These findings indicate that MR (Marine Reserve) protection can result in more and bigger individuals soon after the establishment of the MR. Focused comparison tests did not reveal any relationship between rock lobster (Jasus edwardsii) or blue cod (Parapercis colias) size or abundance and either age or area of MRs.

The mangrove rivulus, also known as the mangrove killifish, is native to the Americas and is about five centimetres (two inches) long.

The fish has long been studied for its many unique features. It's the only vertebrate known to naturally self-fertilize, for example. In some populations, it can become a hermaphrodite, developing both male and female parts simultaneously, to produce clones of itself.

“This discovery gives us great hope that there is a future for Irrawaddy dolphins,” said WCS researcher Brian D. Smith, who led the study. “Bangladesh clearly serves as an important sanctuary for Irrawaddy dolphins, and conservation in this region should be a top priority.”

The scientists counted nearly 6,000 of the dolphins in the South Asian country’s Sundarbans mangrove forest and the adjacent waters of the Bay of Bengal.
