Why baby turtles work together to dig themselves out of a nest | New Scientist
“We knew of this group-digging behaviour, called social facilitation, for a long time, but the reasons for teamwork were unclear. Possible explanations included speeding up nest escape or helping the turtles emerge together to swamp awaiting predators on the beach.
But Mohd Uzair Rusli, a biologist at the University of Malaysia Terengganu in Kuala Terengganu wondered if it could also help individual hatchlings cut down on energy use while trying to leave their nest. This is a major undertaking for the tiny hatchlings, taking several days, with the only source of energy being the yolk that remains when they hatch.”
