Tim’s kids hunted ghost crabs with flashlights on this beach for fifteen years. Here is what to know about the crabs on 30A and why nighttime crab hunting is one of the genuinely memorable things you can do here.
Ghost crabs — the main event
Ghost crabs are the dominant crab species on 30A’s beach. They come out after dark, moving fast across the dry sand in unpredictable patterns. They are pale, nearly translucent, and almost invisible until a flashlight catches them — hence the name. They are completely harmless to people. They will not approach you and they will not pinch unless you pick one up, which you should not do. They dig small burrows in the dry sand above the tide line — you can see the burrow openings during the day, small holes about an inch across. At night the owners emerge.
How to hunt ghost crabs
After dinner, after dark, walk to the dry sand above the high tide line with a flashlight. Scan low across the sand — ghost crabs move fast and hug the ground. When you spot one, move the light slowly toward it. They freeze briefly before bolting. Children respond to this activity the same way every trip: initial excitement, then total obsession that lasts the whole week. No equipment needed beyond a flashlight. No skill required. Universally successful as a family activity.
Blue crabs
Blue crabs appear occasionally in the shallow Gulf water and in Eastern Lake, particularly during outfall events when the lake and Gulf connect. They are larger than ghost crabs, visibly blue-clawed, and distinctly not interested in people — but they will use those claws if handled. Watch them in the water, do not pick them up. Children who wade in Eastern Lake occasionally encounter blue crabs near the marshy edges of the lake. Interesting to see, harmless if left alone.
An important note for turtle nesting season
Sea turtle nesting runs May through October on 30A. During this period, keep flashlight beams pointed toward the sand, not toward the water. Hatchlings orient toward the brightest light — historically the moon reflecting on the Gulf. Artificial light from the beach confuses them and sends them inland rather than toward the water. Keep your light pointed down when crab hunting during nesting season. The ghost crabs are just as visible, and the turtles benefit.
