Paper catalogs whale shark movements off Madagascar

A new paper in the journal Endangered Species Research shows that the Indian Ocean island of Madagascar has emerged as a hot spot for whale sharks (Rhincodon typus). By using the global sightings database, Wildbook for Whale Shark researchers have identified 85 individual sharks, which do not seem to have come from other feeding areas in the Indian Ocean.

Hundreds of large dolphin pods are reported in the Chesapeake Bay Photo

Hundreds of large dolphin pods are reported in the Chesapeake Bay

Dolphin sightings in the Chesapeake Bay have been on the rise in the past few years, increasing from a sighting here and there to sightings of large pods daily. Dolphins were once regular inhabitants of the bay, but steadily decreased as pollution increased in the 20th century. Now that the water is cleaner than years past, submerged aquatic vegetation has rebounded, and fisheries are recovering, it has become the inviting space it once was for dolphin. Researchers have set up a website to track dolphin sightings. Through the website data they receive, it is estimated that there are thousands of dolphins residing in the bay during the warmer months.

Sharks prefer jazz music Photo

Sharks prefer jazz music

In a newly published study, scientists have shown that shark may prefer the regular beat of jazz music over classical music. Experts have long hypothesized that sharks associated the noise of a boat’s engine with food after many years of being fed. In this study, scientists trained port jackson sharks to follow music played at one end of a fish tank for a food reward. The results of the study illustrate a lot about what sharks are capable of.

Invasive rats have been successfully eradicated from Antarctic Island

A successful invasive species eradication program has rid South Georgia island in the Antarctic of rats. The efforts of the Scottish charity, South Georgia Heritage Trust, began in 2010 and just wrapped up after waiting two years after the last application of rodenticide. There are no trees on the island and the introduced rats were devouring species of birds that nest on the ground and are found nowhere else in the world. Rats were first introduced to South Georgia by sealers and whalers in the early 19th century.

Pregnant humpback whales surge near Antarctica

Scientists have seen a significant upswing in the number of pregnant female humpback whales in the Antarctic recently. Blubber samples over a six year period showed approximately 60 percent of females had high progesterone levels, an indication that they were pregnant. The scientists also have seen an increase in the number of calves born in recent years. Both signs are encouraging as humpback whales are at ten percent of their population from pre-whaling years.

In a new study scientists admit there is a lot to learn about mantis shrimp vision systems

In a newly published study on mantis shrimp, scientists admit “We’re nowhere close” to solving the mystery of their vision systems. In a study published yesterday in The Royal Society, scientists tried to get to the bottom of mantis shrimp vision systems once again by investigating gaze stabilization. Biologist Ilse Daly, with the University of Bristol in Britain, was the lead scientist on the study of peacock mantis shrimps. During the research Daly found the orientation of their eyeballs “doesn’t seem to have any bearing on their perception of space”.
