Shark Bites Whale

Phys.Org mentions an interesting article published in the International Journal of Osteoarchaeology. The article concerns a fragment of a whale rib, dating to the Pliocene, that shows evidence of a shark bite. In this case the rib also displays evidence of having survived the attack. From Phys.Org:

Megalodon and The Great White Shark: Transitional Fossil Found

But, it doesn’t link Great Whites and Megalodon. Longtime readers may remember this three part series on the subject. An interesting new fossil has been discovered that sheds some more light on the subject.

I Thought He Only Studied Lancelets!

That is the name of his blog anyway. Apparently, though, Martin also studies fossils. National Geographic has the story – and this is the clever part – apparently he didn’t even have to go out into the field: But Brazeau suspected that in the right circumstances, some bones could withstand time. So he took a [...]

Reverse Evolution in Sticklebacks?

A number of people have emailed me a link to this story about “reverse evolution” in sticklebacks residing in Lake Washington. The basic story is that as Lake Washington was cleaned of its pollution sticklebacks went from being low plated to being completely plated. Partially, this was a response to heavier predation caused by increased [...]

Rare Frilled Shark Video

MSNBC has video of a female frilled shark. From MSNBC News:

New Species of Hammerhead Shark Discovered

According to BBC News and Science a new species of hammerhead shark has been discovered of the coast of South Carolina. The new species is related to the scalloped hammerhead pictured below.

14 Foot Long Hammerhead Shark Murdered

Long time readers of my blog know I have certain idiosyncratic quirks when it comes to sharks. However, this is just wrong! Apparently, some folks in Florida offed a 14 foot Hammerhead – which may a record for size. Feh, Hammerheads belong in the ocean, not on the end of a hook! Hammerheads (the one [...]

Octopus Killing a Shark

Martin Brazeau at The Lancelet has the video. Apparently, the octopus was moved into a shark tank and developed a regular habit of killing 3-4 foot sharks…

Megalodon and the Great White Sharks: Conclusion

This is the final post in the series… I had originally planned the first post in this series as a companion piece to the Cheetah post for the Friday Ark. One of the points I wanted to address was the issue of great whites preying on juvenile Megalodon. Since cheetahs have extremely high infant mortality [...]

Megalodon and Great White Sharks: Part Two

The Second in the series on Great Whites and Megalodon…. So the question becomes, if Megalodon did not evolve into great whites ( i.e., if they were not a chronospecies) then what happened to cause them to go extinct? One site argues that it was competition with great whites. Specifically, early great whites were outcompeting/preying [...]

Megalodon and Great White Sharks

I am currently working on the second part in my “Evolution of Hominid Limbs” series. In the meantime, I thought I would pull some stuff from the archives and repost it here. This is the first of a three part series on Megalodon and Great White Sharks… Regular readers of this blog may recall that [...]

“We Need a Bigger Boat” or Yikes a Shark

The above is, of course a hammerhead shark. Scientist plan on attaching tags on several of them, according to National Geographic News: In a few weeks, the marine scientist will attach satellite-tracking tags—by hand—to two of the 500-pound (230-kilogram), 12-foot (3.7-meter) predators as they feed off the Bahamian coast. Pratt, a biologist at the Mote [...]

Friday Manta Ray Blogging

Manta rays are interesting creatures. They are, obviously, related to other rays and sharks. Most rays are bottom dwellers. Manta rays, on the other hand, have become adapted to open water.manta 1 They feed by filtering plankton and only the bottom of their mouth has teeth. One of the more distictive features of Manta Rays [...]

Why do I do It?

I was at the grocery store last night and was looking through a rack of discounted items. Stumbled across Shark Attack 3: Megalodon, which is not a sequel to Megalodon. Sucked used kitty litter but I’m a sucker for a shark movie. Maybe there is a twelve step program I can sign up for. Give [...]
