No, it’s not a pretty thought.\u00c2\u00a0 It’s not a pretty sight and it’s certainly not a pleasant experience.\u00c2\u00a0 But it is the real world of terrapin conservation and so for the serious naturalist, it’s a necessary learning moment.\u00c2\u00a0 Be thankful that the pictures are two dimensional and that there is no smell-vision key on the video clip.<\/p>\n

Research from September 2000 revealed for the first time that a significant percentage of diamondback terrapins nests in the Wellfleet Bay system were being destroyed\u00c2\u00a0\u00c2\u00a0by fly maggots.\u00c2\u00a0 The infestation appears to begin at pipping when hatchlings poke openings in their eggshells allowing the odor of organic material to escape and to attract flies.\u00c2\u00a0 Since Outer Cape hatchlings remain in their shells and\u00c2\u00a0underground for several days after pipping, maggots have the opportunity to attack an extremely\u00c2\u00a0vulnerable prey as the maggots\u00c2\u00a0work their way through the cracked shell to devour the exposed hatchling.<\/p>\n

In most cases, the maggots begin with the umbilicus and enter the main body of the living hatchling through the yolk sac, hollowing out the baby from within.\u00c2\u00a0 Thus, hatchlings and\u00c2\u00a0whole nests\u00c2\u00a0are destroyed by these insidious predators underground without ever being exposed for counting by researchers like nests\u00c2\u00a0preyed upon\u00c2\u00a0by more obvious predators.<\/p>\n

Observations over the last nine seasons confirm the 2000 discovery and\u00c2\u00a0underscore the\u00c2\u00a0severe constraint this predation places on the number of live hatchlings that emerge on the Outer Cape each year.\u00c2\u00a0 This season (2008) alone has seen more than half of all nests in the\u00c2\u00a0critical habitat of Lieutenant Island infested with maggots.<\/p>\n

Thankfully, the aggressive conservation protocols developed after the 2000 discovery have rescued more and more hatchlings each year from this infestation.\u00c2\u00a0 By checking nests as they begin to pip and harvesting them at the first sign of maggots, our efforts have significantly increased the number of live hatchlings entering the system since the turn of the millennium.\u00c2\u00a0 Even after the infestation has begun, our actions\u00c2\u00a0can save most hatchlings from the most heavily infested nests.\u00c2\u00a0 We harvest the pipped eggs and remove all maggots before re-burying premature hatchlings in clean, moist soil to finalize the incubation process.\u00c2\u00a0 These efforts have rescued thousands of hatchlings that would never have seen the light of day.<\/p>\n

This particular nest on Turtle Point gave\u00c2\u00a0away its location\u00c2\u00a0by a concavity on the surface.\u00c2\u00a0 As hatchlings pip and squirm around inside the egg chamber, sand gets displaced and this underground activity shows itself\u00c2\u00a0as ripples of the surface sand to the most seasoned turtle researcher.\u00c2\u00a0 We were able to rescue 10 baby hatchlings from the devouring horde of maggots in this nest, hand-picking tiny maggots from limb cavities and off yolk sacs, then bathing the hatchlings in clean, fresh water for rehydration before release.\u00c2\u00a0 So, a good day in the Land of Ooze where we saved an order of magnitude better than our goal of one turtle at a time.<\/p>\n","protected":false},"excerpt":{"rendered":"
