Hallowings and things…

In honor of Halloween, the animal encounters at the National Aquarium have been a bit spooky this week!  We have been introducing some of our slithery, slimy, creepy, crawly animals from the rainforest, and teaching visitors that these animals aren’t as scary as we may think..

One of the encounters includes tarantulas. Scared yet? Don’t be. Though these venomous crawlers are generally thought of as a danger to humans, they do not pose the slightest threat. Tarantulas have venom with the potency comparable to a bee, so their venom is generally not toxic to humans. 

What’s the slimiest creature you can think of? A snake? This preconceived notion about snakes is false! These reptiles are not slimy at all; in fact, they are covered with scales. Snakes have small scales on the top of their body and large scales on the bottom. The large scales, called scutes, help them move their legless bodies. The coloration of their scales helps snakes camouflage themselves in various surroundings. They can blend in with leaves, shadows and even rocks! 

What has six legs and teeth in their stomachs? Give up? Cockroaches! These fascinating creatures have existed for about 300 million years and were found even before dinosaurs! Even though we see them as pests, cockroaches actually do a lot for the earth. In the rainforest at the Aquarium they help spread nutrients from trees to the soil.

 

 

 

 

 

 

You can find out more about these animals and others at the Hallowings and Things encounters everyday at 10:30 a.m. through November 6th! 

We are also running a special special halloween contest on facebook through Monday. Click here to enter the Hallo-Marine AquaFaces contest! Build your creepiest AquaFace for a chance to win tickets to the National Aquarium’s Baltimore venue.

Happy Halloween!

Ayers the bat recovers from surgery

Thanks to the help of the Aquarium’s veterinary staff and Dr. Anne Minihan, a surgical specialist from Chesapeake Veterinary Surgery Specialty, Ayers, a grey-headed flying fox, or fruit bat, is now recovering from a broken wing.

Ayers is a 7 year old flying fox that lives in the Aquarium’s Australia exhibit. In mid-August, he suffered a distal humerus fracture. Ayers’ skin was torn open allowing his humerus bone to protrude through. This type of injury is difficult to stabilize and put Ayers at risk for developing an infection. In bats, the humerus bone is surrounded by tissue that creates the flying surface of the wing, so a cast was not an option.

The best chance Ayers had to regain full function of his wing was to bring in Anne Minihan to complete a surgical fixation. Surgery was performed the day after the fracture occured, and it went very well but the recovery process is a slow one. There are several pins in place to stabilize the bone as it heals.  Ayers has been using his wing and thumb regularly now and is scheduled for another check by the orthopedic surgeon in the next few weeks. Even though Ayers is not fully recovered, the aviculturists in the Australia exhibits have said  he is acting like his batty self again!

Bats are commonly associated with Halloween and tend to frighten many people! Contrary to common believe, bats have no intention of bringing harm to humans. In fact, they do more for us than you may think. Insect-eating bats protect our crops, keeping costs down at the market. Fruit-eating bats help with pollination and seed dispersal, thus providing us with many commercial products and medicines.  Survival efforts are imperative worldwide because bats are such a vital part of our ecosystem. This halloween, celebrate bats!

American alligators, feeding time

The American alligators on display at the National Aquarium’s DC venue are very popular with visitors, especially during feeding time!

Through a partnership with the Savoie alligator farm in Lousianna, the National Aquarium receives several alligators to raise for a few years, until they out grow the alligator habitat at the Aquarium. The alligators are then taken back to Louisiana and released into the wild to help regulate the populations that were once deminishing.  In the video below, Ryan Dumas, a herpetologist, introduces the American alligator, and explains the process of feeding the alligators within in the exhibit.

Rescued sea turtle awaits release

After spending over a year in rehabilitation at the National Aquarium, the loggerhead sea turtle rescued by the Aquarium’s Marine Animal Resque Program (MARP) last July is now ready to be returned to the ocean! The MARP team will release the turtle from Assateague State Park on Saturday, September 19th in conjunction with Maryland Coastal Bays program’s Coast Day event.

MARP rescued the turtle after it was found in dire condition by the United States Coast Guard off the coast of Ocean City, Maryland. The underweight turtle had living organisms and epibionts embedded on its shell, so it could not dive properly. Fortunately, with the help of Johns Hopkins Hospital and Outpatient Center, the Aquarium’s vet team was able to bring the the turtle to full recovery.

Here is a recent video of the turtle swimming about in the rehabilitation pool:

This was one of the longest rehabilitation periods for a marine animal rescued by MARP.  Within months, the turtle’s shell surface healed and it was able to regain diving ability and a normal diet.  Achieving these tasks enabled the struggling, 57 pound turtle to gain weight. Since then, it has enjoyed a diet of capelin, squid, and blue crabs and has been maintaining an ideal weight of 90 pounds. The turtle’s rehabilitation period was extended, however, due to infections that had grown deep into the shell as a result of the embedded organisms.

Howie the sloth turns 1!

This week the Aquarium is celebrating the birthday of our very first sloth baby!

Baby Howie, a Linne’s Two-toed Sloth was born on exhibit in the Upland Tropical Rainforest on September 2, 2008. His parents, Rose and Syd as well as another adult female sloth, Ivy, have remained on exhibit with Howie as he has grown over the last year.

 At birth Linne’s Sloths weigh only 1 pound and are born with their eyes opened, claws intact and fully furred. They hold tight to their mothers and rely on them for warmth, security and milk for approximately one year. By this age, the baby sloth is normally a whopping 5 pounds and ready to venture out on its own. Howie and Rose parted ways right on schedule on August 31, just 2 days shy of his first birthday. Here is a picture of Howie and Rose, just days before they parted ways:

Howie can often be seen napping or enjoying his diet of zucchini, squash and grapes. Because the sloths live nestled in the rainforest trees, they are hard to spot! During your next visit to the Aquarium’s rainforest be sure ask an exhibit guide to help you find Howie and the other sloths.

In lieu of presents, you can TXT the word ACT to 20222 to give Howie a gift! Your $5 donation will support the care and feeding of Howie and his 16,000 friends at the Aquarium.
