This small toothed whale weighs between 400 to 600 lbs on average. These operations usually catch and drown the critically endangered species in gillnets, resulting in a reduced population within the last few years.Among the 72 toothed whale species in existence (and among all whale species), the dwarf sperm whale is the smallest with a length of nearly nine feet. They would look quite similar to living dolphins or beaked whales, but there are several key differences. This condition is unlike what’s seen in living whales but similar to archaic whales.
