- Coral Reefs: Many Echinosquilla species prefer the complex structure and rich biodiversity of coral reefs, where they find shelter and abundant prey.
- Seagrass Beds: Echinosquilla can also be found in seagrass beds, which provide a dense habitat with ample food sources.
- Rocky Shores: Some species of Echinosquilla prefer rocky shores, where they can find crevices and hiding places.
