found a dead shark

[Gabriel90512]

I was diving with jchaplain and another guy (cant remember his name) last weekend and we found a dead shark .. about 3 feet long .... not a dog shark ...
his friend with the dig cam got a good pic of it ...
gray on top .. white on the under side and the nose was a point. this was in boston harbor .. we were diving some rocks
with a very small WWII Army bunker on the top of it.

Might be a small porbeagle shark(Lamna nasus)... they are pretty common and basically fit that description, but without more info that is a wild guess. Gray on top, white on the bottom with a pointy nose could describe a lot of sharks.

Take a look at these links for comparison:

looks kind of like the first link .. but very small...

All the sites you posted neglected another common name for this shark. I've known several fishermen who refer to them as "fakos", because they look similar to makos aside from the white spot on the posterior dorsal fin and the extra channel at the base of the caudal fin.

Of course, it could have been a mako too... if it was dead, it may have been sick and behaving unusually. I wouldn't expect to see a healthy one inshore.

here is a crapy pic of the dead shark

I can't really tell much from that pic, except that you aren't doing yourself any favors by using the flash.

It looks like it was a female (but it may be that I just can't make out claspers in the photo), but it's hard to tell much else between the backscatter and the ventral viewpoint. Did you move or examine the carcass at all? What did the teeth look like?

My first thought was Mako, but hard to tell from the pic, it looks a little fatter than the Mako.

Could just be bloating?

we were down 60 feet and the vis was crap
i did not take the pick .. but the flash was a little much.

the teath were small with a long thin point ....

in the pick the shark is in its side ... the head is to the left
you can see into its mouth ..
