Alligators
usually follow a series of non-violent behaviors when interacting with
each other.
But they are animals, not machines, just like we are. People, which are
supposed to be "civilized", may react
savagely if provoked in the right
way. The same can be said for any of our domestic animals.
Occasionally,
even alligators will react violently towards each other. It is foolish
to provoke any wild animal,
regardless of size or disposition. The
animals
have a right to live in their habitat, and humans can share it with
them if they take the time to understand the animals.

At
Brazos Bend State Park, the air was cool, but the sun was out.
As
the day progressed alligators showed themselves and moved out of the
water.
Even though the air was relatively cool, exposure to the
sunlight allowed them to collect the infrared and heat themselves.
Circulating blood warmed by the sun from the skin and osteoderms
into
their bodies as the cooler blood was cycled back out would allow, over
time, the alligtors internal temperature to rise higher than the air
temperature. One of our frequent visitors told me
about an alligator with an alligator's carcass in Elm Lake, so I went
to see it. The pictures below show that I found it.
Unlike
from what the popular media might imply, an alligator eating an
alligator carcass is not that uncommon. I usually tell visitors that
although we are seeing an alligator eating an alligator
carcass,
it doesn't necessarily mean that the carcass was killed by that
alligator. It could have been; but most gator fights usually just end
with one submitting and escaping.
Large animal carcasses require
extra effort for an alligator to process. Alligator teeth are not very
good for cutting prey, so they have to spend a lot of time chewing a
carcass to soften it and
weaken connective tissues until the prey
can be shaken apart. Alligators carcasses are especially tough, with
extra bones and strong skin. Some of the close-up images
attached
show that
the teeth have not penetrated the skin of the carcass.
In
some cases, an alligator carcass is swallowed in one piece, without
shaking it apart. I have an example of that from Mother's Day in 2014, on
this page. Comparing the size of this carcass
and the live gator, I think it might be possible for this one to
consume the carcass if it crushed the skull.
From BBSP on 05/29/2022
Water level in Pilant Lake has been receding, due to trail
construction, lack of rain, and the heat. The receding water is
collecting
into various runoff areas and puddles. As I have observed
before, various predators at BBSP exploit these spots for easy prey
capture. However, an alligator will sometimes
try to take possession
of one of the small hunting zones and chase off other birds and
alligators. Sometimes the submission or chase doesn't go as the
aggressive alligator desired,
and a fight could occur. The series
of photos below show such an incident. The gator on the left
was
moving upstream, while the other gator had been moving downstream. Both
had
been foraging in the slow current formed as the water was
leaving from Pilant Lake.The left gator stopped, submerged and turned
away--all signals of submission. I've put these images
and the clips I filmed in to this video file (mp4). (video uploaded 6/20/2022)
While
the gator was submerged, the aggressor gator moved toward it. When the
left
gator surfaced, the aggressor moved towards it.
There
was a short chase until the left gator was caught at the bank. Then the
wrestling started. During the first round, I heard two very loud
"cracks". When I reviewed the video, it appears
that their heads banged together to create those sounds.
That's shown in this
video file (mp4) (video uploaded 6/20/2022)
They
wrestled, paused, and wrestled again. Look at the heightened
body
positions and the gapes of the two angry alligators.
These postures signal high aggression. These were the only
postures
or sounds during this entire event. No snout lifts, tail
arches,
tail swishes, head-slaps, growls, grunts, bellows, nasal spray, or
bubbling. Their backs were higher above the water
than usual, but
this was because they were walking/moving through shallow water. The
aggressive alligator (the "insti-gator" ha ha) only started
this
by moving closer to the other gator.
They
wrestled, paused, and wrestled again. I stayed a safe
distance
away, in case whichever one lost decided to escape by running onto the
trail. Some of these images were direct photos,
and
some are frames from the video. The last two below are from
video
frames. The gator in the foreground has a large gash just behind its
head. This gash would have probably been
worse if not for the
alligator's osteoderms. The osteoderms are the disks of bone arranged
in rows on the alligator's back. I've seen many studies and
reports have been done about them,
and their probable benefit for
crocodilians that have them. Each single osteoderm is a complex
mechanical object with amazing structural strength. Rows of them on the
gators' backs make
a structure that gives protection and allows
flexibility. But along with the armor (which is probably used
mostly in situations like this) the osteoderms also give additional
skeletal
support during movements like high-walks. The osteoderms
have enhanced blood supply internally and externally. This
may help with heat transfer. If submerged for excessive
periods,
the
osteoderms could help regulate lactic acidosis; and also provide
calcium for egg-laying females.
After
the second "round", they moved apart and went downstream with one of
them (I assume the original aggressor, but I lost track while they
wrestled), continuing to get close to or in front
of the other. The
"loser" tried to swim away, but the "aggressor" continued trying to get
in front of it. They finally moved off.
