Taken at Sunset Dam on Saturday:

These Impalas went right around the dam to go and drink next to the Crocodiles that were lying on the edge….quite strange, don’t you think?
Might it be that they feel safer when they can see the crocs?
Some of them however got very close to the crocodiles. :shock:
(photos were taken by my husband, I forgot my camera at home :cry: )

I am only aware of the nile crocodile and the African slender-snouted crocodile that is found in Africa. Which is the other?

Crocs and Hippos

Unread post by ice » Sat Nov 24, 2007 11:22 pm

a few months ago I came across a pool where both hippos and crocs were living in...in one corner there was dead hippo, belly up...judging from the stench I would think it had been dead for a few days when we got there...yet there were no appearant signs that the crocs had started to feed on it...so I wonder:

do they generally NOT eat hippo meat? or does it take for time for the hippo to decompose before the crocs are able to tear it open? what about other animals (lions, hyenas): shouldn't they try to get a share of it? it was quite close to the shore, not very deep in the water...

Crocodile have no problem eating hippo meat! Nor do they have any problem to tear open a hippo.

They do it through the so called "death roll". They grab hold of the prey, and turn their whole body, thus tearing off pieces.

As to your observation ... there could be many explanations.

Maybe they had started eating, but it weren't obvious from your vantage point.

Maybe they had eaten previously, and had no appetite?

Maybe some other hippos kept them from the dead one?

And yes, other predators and scavengers will also eat dead hippo. They will even wade in to the water and try to pull the hippo ashore.

In this little video you see a very old Crocodile on the Road near Lower Sabie at the Sunset Dam. :shock:

Okay... So... I think that only Nile Crocodile is found at Kruger Park, but I saw this little lad last month... Is he just a young Nile Croc?

Ah, I see.. Thanks.
That's what I thought...

Is it possible for Kruger crocs to become somewhat deformed? I really must locate the other picture I took, it must have been a couple years back now, but he had the most unusual risen section on the top of his head. Is this normal? Looked like nothing I'd ever seen before, and I've seen my fair share of crocs. :|

A somewhat misleading statement.
Crocodiles are like most reptiles poikilothermic.
In other words they rely on external factors, like the sun, to heat their bodies to the desired temperature.
Once they reach their desired temperature they thermo-regulate, moving into and out of water or into shade to maintain the desired temperature.
That is where it stops.
They do not tap energy from the sun that will enable them to survive with the minimum intake of food.
They can and do consume huge meals and in summertime eat regularly.
They, like all reptiles eat less frequent in the colder months of our winters and may in this time go without food for lengthy periods.
If they did not have ample food intake during the summer they may die during winter, because they do not have the reserves to see them through winter.
This may explain why one will sometimes see photo's of impala etc. in close proximity of crocodiles.
It may also explain why they have not eaten on the hippopotamus.
In cold weather the cannot digest food.

Thats a perfectly normal crocodile. They develop these "knobs" and it gets more pronounced with age. The black "hole" is just a shadow. (See the shadows of the scales on his neck.)

Crocodiles have both a septate lung and a diaphragm—an organ not found in snakes, lizards, or birds.
But the crocodile diaphragm is also somewhat different from that in mammals.
It is not muscular but is attached to the liver and movement of this liver/diaphragm acts like a piston to inflate the lungs, with muscles attaching to the pelvis.
(The mammalian [including human] diaphragm pulls the liver in the same way a crocodilian one does, creating a visceral piston, but the way this is accomplished differs in crocodiles and mammals..."
I Googled crocodile diaphragm and amongst others this came up. The scaly skin hides a lot of secrets!
