ScienceDaily (Mar. 2, 2012) — Shark fins are worth more than other parts of the shark and are often removed from the body, which gets thrown back into the sea. To curtail this wasteful practice, many countries allow the fins to be landed detached from shark bodies, as long as their weight does not exceed […]
By Jonathan Amos Science correspondent, BBC News, Salt Lake City Marine biologists are starting to get a good idea now of how squid hear and how they react to sounds in the ocean. It is only recently that scientists have come to accept that cephalopods have any auditory capability at all. But new experiments […]
ScienceDaily (Feb. 26, 2012) — Not all that glitters is gold. Sometimes it is just bacteria trying to get ahead in life. Many sea creatures glow with a biologically produced light. This phenomenon, known as bioluminescence, is observed, among others, in some marine bacteria which emit a steady light once they have reached a certain […]

Fogcityjournal.com In November 2006, Washington Post writer Juliet Eilperin headlined, ” World’s Fish Supply Running Out, Researchers Warn,” saying International ecologists and economists believe “the world will run out of seafood by 2048″ if current fishing rates continue. A journal Science study “conclude(d) that overfishing, pollution and other environmental […]

Calypso while anchored on the lee side of Glover’s Reef in Belize, Jacques Cousteau told Phil Dustan that he suspected humans were having a negative impact on coral reefs. Dustan — a young ocean ecologist who had worked in the lush coral reefs of the […]
ScienceDaily (Jan. 24, 2012) — Scientists at USC have uncovered evidence that even when hydrothermal sea vents go dormant and their blistering warmth turns to frigid cold, life goes on. Or rather, it is replaced. A team led by USC microbiologist Katrina Edwards found that the microbes that thrive on hot fluid methane and sulfur […]
Abstract The parrotfish Sparisoma viride often grazes live coral from edges undermined by the Caribbean encrusting and excavating sponge Cliona tenuis. To test whether parrotfish biting action has an effect on the dynamics of the sponge–coral interaction, we manipulated access of parrotfishes to the sponge–coral border in two species of massive corals. When parrotfish had […]
