Small, smaller, smallest -- The plight of the vaquita

A similar species is in the Bay of Fundy which gets caught in seine net weirs ("works") on Grand Manan Island, NB I was told by a Guelph University researcher. A small harbor porpoise or "skunkwahagen" (a striped dolphin, or after a distant cousin Nolan of whom a Passamaquoddy said swam like one). They were doing DNA studies of North Atlantic "right whales" (right because harpooned they float rather than sink) in their nursery there near Campobello and Grand Manan islands, taking DNA samples with a crossbow and rope attached arrow for taking small skin plugs, before they migrate to Florida. They "dolphins" were often shot in the weirs as they got entangled in the net, and someone was trying to develop a net that would let them free without letting the whole catch go out of the net strung wooden poles of the large weirs.
