The Book of Shells

The Book of Shells

July 14, 2010 - The Book of Shells offers a visually stunning and scientifically engaging guide to six hundred of the most intriguing mollusk shells, each chosen to convey the range of shapes and sizes that occur across a range of species. Each shell is reproduced here at its actual size, in full color, and is accompanied by an explanation of the shell’s range, distribution, abundance, habitat, and operculum—the piece that protects the mollusk when it’s in the shell. Brief scientific and historical accounts of each shell and related species include fun-filled facts and anecdotes that broaden its portrait.

The Matchless Cone, for instance, or Conus cedonulli, was one of the rarest shells collected during the eighteenth century. So much so, in fact, that a specimen in 1796 was sold for more than six times as much as a painting by Vermeer at the same auction. But since the advent of scuba diving, this shell has become far more accessible to collectors—though not without certain risks. Some species of Conus produce venom that has caused more than thirty known human deaths.

The Zebra Nerite, the Heart Cockle, the Indian Babylon, the Junonia, the Atlantic Thorny Oyster—shells from habitats spanning the poles and the tropics, from the highest mountains to the ocean’s deepest recesses, are all on display in this definitive work.

15' Great White Seen South of Nauset Beach

July 13, 2010 - On Sunday at around 4pm a 15' great white shark was spotted chasing seals in shallow water 2 miles south of Nauset Beach. This was the second great white seen in the region this season. At the end of June a 7' white shark was caught, tagged and released north of Provincetown. Atlantic coast beaches in Chatham and Orleans remain open. Authorities advise vigilance and avoiding concentrations of seals.

Boston Harbor Creature Thrives in BP Oil

Boston Harbor Creature Thrives in BP Oil

July 8, 2010 - A wide range of sea life is being badly hurt by the recently oil infused waters of the Gulf of Mexico.  But some creatures love it. In particular, a worm known as Capitella capitata seems to thrive survive in a polluted environment. The worm's natural predators—shrimp, fish, and crabs—start to die off after a spill, leaving room for what's called ecological succession: The population of one species grows to fill a gap left by damage to another.  A large number of worms suggests poor water quality.For example, Capitella has been tracked in water near sewage outfalls, such as parts of Boston Harbor.  Here's more from Alan Siegel at Slate.

Macho Mouth Whale Terrorized Miocene Seas .

Macho Mouth Whale Terrorized Miocene Seas .

July 2, 2010 - The fossil remains of a giant toothed precursor to the modern day sperm whale have been found in Peru's Pisco basin.  It's called Leviathan melvillei after the biblical name for a whale and the author of Moby Dick. The most salient feature of the prehistoric beast were its giant choppers, which measured up to 14" long. The 45' whale lived alongside massive sharks at the top of the food chain some 12-13 million years ago. Leviathan melvillei gripped large prey with interlocking teeth, inflicting deep wounds and tearing large pieces from the bodies of its victims. Palaeontologists have long suspected that some such air-breathing monster once roamed ancient seas, but until now only a few gigantic teeth had turned up in the fossil record. Here's more from Australia's ABCNews.

White Shark Tagged North of P-Town



June 28, 2010 - On Saturday a white shark was tagged and released in Stellwagen bank north of Provincetown.  Here's the story from the SWEET DREAM III:

Today the crew of the SWEET DREAM III tagged and released a 7' Great White Shark on Stellwagen bank. We were tuna fishing with live mackerel when the shark came along to check out our baits. It was in no hurry to eat but after 10 minutes of terrorizing the pair of mackerel it finally could not resist and ate one and Jon Land fought it standup style on a PENN 70. Once we had it boat side we were pretty sure what we had and decided to put one of our tuna tags in it so it could be tracked in the future. We got some great video is now posted here. The shark was really a beautiful creature and we are fortunate to have seen one up close and personal. The identity of the shark was confirmed by Dr. Greg Skomal.

A meeting is scheduled today at 11:15 am at New England Aquarium in Boston to discuss the sighting. Attendees will include:

  • EEA Secretary Ian Bowles
  • New England Aquarium Staff
  • DMF Director Paul Diodati
  • DMF Biologist Greg Skomal
DMF biologists completed the first successful tagging of white sharks in the Atlantic Ocean last September using electronic satellite technology. Four of the five tags have successfully surfaced revealing data about the shark's locations and migratory paths.
