Variability of the mitochondrial control region in populations of the harbour porpoise
, Phocoena, on interoceanic and regional scales.
Using drifting passive echolocation loggers to study harbour porpoises
in tidal-stream habitats.
Bottlenose dolphins and harbour porpoise
are not often seen at the same time: bottlenoses tend to scare off the smaller harbour porpoise
as they compete for food.
Organochlorines in Danish and west Greenland harbour porpoises
It is important to note that on mainland Portugal, the harbour porpoise

The Hebridean waters are home to the largest population of whales around the UK coast, with minke whales, bottlenose dolphins, harbour porpoises
, grey and harbour seals.
, for instance, suffer terribly in UK waters with incidental capture (drowning) in fishing gear claiming up to 10,000 of them a year.
Since the launch of the dedicated facility on the DFDS ferry in March, ORCA's community wildlife officers Rachael Forster and Ruth Coxon have already seen 38 white-beaked dolphins, two Harbour porpoises
, several grey seals and many bird species such as puffins, petrels and gannets, at various points between Newcastle and Amsterdam.
And up to 405 grey seals, 2,223 harbour porpoises
and 22 bottlenose dolphins are predicted to display 'milder' behavioural responses.

Scientists from Sea Watch Foundation came across grey seals, harbour porpoises
and a large group of bottlenose dolphins, while they were on a patrol last week.
