A new species of striped Philippine butterflyfish -- the charismatic Roa rumsfeldi -- made a fantastic, 7,000-mile journey before surprising scientists with its unknown status. Live specimens collected from a depth of 360 feet escaped special notice until a single black fin spine tipped off aquarium biologists back in San Francisco. Deep-diving researchers from the California Academy of Sciences' Hope for Reefs team -- with genetic sequencing help from a parent-son team -- share their discovery of a fifth species of Roa this week.
A new study appearing in the journal Marine Ecology Progress Series has found that conserving fish diversity in Madagascar's coral reef systems may depend on maintaining fish biomass above critical levels, according to scientists from WCS (Wildlife Conservation Society) and ES Caribbean.
A new study based on the first global survey of marine life by scuba divers has provided fresh insights into how climate change is affecting the distribution of marine life. The research published in the journal Science Advances predicts that as the oceans warm fish -- which appear to be superior predators in warm water -- will extend their ranges away from the equator and cause a decline in the diversity of invertebrates such as crabs, lobsters, sea urchins and whelks.
Jaws, beware! Alligators may be coming for you, according to a Kansas State University researcher. A study in Southeastern Naturalist documents American alligators on the Atlantic and Gulf coasts are eating small sharks and stingrays. This is the first scientific documentation of a widespread interaction between the two predators.
Surprisingly low concentrations of toxic chemicals -- from fungicides to antidepressants -- can change the way some aquatic creatures swim and feed, according to new research. In addition, depending on the cocktail of toxins they can produce unexpected results.
A UCSB investigation of the different economic values of giant sea bass finds they are worth more alive as undersea wonders than as commercial catch.
Scientists recently discovered that some jellyfish in the Bay are quite different from their ocean cousins. This led scientists from NOAA and the Smithsonian Institution's National Museum of Natural History to declare them as two different species.
An international research team has undertaken the first in-depth investigation of the teeth of captive orca (killer whales) and have found them a sorry state, which raises serious concerns for these majestic mammals' overall health and welfare.
When evolving in environments where a lack of predators makes food scarcity the main survival challenge, guppy mothers gestate their young longer so that they are born more ready to compete for their meals.
Getting caught in fishing nets is a major cause of death for the increasingly endangered New Zealand sea lion, according to new research from the New Zealand's University of Otago and Massey University and the University of Toronto.
