Latest Diversity of fish Stories
A distinctive 200-million-year-old fish used a combination of jutting front teeth and pebble-shaped rear teeth to feed on bivalves and other hard-shelled creatures it could find from the sea floor, according to new research from the University of Bristol.
A newly-identified genetic association with facial asymmetry in ancient cavefish could shed new light into mysteries surrounding conditions such as cleft palate or hemifacial microsomia in humans.
Fishes account for over half of vertebrate species, but while groups such as mammals, birds and reptiles have been fairly well understood by scientists for decades, knowledge about relationships among many types of fishes was essentially unknown – until now.
Cichlid fish are more likely to accept immigrants into their group when they are under threat from predators and need reinforcements, new research shows.
New research by a team of North American scientists indicates that warmer water may cause shrinkage in average fish size and populations of fish stocks.
Analyzing over 200 scientific assessments of fisheries around the globe, the team found that populations of small fish such as sardines and anchovies were at least as likely to have collapsed at some point in the last 50 years as stocks of large fish.
Whether a fish likes to hunt down its food or wait for dinner to arrive is linked to the composition of its brain, a University of Guelph researcher has revealed.
What are the long-term evolutionary implications of prolonged fishing for the fish that humans and, perhaps more importantly, diverse ecosystems so depend on?
Using snorkelers and SCUBA divers is not the best way to monitor fish populations, if we want to know the evolutionary effects of overfishing.
Large size and a fast bite spelled doom for bony fishes during the last mass extinction 65 million years ago, according to a new study to be published March 31, 2009, in the Proceedings of the National Academy of Sciences.
The white-spotted puffer is found around coral reefs, sea grass, tide pools, estuaries, and lagoons. In the South-East Atlantic Ocean, Indo-Pacific Ocean, Red Sea, Japan, Hawaiian Islands, and also off the southern coast of California at a depth of up to 115 feet. The adult is semi-aggressive, territorial, and nocturnal, hiding during the day and feeding at night. When threatened, this fish will puff up to deter predators. The body of this puffer is covered in a poisonous mucus and can be...
The Spotted Trunkfish (Lactophrys bicaudalis) is a species of fish found in reefs throughout the Pacific Ocean and Indian Ocean as well as the south eastern Atlantic Ocean. It gets its name from the black spots it has covered over its yellow/golden body. Like all trunkfish in the Genus Lactophrys, the Spotted Trunkfish secretes a colorless ciguatera toxin from glands on its skin when touched. It is only dangerous if ingested. Predatory fish, as large as nurse sharks, can die as a result...
