The porpoise thrives in the waters of the English Channel in the spring.
This cousin of the dolphin is the most represented mammal, especially in this season when the numbers are the most important.
In turn, the number of strandings is also higher.
Unfortunately, since the beginning of April, the mortality of these cetaceans is "unusual in Calvados", describes the Pelagis observatory, based in La Rochelle, in charge of their expertise.

After Ouistreham, Merville-Franceville and Cabourg, it was Hermanville-sur-Mer's turn to find a dead porpoise on its beach on April 11.
An individual brought back by the tide, deceased for several days.
"21 animals were counted between April 1 and April 15," said the observatory.
A figure "higher than in previous years".
In fact, seven porpoises were stranded in April 2019, and only five in 2020.
What happens to cetaceans?
Scientists examine the remains to determine the circumstances of their death.
“All the animals were in good physical condition (…).
Several showed traces of capture in fishing gear ”.
Accidental captures can indeed occur.
Deaths, a priori, therefore unnatural, that Pelagis teams will seek to explore.
Until then, in the event of a macabre discovery on the beach, it is advisable to alert the authorities or municipal services so that the remains can be taken care of.
