effects of disastrous events and other environmental stressors.

[6][7] Young are found in the rocky substrates in the shallow water while adults usually venture out to greater depths.

[11] During this time, it is important for the starfish to be beneath rocks due to the possibility of the tide to disperse the sperm elsewhere.

[6][12] Leptasterias do not partake in actual sexual intercourse, but it is essential for the starfish to be in close proximity of each other to better ensure reproductive success.

The male spawning period lasts for about 2 hours in order to ensure there are viable sperm present for the female eggs.
