Ojala que sea ayudarte. I hope that I can help you.
Here are some differences between a whale (ballena) and an orca
A whale (ballena)
- has no teeth but instead has baleen plates which it uses to sieve water
from small food items like krill and school fish
- baleen whales are larger than dolphins or most other toothed whales
(except for sperm whales)
- baleen whales have two blowholes
- baleen whale calves stay with their mothers for a year or two usually,
but they are not usually found in larger permanent associations. Some
species of baleen whales do feed together in loose associations.
- most of the baleen whales have short or no dorsal fins
An orca
- has teeth and can eat larger fish, seals, sea lions, dolphins and even
whales, although it has to hunt in groups to catch larger items
- orcas are actually dolphins, the largest members of the oceanic dolphin
family
- orcas, like all other toothed whales and dolphins, have only one blowhole
- orcas are very social animals, travelling around with their mothers,
sometimes for life, and spending a lot of time with their close relatives
travelling in groups of up to 50 or more
- orcas have tall dorsal fins (especially the mature male, but also the
female fin is large compared to body size)
