A ROV (remote operated vehicle) owned and operated by the oil company Shell have caught video of a very rare squid while filming a mile and a half (two and a half kilometers) underwater on the drilling site known as Perdido in the gulf of Mexico. The squid known as a Magnapinna squid has a unique look due to the fact that it has “elbows” on its arms. Little is known about these enigmatic squids that can grow to be between 5 to 23 feet (1.5 to 7 meters) long.
Wild-caught pets are often recommended against, since the harvest of wild caught specimen may deplete wild populations. In the Brazilian rainforest, the harvesting of popular aquarium species such as cardinal tetras have however helped prevent deforestation and made it possible for local residents to earn a living without resorting to logging, mining, cattle ranching, and slash-and-burn agriculture.
Rare coral species may be saving themselves from extinction by hybridising with other coral species, says Australian scientist Zoe Richards. Richards and his colleagues have studied 14 rare and eight common coral species of the genus Acropora in the Indo-Pacific.
In order to find out more about hybridisation among corals, the team did a phylogenetic analysis using the highly polymorphic single-copy nuclear Pax-C 46/47 intron and the mitochondrial DNA (mtDNA) control region as markers.
Vast amounts of creatures looking like jelly balls have begun to appear off the eastern coast of Australia, and researchers now suspect that these animals may help slow down global warming by moving carbon dioxide from the atmosphere to the ocean floor.
The proper English name for this “jelly ball” being is salp. A salp is a barrel-shaped free-floating tunicate that moves around in the ocean by contracting and relaxing its gelatinous body….
A six-month long investigation by the Florida Fish and Wildlife Commission (FWC) has led to the arrest of seven adults and one juvenile in Tampa. The arrested persons are believed to have been involved in various illegal activates concerning marine life, including catching protected sharks, sea horses, peppermint shrimp and bay scallops in Floridian waters, and exporting illegally obtained marine life to Europe. They are also suspected of having sold bait fish and bait shrimp as food for human consumption.
A new subfamily has been created within the catfish family Loricariidae, the largest family of catfish and currently home to over 700 described species. The new subfamily has been named Otothyrinae and its members include the genera Corumbataia, Epactionotus, Eurycheilichthys, Hisonotus, Microlepidogaster, Otothyris, Otothyropsis, Parotocinclus, Pseudotothyris, and Schizolecis.
The U.S. Bureau of Reclamation is now carrying out tests in hope of finding out if bacteria can aid them in their struggle against invasive mussel species that are threatening to spread across the West’s waterways.
During the summer of 2008, a preliminary test was executed at Davis Dam on the Colorado River at Laughlin in Nevada.
Thanks to the efforts of local resident Pak Dodent, coral destroyed around Sumatra by the 2004 tsunami is now making a remarkably recovery.
Dodent lives on the island of Pulau Wey off the north coast of Sumatra and the narrow channel between his small village Ibioh and a nearby island was particularly devastated by the enormous forces unleashed by the tsunami.
A study published in the online scientific journal PLoS Biology on October 27 with the provocative headline “Dams make no damn difference to salmon survival” is now being questioned by a number of scientists, including several co-authors of the study.
According to the study, young fish running the gantlet of dams on the Snake and Columbia rivers did just as well as youngsters in an undammed river….
Otto the Octopus, an eight-armed resident of the Sea Star Aquarium in Germany, baffled his caregivers by deliberately short-circuiting an annoyingly bright light that shone into his otherwise cosy aquarium.
According to staff, the marine exhibition began to suffer from mysterious blackouts to which the puzzled electricians could not find any reasonable explanation. This prompted the aquarium staff to take shifts sleeping on the floor in hope of solving the mystery. “It was a serious matter because it shorted the electricity supply to the whole aquarium that threatened the lives of the other animals when water pumps ceased to work,” a spokesman of the aquarium explains.
According to University of Queensland marine biologist Professor Ove Hoegh-Guldberg, recipient of the prestigious Eureka science prize in 1999 for his work on coral bleaching, sea temperatures are likely to rise 2 degrees C over the next three decades due to climate change and such an increase will cause Australia’s Great Barrier Reef to die.
Hoegh-Guldberg’s statement is now being criticized by other scientists for being overly pessimistic, since it does not consider the adaptive capabilities of coral reefs.
