The attached photo is of some strange fungus, which appeared in the garden earlier this month. Is it Myriostoma coliform?

No, it is the earthstar, Geastrum triplex, of the same group of fungi.

While working in my garden I spotted the thinnest worm I have ever seen. It was about 15cm in length.

It's a horsehair worm, probably the thunder worm, Mermis nigrescens, which comes out after rain but lives in the soil.

This black squirrel in my garden was quite unafraid and making chittering and chirping noises. I understand there have ben no sightings of black squirrels in Ireland.

I have found no reports of black squirrels in Ireland, though they are found in Britain. They are grey squirrels with a faulty pigment gene.
I recently came across an unusual isopod parasite on a mackerel caught in Galway Bay. About 2cms long, it belongs to the same isopod group as the woodlouse, and was identified by a biologist at the Oceanography Centre in Southampton as Nerocila orbignyi. Biologists would be interested in getting more reports of it.

We watched this 2m-long common dolphin swim directly towards the shore at Ballycotton. As it reached the slipway it turned east and swam very close to the shore for about 100m before a wave just washed it ashore. By the time we got to it about five minutes later, as far as we could see it was dead.

This seaweed covered one whole section of Dunlaughin beach, Ballyconneelly on October 18th. Amazing colour; can you identify it?
Ann Keogh, Oughterard, Co Galway
It needs a close-up to identify the species, but stranding of red seaweed is unusual; more usual are the brown kelps and wracks.
