Female caudacuta care for their young unaided, in comparison to martima's dual parental behavior. The annual reproductive effort of female caudacuta is higher than that of female maritima. Under reproductive effort theory, as both species' reproductive output is the same, female caudacuta should have a lower probability of survival… CONTINUE READING
