Animal Rescue Update: Turtle Nest Excavated at Assateague

national aquarium Animal Rescue Update

National Aquarium Animal Rescue staff recently joined the National Park Service (NPS) and the Maryland Department of Natural Resources (MD DNR) to excavate a loggerhead sea turtle nest at Assateague Island National Seashore.

The nest, laid on July 1, 2013, has been monitored by NPS staff for the past three months. While the typical incubation period for sea turtle nests south of North Carolina is approximately 60 to 70 days, northern sea turtle nests, such as those laid in Virginia, Maryland and even Delaware, are known to incubate for a longer period of time due to typically cooler temperatures.

After 110 days, this nest had not hatched and an excavation was planned for Friday, October 18. Excavation of nests is a standard practice to determine hatchling success and stage of development. During the excavation, the team collected detailed data such as depth and dimensions, temperature, as well as number of eggs in the nest.

It was determined during the excavation that the turtles had not yet hatched, and there was still a possibility that the nest was viable. The eggs were carefully transferred to a transport container and brought back to our Animal Care Center for incubation.

Our team is working closely with the Aquarium’s senior herpetologists to carefully incubate and monitor the nest. We are slowly warming the nest in a temperature controlled, humid environment and should have the nest warmed to an ideal temperature within a week. Sea turtles are reptiles and are therefore sensitive to temperature changes, so the process must be done very slowly. While we have seen signs of a potentially viable nest, we are cautiously optimistic about the total number of live hatchlings that might emerge.

As you may recall, we experienced the first confirmed successful sea turtle nest in Maryland last year. Our team was ecstatic to hear that the lone surviving hatchling from that nest was released off the coast of North Carolina back in April!

This nest represents a larger joint initiative with our partners at NPS and MD DNR to plan for and respond to these events.

Stay tuned for more updates on the nest!

Animal Rescue Update: Loggerhead Patients Ready for Release!

national aquarium Animal Rescue Update

It is a bittersweet, yet exciting time of year for the remaining patients at our rehabilitation center.  Our remaining two loggerheads have passed their exit exams with flying colors and will be commuting to the warmer waters of southern Virginia for their release on the 21st of October!

As you may remember, Rooney, one of the first cold-stunned turtles of the 2013 year, has actually been with us since December 23, 2012.

Husbandry staff and veterinarians had started treating a chronic abscess that Rooney developed with honey, but quickly realized that the abscess needed to be removed all together.  On June 27th and September 18th, a soft tissue surgeon came in to assist our veterinarians with the abscess removal.

As you can imagine, being sedated for exams and surgeries is a very different experience from what these animals encounter in the wild, so we are very anxious to get Rooney back into his natural habitat where he can swim freely and forage for his favorite foods like blue crabs and squid.  While in rehabilitation with the National Aquarium, Rooney gained 19.3 pounds, and is currently consuming a diet of blue crabs, squid, shrimp and lean fish!

Our second loggerhead, Portsmouth, was transferred to our facility in August.

On August 28th, veterinary staff was assisted by a specialist for an endoscopy procedure to remove the last of two hooks he had ingested.  The hook removal was a complete success, and staff starting including more foods into Portsmouth diet, like blue crabs. While in rehabilitation, Portsmouth gained 6.6 pounds!

Husbandry staff are working with the Virginia Aquarium now to get plans for the release into place. Stay tuned for more news and photos from their release!
