Netted dog-whelks often bury themselves in the sand but stick up their siphon to detect carrion much further away! Females lay very distinctive clear egg capsules with tiny yellow eggs inside, which can be seen on seagrass, seaweed or under rocks.

This sea snail can look very similar to the often-overlooked Tritia nitida, another species of dog whelk. To help Identify these two species look at the opening of the shell- the aperture- as the colour of the shell above the opening can help with identification. If you are recording your sightings as part of a recording scheme, make sure to take clear photographs of the aperture to help verifiers confirm your sighting.

Sut y gall bobl helpu

Always follow the Seashore Code when rockpooling, be careful to leave everything as you found it - replace any rocks you turn over, put back any crabs or fish and ensure not to scrape anything off its rocky home. If you want to learn more about our rockpool life, Wildlife Trusts around the UK run rockpool safaris and offer Shoresearch training - teaching you to survey your local rocky shore. The data collected is then used to protect our coasts and seas through better management or through the designation of Marine Protected Areas.
