Rare angel shark in Anglesey waters

One of the World’s rarest sharks has been spotted swimming in our Anglesey waters!  The mysterios angel sharks (Squatina Squatina) were classified as being critically endangered in 2010, but sightings earlier this year suggest that a small population is living off the Anglesey coast.

There are 23 species of angel shark in total. They are also known as monk or monkfish by fishermen, although they are in fact a type of shark, which is noted by their use of fins. Angel sharks like to eat other fish, crustaceans, and molluscs. Most types grow to a length of 1.5 m (5 ft).

Other endangered species

There has been a “catastrophic” decline in insect numbers which, say scientists, “risks a total collapse in global ecosystems”.  “Love or loathe them, humans can’t survive without insects” says Professor Dave Goulson of Sussex University.
There has been a 2.5% annual fall in the mass of insects over the last 25-30 years, suggesting many could vanish within a century.  Some of the insects whose decline has been noted include: dragonflies, ground beetles, leafhoppers, bumble bees, butterflies and moths.
Alongside the decline in insects, other species are also declining – including hedgehogs (down some 29 million since the 1950’s), turtle doves which have lost all but 7% of their population and are now at risk of extinction and skylarks whose population has declined by 55% since 1970.
But, as we showed in the last edition, there are some species that are making a remarkable come back, having been facing near extinction:  badgers, otters, pine martens, polecats, stoats and weasels are thriving thanks to conservation controls.
