The Westcountry has been identified as a hotspot for jellyfish sightings in a new report which analyses where and when the creatures appear.

The University of Exeter study – published in the Journal of the Marine Biological Association – was based on more than 5,000 jellyfish sightings, of eight different species, sent to the Marine Conservation Society (MCS) between 2003 and 2011.

The coasts of Devon and Cornwall were identified as hotspots for both the diversity of species seen and in what numbers.

“Our survey puts jellyfish on the map in the UK. In this latest paper we show where and when these species now occur throughout UK coastal waters,” said Peter Richardson, biodiversity programme manager for the MCS.

“The last time the national picture was described was well over four decades ago, so this study provides a very timely update.”

The survey is the largest of its kind in the UK and has been attracting a growing number of sightings, with 1,133 reports last year.

Moon, compass, lion’s mane, blue and barrel jellyfish are the most common, according to the study. Other species include the mauve stinger and the Portuguese man of war and by-the-wind sailor which are close relatives of jellyfish.

More than 500 reports have already been made this year – mainly of barrel jellyfish.

Professor Brendan Godley, of the University of Exeter, said: “The remarkable number of barrel jellyfish reported from South West England this year is quite unusual, and at odds with what our report describes, previous years have seen hotspots for this species in West Welsh and Scottish waters. We’re not sure why, but the very mild winter probably meant more adults survived at depth, which will have returned to the surface in spring as waters warmed up.

“This year’s strange barrel jellyfish results highlight the importance of running the survey year in and year out to track these unusual events

and discover if they turn into trends.”

Dr Richardson said: “We still know relatively little about jellyfish, but given the economic impacts that large numbers of jellyfish can have on tourism, fishing, aquaculture and even power generation, we can’t afford to ignore them.

Bats 'fly by polarised light'

Bats use the pattern of polarised light in the evening sky to get their bearings, according to a new study.

As well as having unusual echolocation skills and their own magnetic compass, bats are now the first mammals known to make use of polarised light.

Other animals with this ability include birds, anchovies and dung beetles.

To make the discovery, published in Nature Communications, zoologists placed bats in boxes with polarising windows before watching them fly home.

Light waves normally wiggle all around their direction of travel, but when they pass through special filters - or are scattered by gases in the atmosphere - they can become polarised, so that the oscillations all line up.

"We initially didn't think that the bats would use polarised light," said the paper's senior author, Dr Richard Holland from Queen's University in Belfast.

Dr Holland was one of the scientists who discovered in 2006 that bats navigate by somehow sensing the earth's magnetic field - but that in-built compass needs to be calibrated. Other experiments showed that the calibration was happening at sunset, when the bats' day begins.

"We thought that surely, the sun's disc itself would be a more likely cue," Dr Holland told the BBC. But his team recently tested how bats responded when the sun's image was shifted by mirrors, and found no difference.read more
