Happy Birthday, Wagner, the Oldest Chinstrap Penguin in North America!

December 16, 2015 /

Some people think that age is just a number but at Moody Gardens it is something to celebrate, especially when one of our animals has a milestone birthday!

Wagner is one of 15 chinstrap penguins that we have in our Aquarium Pyramid® and she is the oldest of her species in all of North America! Wagner is turning 32 today which is big deal not only because she is the oldest penguin on this continent but because the general lifespan of her species is only in the mid-twenties.

While living in our South Atlantic Exhibit Wagner generally enjoys spending her time swimming but on her birthday we planned a little something extra. Wagner was presented with a special ice sculpture modeled after the Aquarium Pyramid® that she lives in and she seems to know that it was all about her today. She is typically more aloof. Today, she was frolicking in the water and interacting more and seemed to enjoy her birthday party. The children outside the exhibit also enjoyed her party, as they sang Happy Birthday to Wagner. Please join us in wishing Wagner a very happy 32nd birthday and send her a congratulatory message on being the oldest chinstrap penguin in North America!

Also be sure to see Wagner in person before the penguin exhibit temporarily closes from January 11-March 11 as part of the aquarium renovations. (Don’t worry though; the rest of the aquarium exhibits will still be open during this time.) Before the penguins go on hiatus there is still time to come visit our South Atlantic friends! You can get up close to our penguins as part of the Moody Gardens Public Penguin Encounter. The encounter lasts for 45-minutes and allows you to get up close to one of our penguins like Wagner. During your experience you are led by a Moody Gardens biologist from the front of the exhibit to behind the scenes of the penguin food preparation kitchen and then to the back of the chilly penguin exhibit. This is all while discussing penguin biology, conservation, training, enrichment and care with your Moody Gardens biologist.

Come experience the cool climate and sounds of the exhibit and witness a penguin create a work of art with a penguin painting as part of an enrichment activity for the animal! More information on the Moody Gardens Public Penguin Encounter can be found here. You can even purchase a penguin painting in our Aquarium Gift Shop. Proceeds from the painting go toward animal conservation projects. It’s a very unique gift for the animal lover in your life!

Shark U Week: Know Your Sharks

August 9, 2013 /

How well do you know your sharks? Odds are most people only know the sharks that have been portrayed as vicious killers in Hollywood thrillers, such as the mighty great white shark in the 1975 blockbuster hit “JAWS.” But the truth is there are over 400 different types of sharks in our oceans and aquariums all over the world and, despite all the horror stories, sharks do not eat people.

Sharks come in all sizes from the massive whale shark, reaching lengths of 30 feet, to the dwarf lanternfish that’s less than 10 inches. Being able to tell the hammerhead from the nurse shark is quite easy, but others can be difficult. Can you spot the difference between a leopard shark and tiger shark?

How can you tell one from the other?

IT’S ALL IN THE BITE:

IMG_5603Sharks’ teeth are adapted for what they eat. Sharks like the great white and tiger shark have triangular teeth with jagged edges. This keeps hold of larger fish and animals, tear chunks of meat or slice through a turtle’s shell. A sand tiger’s teeth, on the other hand, are long and narrow which make them look frightening, but in fact these types of sharks are not very aggressive. The shape of their teeth is ideal for grabbing a hold of prey. However, the whale shark has very small teeth and it’s not used for biting because they simply filter their food.

SHARK MARKS:

IMG_5627Coloration and patterns play an important role in identifying a shark. Their special marks allow them to camouflage perfectly into their environment. Mako sharks, for example, inhabit tropical and offshore water and are normally a bluish color. On the other hand, the nurse shark has a tan pigmentation ideal for hiding on the ocean’s floor. Tiger sharks can be identified by their stripes and leopard sharks for their spots.

LOCATION, LOCATION, LOCATION!

Know the sharks that lurk in the water. Sharks can be found all over the world from the warm waters of the Caribbean to the freezing temperatures of the arctic. The Gulf of Mexico alone houses more than 50 different species of sharks including, on the rare occasions, the great white shark. The bull shark and blacktip shark are quite common off the shores of Galveston while the Caribbean reef shark is obviously in the Caribbean.

 

Sharks: A more diverse species than most realize

August 15, 2012 /

By Greg Whittaker

Working in the zoo and aquarium industry offers a lot of perks. That’s because we get to work with some of the coolest animals in the world.

As I was walking through the exhibits looking at what our guests see, I started counting the species of sharks and rays we house at Moody Gardens® and the diversity they represent in habitat, diet, behavior and natural history. From the secretive swell sharks and wobbegongs to the large active brown sharks and sand tigers, we have 22 species from Galveston’s local waters to Australian reefs from the other side of the world. We have three species of stingrays that are found in the Amazon River basin and are so completely adapted to living in freshwater that they can’t exist in the brackish delta.

One of the questions we answer while walking through the public galleries is, “Where are the sharks?” Over time we’ve come to realize that most guests are referring to the Caribbean exhibit and the large, easily recognizable species.

You might be surprised to hear that four out of these five are relatively common species in the waters just off Galveston. If they truly were the bloodthirsty human predators they’re portrayed to be, we surely would be losing more tourists and fishermen to the sharky menace.Looking at the tremendous diversity of sharks, rays, skates, guitarfish, sawsharks and sawfish all collectively grouped together as cartilaginous fishes, there are over 1,200 different species. The sharks that gain all of the attention are the ones that grab the headlines in “attacks” on humans, and the five that are generally agreed upon as the top “maneaters” are – great hammerhead, lemon, bull, tiger and white sharks.

In reality, the vast majority of the 100 incidents that are reported worldwide annually are cases of mistaken identity with small, non-dangerous species. Contrast those statistics with the estimated 350 to 500 million sharks that are removed from the world’s oceans every year. Many of those are reproductively mature adults of species that are in perilous population declines and in some cases, they have their fins cut off and are dumped back into the water to die.

Even if you don’t particularly like sharks, you have to see how wasteful shark finning is.

Back to the amazing diversity – whale sharks are the largest fish with a maximum length of 45 feet and weighing as much as 36 tons. Along with basking sharks and megamouth sharks as the most menacing-sized sharks, they all filter feed on plankton and small fish. On the opposite end of the spectrum, the tiny cigar shark reaches a maximum size of only about eight inches long.

The biggest ray species is the manta which can have wing tips that measure almost 24 feet wide and weigh almost 3,000 pounds. Electric rays generate powerful electric currents that protect them from predators and assist in navigating dark murky water and capturing prey. Between sharks and rays is an assortment of species that have aspects of their appearance that match both – a  generally flattened body with elongated tails. These include angel sharks, guitarfish, sawsharks and sawfish.

Sharks can fill ecological niches from scavengers to apex predators and have reproductive strategies that include eggs deposited within the reef to complex internal egg incubation, internal hatching and internal cannibalism of siblings.

From this rambling account, you hopefully have gained enough perspective to realize that “sharks” cannot be painted with a simple broad brush stroke. They generally all came from ancient ancestors hundreds of millions of years ago. They fill every available niche and are remarkably adaptable to environmental changes and pressures placed on them.

For every species we can provide care for in the captive aquarium, there are dozens of other species that we simply don’t know enough about.  It’s a safe wager that there are untold numbers of species out there that we haven’t even discovered yet.
