Latest Fish anatomy Stories
A SCUBA expedition in Australia and New Zealand to find the rare embryos of an unusual shark cousin enabled American and British researchers to confirm new developmental similarities between fish and mammals.
Fish and some amphibians possess a unique sensory capability in the so-called lateral-line system.
For years scientists have observed the deleterious effects of rising levels of carbon dioxide in the oceans on shellfish and corals.
Most fish rely primarily on their vision to find prey to feed upon, but a University of Rhode Island biologist and her colleagues have demonstrated that a group of African cichlids feeds by using its lateral line sensory system to detect minute vibrations made by prey hidden in the sediments.
The genetic toolkit that animals use to build fins and limbs is the same genetic toolkit that controls the development of part of the gill skeleton in sharks.
A paper in this week's PLoS Biology reports that a common gene regulatory circuit controls the development of all dentitions, from the first teeth in the throats of jawless fishes that lived half a billion years ago, to the incisors and molars of modern vertebrates, including you and me.
By Longenecker, Ken Abstract: Estimating body size of fishes from remains recovered from piscivores, archaeological sites, and sedimentary deposits is desirable but rarely accomplished because the relationships between the size of a fish and its durable anatomical structures are largely unknown.
By Luntz, Stephen Increasing ocean acidity as a result of carbon emissions may be making it hard for fish to form symmetrical otoliths (ear bones), creating a further threat to the health of coral reef ecosystems as fish with asymmetrical ear bones struggle to find their way to the safety of coral reefs.
By Duffin, Christopher John Abstract The folklore associated with fish otoliths is traced from classical times to the present day for the first time.
Peruvian archaeologists displayed more than 400 seized shark teeth, shells and fish fossils as old as 12 million years on Friday, saying customs officials have already made twice the number of such seizures this year than they did in 2006.
Balistidae is a family that contains about forty species of triggerfish that can be found in tropical and subtropical waters around the world, although the greatest variety of species can be found in the Indo- Pacific region. Most triggerfish species can be found in shallow water in coastal areas, especially near coral reefs, although some can be found living in the open ocean. While some species are edible, like the grey triggerfish others are not recommended for human consumption, including...
The Asian Arowana (Scleropages formosus) comprises several phenotypic varieties of freshwater fish that are distributed geographically across Southeast Asia. As they are native to Southeast Asia, Asian Arowana inhabits blackwater rivers and slow moving water flowing through the forested swamps and wetlands. The adults feed on other fish while the juveniles feed on insects. These popular aquarium fish have special cultural importance in areas that are influenced by the Chinese culture....
The Butler’s Frogfish (Tathicarpus butleri), known also as the blackspot anglerfish, is a rare species of frogfish belonging to the family Antennariidae. The only member of its genus, this species is the most derived member of its family, representing a separate lineage from all other frogfishes, leading to some consideration of it being placed in its own family. It can be found off the southern coast of New Guinea, and along the coasts of Western Australia, the Northern Territory, and...
The psychedelic frogfish is found only around Ambon Island, Indonesia at depths of 16 - 23 feet in coral rubble about 66 feet from the shoreline. This fish was discovered in 1992 amongst a shipment of assorted fish that was delivered to the Dallas Aquarium at Fair Park. But was not observed or photographed in the wild until 2008. The psychedelic frogfish was named one of the top ten new species discovered in 2009 by Arizona State University's International Institute for Species Exploration...
The little tunny is found widespread in temperate and tropical waters of the Atlantic Ocean, Black Sea and Mediterranean Sea. It is the most common tuna and is highly migratory, with a range from Cape Cod, Massachusetts to Brazil in the Western Atlantic. In the Eastern Atlantic it is found from Skagerrak to South Africa. The little tunny will form schools close to the shoreline, around inlets, and sandbars that can cover up to two miles. This fish prefers warm water and will migrate south in...
