A month after an orca, a new cetacean observed in the Seine

“At this stage, the cetacean has not passed into fresh water and its state of health seems correct. Increased monitoring is necessary to ensure that it goes back to sea on its own”, writes this Thursday evening on Twitter the NGO Sea Shepherd France.

At the end of May, an orca had been spotted in the Seine, between Le Havre and Rouen. This Thursday, June 30, it is a new cetacean which was observed between the Normandy bridge and the Tancarville bridge, indicates in a press release the Prefecture of Seine-Maritime.

“The prefect brought together all the institutional actors concerned as well as the association of the study group for cetaceans of the Cotentin and marine mammals of the Channel Sea (GECC), the organization Sea Shepherd France and the observatory Pelagis“, can we read.

The NGO had published in the evening several images of the animal, which “could be a whale”, indicating “that at this stage, the cetacean has not passed into fresh water and its state of health seems correct.”

A monitoring system put in place

According to the prefecture, “the animal observed moves slowly but with powerful movements, and appears to be in good physical condition. If it is confirmed that it is indeed this species, it is not uncommon to observe isolated specimens in coastal areas where the animal is able to feed, including in an estuary.”

A device for observing the animal, piloted by the GECC, has been set up, say the authorities. In addition, ships are prohibited from approaching the mammal within 100 meters.

The prefect of Seine-Maritime “invites witnesses to report any observation of the mammal”, via the contacts of the GECC (by telephone at 07.66.17.50.48 or by email at [email protected])
