Research by ecologists at Brown University found that faster water flow speeds promote greater diversity of invertebrate species on rocks under the ocean. The study showed consistent results across three regions, suggesting that water flow is a key factor in determining marine biodiversity.
Coral reefs are surprisingly noisy places with fish and invertebrates producing clicks and grunts that provide useful information about the state of the reef. Healthier reefs were found to be louder, with a clear association between overall noise level generated and the amount of living coral.
Researchers found that male African cichlid fish exhibit a fear response when fighting their own reflections, characterized by increased activity in the amygdala region of the brain. This discovery suggests that fish may have more complex cognitive abilities than previously thought.
Australian yabbies possess a remarkable capacity for facial recognition, studying found that they can identify and distinguish between individuals. This ability is comparable to that of humans and some vertebrates, but rare in invertebrate species.
Researchers discover sea animals can spontaneously clone themselves, providing new insight into chordate evolution. The larvae of echinoderms form an outgrowth that pinches off and grows into a second, normal-looking larva, a process that was previously unrecognized.
In contrast to many other introduced species, most marine invertebrates increase in size after invasion. This size increase may have significant implications for the impacts of these species on native ecosystems. The study's findings highlight the need for further research into the effects of invasive species on non-native regions.
