Researchers Complete Mollusk Evolutionary Tree

Mollusks have been around for so long (at least 500 million years), are so prevalent on land and in water (from backyard gardens to the deep ocean), and are so valuable to people (clam chowder, oysters on the half shell) that one might assume scientists had learned everything about them. “Here´s this big, diverse group of animals, and we don´t know how they were related to each other,” said Casey Dunn, an evolutionary biologist at Brown University who specializes in...

Deep genomic analysis of Molluscsa shows there is more than 1 way to make a brain Seemingly simple animals such as the snail and squid have ransacked the genetic toolkit over the last half billion years to find different ways to build complex brains, nervous systems and shells, according to an international team of researchers, including a neuroscientist with the University of Florida Whitney Laboratory for Marine Bioscience. Using genomics and computational approaches, the scientists...

Team from MBL, West Point uses new imaging technology to 'see' camouflaged marine animals in the eyes of their predators How could a colorblind animal know how to change its skin color to blend into its surroundings? And what will the animal's predator "see," looking at its prey before and after it hides? These provocative questions are addressed in article published today by a collaborative team from the Marine Biological Laboratory (MBL) in Woods Hole, Mass., and the U.S. Military Academy...

Low frequency sound causes lesions in sensory organs of squid, octopus and cuttlefish Noise pollution in the oceans has been shown to cause physical and behavioral changes in marine life, especially in dolphins and whales, which rely on sound for daily activities. However, low frequency sound produced by large scale, offshore activities is also suspected to have the capacity to cause harm to other marine life as well. Giant squid, for example, were found along the shores of Asturias, Spain in...

The evolutionary history of the Thaumoctopus mimicus lineage reveals the steps it took to become a master of disguise Paul the Octopus"”the eight-legged oracle who made international headlines with his amazingly accurate football forecasting"”isn't the only talented cephalopod in the sea. The Indonesian mimic octopus, which can impersonate flatfish and sea snakes to dupe potential predators, may well give Paul a run for his money when it comes to "see-worthy" skills. By creatively...

A study by researchers at the University of Toronto and the Royal Ontario Museum sheds new light on a previously unclassifiable 500 million-year-old squid-like carnivore known as Nectocaris pteryx. "We think that this extremely rare creature is an early ancestor of squids, octopuses, and other cephalopods", says Martin Smith of U of T's Department of Ecology and Evolutionary Biology (EEB) and the Department of Natural History at the ROM.  "This is significant because it means that...

Remarkable Strategy Evolved to Avoid Predators On the open sand plains of the Caribbean seafloor, where soft-bodied animals are routinely exposed to predators, camouflage can be key to survival. Perhaps no group of animals is quite as adept at blending in with its surroundings as cephalopods, who along with relatives the cuttlefish and squid, have evolved a unique skin system that can instantaneously change their appearance. In the February 2010 issue of The Biological Bulletin, MBL Senior...

Breeding program offers new opportunities to understand a little-studied species, and introduce the public to these fascinating creatures Anchored to an algae-covered rock in a 120-gallon tank at the California Academy of Sciences' Steinhart Aquarium, a cluster of inky-colored cuttlefish eggs is beginning to swell"”evidence of success for the Academy's new captive breeding program for dwarf cuttlefish, Sepia bandensis. The program, pioneered by Academy biologist Richard Ross, is the...

Chemicals produced by humans have been found in deep-sea squid and other creatures, further evidence that contaminants make their way deep into the marine food web, scientists said Monday. Researchers found a variety of chemical contaminants in nine species of cephalopods, which include octopods, squids, cuttlefishes and nautiluses. These species are food for dolphins, narwhals, killer whales and other toothed whales. The researchers collected nine species of cephalopods up to a...

Contamination of the deep oceanic food web is occurring, new study reportsNew evidence that chemical contaminants are finding their way into the deep-sea food web has been found in deep-sea squids and octopods, including the strange-looking "vampire squid". These species are food for deep-diving toothed whales and other predators.In a study to be published in the journal Marine Pollution Bulletin, Michael Vecchione of NOAA Fisheries' National Systematics Laboratory and colleagues Michael...
