The mated pairs of chain dogfish are currently on exhibit and continually produce egg cases at a rate of about one every two weeks. Females will wrap the tendrils of the egg cases around structure to anchor them during incubation, but it also helps her literally pull the case out of her body. In the exhibit, she expertly wraps the cases around a display box in which we display developing embryos.
The egg cases are anchored by strands that the female wraps around a solid object
We will keep the juveniles in a holding system until they are large enough to display with the adults.
