How Does The Swim Bladder Affect Hearing In Cichlid Fish?
2012-08-08 11:35:57

"Sound vibrations are transmitted to the inner ear via anterior extensions of the swim bladder or via bony ossicles", the biologist Tanja Schulz-Mirbach explains how swim bladders may serve for hearing. The hearing sensitivity improves considerably in this way. The anterior part of the swim bladder functions in specialized fish species similar to an ear drum. Up to now the effects of the different swim bladder morphologies have not been investigated in detail in cichlid fishes. The...

Fish-saving sound threshold recommended for pile driving projects The rise of ocean infrastructure development to tap energy sources such as tides, offshore wind and natural gas will require more pile driving, the practice of pounding long, hollow steel pipes called piles into the ocean floor to support energy turbines and other structures. But pile driving creates loud, underwater booms that can harm fish and other marine animals. Many scientists and regulators have assumed that...

Scientists say they have captured a live deep-sea fish and three shrimp species at a record depth of 2,300m on the hot vents of the Mid-Atlantic Ridge. A new trapping device has been developed that allows recovery of live animals under their natural pressure at greater depths than previously achieved. The researchers hope to be able to transfer the animals into an experimental lab to study their normal biology. "Pressurized recovery has been around for the past 30 years, but this is the...

Telescopefish are small, deep-sea aulopiform fish comprising the small family Giganturidae. There are just two known species, both within the genus Gigatura. Though rarely captured, they are found in cold, deep tropical to subtropical waters worldwide. These fish are understandably named for their bizarre, tubular eyes. The genus name Gigantura is in reference to the Gigantes, a race of giants in Greek mythology"”coupled with the suffix oura, meaning "tail", thus Gigantura refers to the...

The Toadfish are a type of ray-finned fish often found on the sand and mud bottoms of coastal waters worldwide, notable for somewhat broad heads and drab coloration reminiscent of terrestrial toads, as well as for the ability of the males of some species to "sing" using their swim bladders. They are classified as the sole family Batrachoididae of the order Batrachoidiformes, and include about 70 species in 19 genera, among them the common oyster toadfish, Opsanus tau. Their spines may inflict...
