Rock pools, coastlines, and the shallow seas surrounding the UK. This page is part of our GCSE Natural History preparation, focusing specifically on UK native species and environments.
Wildlife in this Habitat
The marine world covers over 70% of the Earth, spanning from rocky UK shorelines to the darkest ocean depths.
UK Coastal Birds & Mammals
Grey Seal
Heavy, blubbery mammals that haul out on UK beaches to rest and pup.
Orca
Highly intelligent apex predators, with a small pod living off the Scottish coast.
Dolphins in UK Waters
Acrobatic marine mammals often seen riding the bow waves of boats.
Seagull
Herring Gull
Opportunistic scavengers highly adapted to coastal (and urban) life.
Oystercatcher
Distinctive black-and-white wading birds with bright orange beaks.
Puffin
Charismatic seabirds with colorful striped bills that dive for sandeels.
Cormorant
Dark diving birds often seen holding their wings out to dry.

Common Limpet
Sea snails that clamp onto rocks with incredible force.
Beadlet Anemone
Jelly-like predators that survive the low tide by pulling their tentacles inside.

Global Deep Sea Wonders
Blobfish
A deep-sea fish that relies on its gelatinous body to float without a swim bladder bursting.
Blue Whale
The largest animal to have ever lived on Earth, feeding on tiny krill.
Giant isopod
Enormous, prehistoric-looking scavengers of the ocean floor.
Vampire squid
Mysterious deep-sea cephalopods that turn inside out to defend themselves.
Gulper Eel
Bizarre fish with massive, pelican-like mouths to swallow large prey.
Dumbo Octopus

Global Arctic Marine Life
Walrus
