Pink waxcap
This beautiful pink fungus appears in late summer and autumn.
Pink-footed goose
The pink-footed goose is a winter visitor to the UK, feeding on our wetland and farmland habitats. About 360,000 individuals spend the winter here, making it a really important destination for this bird.
Pintail
When spotting the pintail in winter, look out for the fabulous, long tail feathers that characterise it. This dabbling duck feeds at the water's surface, rather than diving for food.
Plaice
Plaice is a common sight all around our coasts - if you can spot it! They are extremely well camouflaged against the seabed and can even change colour to better match their surroundings.
Planaria
Planaria are flatworms in the phylum Platyhelminthes with amazing regeneration abilities giving them the title 'immortal under the edge of a knife'. There are many different species that inhabit freshwater, marine and terrestrial ecosystems.
Pochard
The once-common pochard is now under threat because its populations are declining rapidly. The UK is an important winter destination for the pochard, with 48,000 birds visiting our wetlands and coasts.
Porbeagle shark
The porbeagle shark is a member of the shark family Lamnidae, making it one of the closest living relatives of the great white shark.
Porcelain crab
Look out for this tiny crab under rocks and boulders on rocky shores - you'll have to look closely though, they're pretty well camouflaged!
Porcelain fungus
The shiny, translucent porcelain fungus certainly lives up to its name in appearance. It can be seen growing on beech trees and dead wood in summer and autumn.
Portuguese Man O'War
Despite appearances, this weird and wonderful creature is not a jellyfish! They're sometimes found washed up on our shores after westerly winds. Look but don't touch - they give a very nasty sting.
Primrose
In mild years, the spring-flowering primrose can appear as early as December. Look out for its pretty, creamy-yellow flowers in woodlands and grasslands.
Privet hawk-moth
With a torpedo-shaped body and long, narrow wings, the privet hawk-moth is a striking garden visitor. But the caterpillars really stand out: lime-green, with purple streaks and a black hook at the tail end.
