Family - Monodontidae  (Norwal & Buluga)  The family
Monodontidae consists of two unusual animals called narwhal and
the Beluga. They are both medium sized whales they are three to
five meters in length. They generally weigh around 1600 kg. They
generally live in the far North Pacific and Atlantic and in the
Arctic Ocean. They live on a carnivorous diet of fish, mollusks,
and small causations. Monodontidae live in schools with up to
100 of them each. They both have similar colors black, white,
and grey. Both of the species have a very high vocal range.
Narwhal and the Beluga both lack a true dorsal fin, but Narwhals
do have distinctive ridges on their backs. As you can see this
family has many interesting features.  Author: Max T
