SPECULATION is growing that a baby porpoise found on the beach at Scratby was attacked by a shark - a second attack off the East coast.

In December, a seal was fatally injured and washed up off Sheringham, and shark experts sparked a debate about how it had died.

Was a Great White Shark in the waters off Norfolk?

On Friday afternoon last week, the porpoise - three feet long - was discovered dead at Scratby, a huge hole in its side and gash mark on its body.

Reader Aileen Mobbs who took pictures of the dead animal said: “It looks a bit gruesome but it does look like a big bite mark with lots of little incisions on the fins and tail. I am no expert but after the article about the seal in North norfolk and seeing this bite mark you do have to wonder…”

And reader Chris Hogg of Scratby also took photographs of the gouged remains of the porpoise.

He said: “What I find more interesting relates to a story in the Mercury a couple of weeks ago concerning an incident concerning a bite mark in a seal. Thoughts were aired regarding a shark but it was dismissed with other explanations offered.

“However, I attach photos of the Scratby mammal body and ask you to notice the 'bite' out of the head. There are also 'teeth' marks around the bitten off dorsal and also the body above the tail.

“The body was in good condition and in fact there was signs of slight bleeding on the beach below the body. Looks like a bite to me and something with a very big mouth and razor sharp pointed teeth.

Have we a shark off Norfolk?”
