Read in-depth details about Caught on Camera: Inside the Relentless Feeding Habits of Blue and Green Crabs.

Tracking what decapods eat provides essential indicators of marine food web resilience.

Fisheries managers now rely on real-time stomach isotope tracking and underwater monitoring to protect soft-shell clam beds and critical eelgrass nurseries from overconsumption. Understanding the balance between active hunting, detritus grazing, and cannibalism remains the cornerstone of modern coastal conservation.
