Physical
Description |
- Is the largest cat in the Americas
- Jaguars are very similar in appearance to leopards but are larger, more muscular and have larger heads
- Both animals are short, stocky, muscular cats
- Both have a yellow / golden undercoat with black rosettes but the jaguars’ are larger and generally have a spot in the middle of the rosette (leopards generally do not)
- Rosettes change in size, shape and thickness from cat to cat
- Belly and neck of the cat are white
- The backs of the ears are black with a faint spot in the centre
- Some carry a recessive gene causing the production of too much melanin resulting in the cat looking black – this is referred to as a panther (a melanistic jaguar or leopard). If the jaguar sits in the light, you will still be able to see it’s rosettes as the undercoat is a dark brown due to the melanin, and the rosettes are still black
- Their canine teeth are more robust and their bite is the most powerful of the big cats

Diet & Hunting |
- An opportunistic predator that will eat pretty much any animal that presents it the opportunity
- Will eat things as small as reptiles, turtle eggs, fish, wild pigs (peccaries), right up to deer or domestic cattle weighing over 4 times the cats weight
- As they love the water, they do hunt turtles and crocodiles
- Ambush predator
- Kill their prey with a bite through the skull with their massive canine teeth – this is a technique unique to jaguars. With some prey they also use the common neck or throat bite
- Will drag their larger prey into a protected area before eating
- May spend 2 – 3 days with a carcass and will not cover it if they leave
- Captive jaguars eat approximately 1.4 kgs of meat per day

Social System & Territories |
- Solitary animal only coming together to mate, or a female with cubs
- Like most cats, males typically have a large territory that overlaps with a number of female territories
- Males will retain exclusive breeding rights to females in his territory as long as he can defend
- Depending on the amount of prey, territories vary from 90 km2 to 200 km2
- Communicate with each other using cheek rubbing on trees, faeces, urine and spray marking (urine with scent gland secretion) sprayed on rocks, trees, bushes etc. to mark territories
- Flehmen – allows olfactory & chemical clues to pass over naso-vomeral organ positioned in the roof of the mouth
- Visual marks are also left with scrape marks (scratching hind feet in the dirt) and scratch marks left on logs and trees
- Are best known for their guttural roar which has been likened to thunder
