Summary

Story summary

A study conducted off Florida finds spiny lobsters, lacking large claws, use chemical signals to gather in groups for predator protection.
The research shows young lobsters are attracted to older, larger ones, drawing them into an ecological trap that increases predation risk.
Typically linked to human activity, the ecological trap results in smaller lobsters becoming prey for groupers, large fish that cannot consume their older counterparts.
