Marine sightings

Common SealWe have two new marine sightings forms that we have developed along with Jessi Jennings, La Société’s Marine Biology Section Secretary and Paul Veron of the Ornithology Section and well-known expert on our local sea birds.

If you are interested in sending us records, you can download a copy of the mammal, fish and jellyfish form here and the sea birds form here. These are editable forms so you can fill them in online or on a Laptop/tablet etc and email them to us. If you prefer to print either or both of them and fill them in by hand that works too, but you will need to send them to us!

Recording is important so that we can understand how marine mammals, birds and fish use our waters. Once we have more data, we will have a clearer idea of when and where they congregate and feed so that we can work with the States of Guernsey to help them survive and thrive.

The Whale and Dolphin Conservation Society has produced an excellent leaflet which provides handy identification tips for those recording marine mammals. A copy is available here.

We are aware that the behaviour of watchers has a major influence on animals. We recommend that all boats observe the following code of conduct watching seals, whales, dolphins and other marine wildlife:


KEEP your distance and use binoculars to get the best views. Never go closer than 200 metres to seals or seal haul-outs and 100 metres to whales & dolphins (200 metres if another boat is present).

PLEASE don’t over crowd. A maximum of three vessels should observe marine animals at any one time

NEVER drive head-on to, move between, scatter or separate dolphins.  If unsure of their movements, simply stop and put the engine into neutral.

PLEASE spend no longer than 15 minutes near the animals.

SPECIAL care must be taken with mothers and young.

MAINTAIN a steady direction and slow ‘no wake’ speed.

NEVER try to swim with, touch or feed the animals for your safety and theirs (remember they are wild animals). If animals want to come and see you they will – never pursue or harass them.

TOUCHING dolphins can be dangerous as they carry diseases that are transmittable to humans, including brucellosis.

DO NOT dispose of any rubbish or contaminants in the sea.
