That is so cool. The two black jaguar sisters at my zoo used to go swimming when they were young, but will not go in their pool anymore. I love seeing jaguars (or any cat) in the water.
 
Great picture of Salsa. Too bad she isn't allowed in the main exhibit anymore since she started catching the fish like a mad man.

During my visit, the melanistic jaguar repeatedly dived into the pool in an unsuccessful attempt to catch a fish. (There were some large, impressive pacu in the pool.) I was informed by a regular visitor, that this animal occasionally succeeded in catching a pacu and, when she did, she always shared it with her sister, a spotted jaguar. Apparently, the spotted jaguar had never managed to catch one of the fish.

This is the only zoo where I’ve ever seen jaguars swimming underwater and I have never seen such active jaguars in any other zoo. It is a very impressive exhibit, but I did feel sorry for the pacu, though, as they never had a moment’s peace..........
 
Yeah, she got real good at it around March. She figured out to just stay on the log and jump down at the right moment. She went from catching maybe a fish a week to 3-4 a day. She put on 10 lbs in 2 weeks!

The zoo is trying to ship out the Pacu and put in smaller, more agile fish now.
 
wonderfulr photo,

I'm sorry if this sounds a little obvious but does breeding of a melanistic Jaguar and a spotted jaguar work somewhat the same as a regular and white bengal tiger breeding?
 
@dragon(ele)nerd - That is not obvious at all and a very interesting topic. Melanistic leopards work the same as white tigers but not melanistic jaguars. In leopards, melanism is a recessive gene while in jaguars melanism is a dominant gene. What does this mean?

A recessive gene will only show if the animal has a matched pair of the recessive gene, a dominant gene will show if the animal has a mixed pair of the genes (known as heterozygous).

So, a black leopard always has two black genes while a typical yellow leopard could have one of each gene or two yellow genes.

Conversely, a black jaguar could have two black genes or one of each gene while a typical yellow jaguar will always have two yellow genes.

I hope that makes sense.

I thought that was only true in certain populations of Jaguars, or perhaps the melanistic gene is only present in some populations

Very interesting; thanks for the update.
 
@FS Blue - the melanistic gene is only known to occur for sure in south america, and possibly (unconfirmed) in central america.
