female 16m
speed
30 km / h
weight (=40 elephants)
adult 40 tn
at birth 2.5 tn
lowering depth
300 m
the hunting of these animals made them an endangered species. Since the nineteenth century, the original population was reduced by 90%. there are currently about 8000.
they produce offspring every three years on average which undermines their protection and only accounts for 3000 individuals, of which 20% have been recorded in Argentina jurisdiction.
How they breathe
Like all mammals, whales have lungs. It's theorized they were originally land animals that evolved and adapted to water.
Inspiration
Renewal of air to the lungs with each breath.
90% whale 10% human
blowhole
expels a water stream 5m high in a "v" shape.
the life cycle
they breed in winter in warm waters. In summer, they feed in cold waters. they have a calf every three years.

behaviors
jump could be for dislodging parasites.
lash
projection caudal fin probably a form of communication.
uprising headlong
this occurs when the whales are curious.
Live parasitic crustaceans called whale lice produce the white colored patches.
calluses
eye, ear and eyebrow
no dorsal fin
mouth
the color is usually black or dark brown
plump body and mottled
beards
instead of teeth they have barbs used for filtering food from water.

the upper end is attached to the jaw.
the bottom is fringed to sift food.
during the feeding period weight increases up to 40%. the stored fat allows them to survive the winters.
