Pheasant
A handsome gamebird, the pheasant is an introduced species that has settled here with little problem. It can be spotted in its farmland and woodland habitats, although you'll probably hear the loud, croaking call of the male before you see it.
Pheasant's-eye
Once considered a weed of cornfields, the Pheasant's-eye was nearly wiped out by intensive agricultural practices. Today, it can be found in deliberately seeded areas, and on roadside verges and waste ground.
Phosphorescent sea pen
This colonial creature looks like an old-fashioned quill - that's where the name sea pen comes from.
Piddock
Piddocks are a boring bivalve. No, we don't mean dull... we mean that it bores into soft rock, creating a burrow. In fact, they're the opposite of dull - they glow in the dark!

Pike
Famously predatory, the long, slender pike will lurk among the vegetation of a river or lake, bursting out with ferocious speed to catch its prey. Look out for it across the UK.
Pill woodlouse
The defensive mechanism of the pill woodlouse is very recognisable - it curls itself into a tight ball, only showing its plated armour to its attacker. It is an important recycler of nutrients, feeding on decaying matter.
Pine marten
Largely confined to the north of the UK, the rare pine marten is nocturnal and very hard to spot. However, it can be enticed to visit a peanut-laden birdtable.
Pineappleweed
Pineappleweed is an introduced species that has become a widespread 'weed' of disturbed ground, such as pavements and roadsides and gardens. It has feathery leaves and yellow flower heads.
Pink sea fan
Did you know we have colourful corals in UK seas? Pink sea fans are a type of horny coral - related to the sea fans found in the tropics. Don't be fooled by their name though, pink sea fans can actually be pink, orange or white.
