Hearing rumours of a sei whale in Humberside this morning, which is very exciting. These are very rare strandings as they prefer deep off shore waters, we've only seen 3 in the last 22 years. The boys are on their way to investigate, and hopfully perform a post mortem.

Sei whales are the third largest Balaenopteridae and are up to 20m long they are filter feeders, enjoying the same diet as other filter feeders, consisting mainly of krill. They got hit hard by the hunting and were initally protected, however sadly they remain a part of the 'research' conducted by Japan. It can be fairly easy to confuse them with fin whales but an inside tip for you is that fin whales have asymmetrically patterened baleen, gray and white, while the sei whales is just white. They can shift as well, reaching 30 miles an hour but only for short distances, but compared to other species they are a bit rubbish are diving, only reaching shallow depths and rarely staying down for more then 15 minutes.

On Wednesday we had a report about a dead white beaked dolphin stranded at Druridge Bay Northumberland. Its very fresh and as it's a quite an unusual species, we have rallied the troops and it is being picked up for post-mortem. We generally only see around 10 strandings of white beaked dolphins each year, and they are normally in Scotland or Northern England.

I honestly think the white beaked is one of the most beautiful of the dolphins. They are distinguished by their very clear, white beak (as seen in the pic), which is nice and easy to remember.

The animal should be pm'd in the next few weeks, but results can take a little while to come back but I'll up date when I get them.

Massive thanks too Claire Carey and Iain from the Berwickshire and North Northumberland Coast European Marine Site who have been a great help with animal.
