What's the Difference Between a Leucistic Crocodile and an Albino Alligator

Updated on April 9, 2012

Alligators and Crocodiles first appeared during the Eocene epoch, about 55 million years ago. They are reptiles that are scientifically classified as Crocodylia or more commonly known as "crocodilians". It is surprising to know that they are the closest living relatives of birds. Both their ancestors belong to the Archosauria or Archosaurs that flourished in the Triassic geological period 200 million years ago.

People sometimes confuse the term "Crocodile", using it interchangeably for Alligator.

Difference between an Alligator and a Crocodile

■ Alligators have shorter head and broader snout that are U-shaped while crocodiles have a V-shaped snout.

■ Alligators tend to be darker in color, Often their skin are nearly black.

■ Alligators prefer to live in freshwater while Crocodiles are also known to inhabit coastal shores and tidal estuaries. They may even migrate across the sea. This is possible because of a salivary gland they possess which filters out the salt found in salient water from their body. Both species however can survive in sea or freshwater.

■ Alligators are not as aggressive as Crocodiles. More docile and less temperamental, Alligators prefer to furtively slip away to avoid human encounters. Crocodiles almost invariably react aggressively when a person accidentally trespass into their territorial dominion.

Difference between Albinism and Leucism

Albinism (Albino) is a congenital abnormality. It is the total ABSENCE of dark pigmentation called Melanin. However, species that have other pigment cell types are not entirely white but show a pale yellow color.

Leucism is characterize by the REDUCED colorization of ALL types of skin pigment and not just Melanin. Some partial Leucism known as the "pied" or "piebald" effect" produce unpigmented and irregular white patches on the natural skin color of the animal.

Melanin is a pigment or skin colorization that protects against UV (ultra violet) radiation which is responsible for the formation of malignant tumors or cancer of the skin. Melanin changes the color of the transmitted light, absorbing almost all the harmful energy and dispersing it as heat.

■ Another difference that distinguish Albinos from Leucistic animals is EYE COLOR. Because of the absence of Melanin, Albinos have red eyes due to the underlying blood vessels showing through the Iris.Their eyesight are impaired, lacking the visual acuity or keenness to resolve fine details. But most leucistic animals have normal eye coloring and their vision is not affected by their leucism.

How rare are white Crocodiles and Alligators?

Without the dark skin pigmentation for camouflage, it is rare for these animals to survive in the wild. Hatchlings would find it difficult to keep themselves hidden in the dark swamp. They may be able to elude their natural predators for a few days or even weeks. But because of their pale color they are easy prey.

Kept in captivity they have better chances of survival. Sensitive to sunlight, they are house in special enclosure that protect them from the ultra violet rays of the sun.

Out of the more than 1 million adult American Alligator population, it is estimated that there are less than 100 Albinos and only about 12 leucistic gators. Discovered as infants in the swamps of Louisiana and the everglades of Florida, some of the older ones are over ten feet in length and weigh between 500 to 800 pounds. They can be viewed in alligator farms and various zoo and theme parks.

Only 1 in 10,000 crocodiles are hatched leucistic. Albino crocodiles have rarely been sighted in the wilds.

Apart from their unusual lack of dark colorization. Albinos or Leucistic Crocodiles and Alligators share the same physical attributes of their more common variety.

"Popular folklore believe that seeing one of these rare and magnificent creatures would bring good luck and good fortune"

    I just saw 4 of these at Gatorland in Kissimmee, FL. Quite strange looking. I wondered why they were kept inside. Thanks for explaining about their sensitivity to sunlight.

    Cool hub. I like the clear distinction between the two different animals, as well as two different "color morphs."

    leroy64 ~ Thanks again :) I understand that Cajun cooking is very hot (peppery). I sometimes watch Emeril Lagasse's cooking show on cable. Creole cooking appear to be simple yet a very practical way of cooking.

    I can tell you that alligator tail tastes nothing like chicken. I think it one of those things you have to try for yourself. It is not bad.

    Look up Cajuns if you want to know about the swamp cultures in the US. There are other groups that live off of the swamps; but, Cajuns are the best starting point. You will also find this group is know for their skill in the kitchen.

    leroy64 ~ Thank you for the informative comment. it would be interesting to know more about the life style, custom and tradition of the people who make a living in the alligator infested swamps and bayous. In these economic depressive times, we may be able to learn a thing or two about how to live off the land and not depend entirely on the government.

    BTW I'm almost afraid to ask how grilled Alligator tail taste.I'll probably to told it taste like chicken. Although I have eaten "Bayawak" a Philippine monitor lizard and it taste better than chicken :))

    Cookpot, fishing.

    Those words remind me of something. If you happen to drive through alligator country, you will notice a lot of places serving grilled alligator tail, or fried alligator tail. I think that those gators are being raised on farms now for food.

    Alligator hunting, mentioned in some of the comments, is permitted for population control in the swamps. From what little I know about that area of the US, the meat will feed families for most of the year. The skins are at least a half years income. I don't know anyone that hunts alligators for fun.

    Maybe the alligator has the right idea to run away from people.

    Ah yes, my nightmare come true! If they can eat me, I keep a good distance! I didn't know all these differences though so now I have a much more detailed nightmare ;-)))

    Leroy64 ~ I wrote this hub after I didn't know how to answer my grand daughter's question. I am sure that the gators are well provided by the swamps with a smorgasbord of delectable and scrumptious meals. humans with all the junk food we eat won't be missed in their menu.

    But if you unfortunately happen to fall into the cooking pot, isn't it nice to know who's coming to dinner? :))

    I knew there was a difference between alligators and crocodiles; but, I did not know about the shape of the head. I really have not had much use for that knowledge. I try to stay away from creatures that see me as dinner, okay a snack really. We still see a few gators in East Texas, especially since the populations in Louisiana have made a come back.

    Alastar Packer ~ Knowing your interest in fishing. It is admirable that you didn't consider trying this novelty "sport" of bait fishing. We can't fault those people for trying to earn a living. Hard to believe that sadistic impulses made them pursue that method of catching crocodiles. They must have considered other alternatives and found it the most efficient and effective way to hunt.

    MartieCoetser ~ I got stumped by your " crocodiled to the stars" so I google it and came up with "Crocodile Dundee" star Paul Hogan suing the Australian govt. :) then I looked up crocodile quotes... :) and came up with these 2 similar quotes that got me curious about what kind of books Pres. Reagan read....

    An appeaser is one who feeds a crocodile, hoping it will eat him last.~ Winston Churchill

    To sit back hoping that someday, some way, someone will make things right is to go on feeding the crocodile, hoping he will eat you last - but eat you he will. ~ Ronald Reagan

    Thanks Martie for the enigmatic comment :) See you later, alligator. :)))

    Captivating Hub on the albinos Silent. Great pics too. 55 year old Burt almost seems tame. The Kosloski story sure sounds interesting. Theres this show over here called Swamp people that's quite popular. Its about gator hunters and baiting big hooks for money. I know people have to make a living but the alligators suffer & fight hard before being shot. Some feel because they're reptiles its alright but I don't. Anyway thanks for a super hub Silent Reed.

    neeleshkulkarni ~ Unfortunately there are no Alligators in the wilds of India :). As to Crocodiles,I think they are more threatened by us due to human activities that encroach on their natural habitat. The Indian Gharial with an estimated population of less than 200 is an endangered species. Although blamed for human fatalities, the Hindi burial ritual where cremated remains are sent down the river is a more plausible reason why human remains are found inside their stomach. I'll be more cautious with the Indian "Mugger". These Crocodiles have been found in man-made body of waters like reservoir and irrigation canals.

    Thanks, SilentReed, for making it easy for me to distinguish between an alligator and a crocodile. Here's hoping I never have to use that knowledge with the real thing. :)

    always exploring ~ Me too! ;) But when one of my grand daughters ask me "Lolo (grandpa)what is the difference between an Alligator and a Crocodile?" This hub was the result.:) I also added pictures and a video that was more appropriate for kids. Thanks for your comments.

    I must say that this is very interesting. I always thought that alligators and crocks were the same. Thank you.. Well researched hub...
