The scientific name for a whale is Cetacea. There are so many different types of whales but the killer whale is the most endangered.
The Orcinus Orca also known as the killer whale is an endangered animal. These mammals eat octopus, sea birds, squid sea turtles, sharks, and more. The only impact on this type of whale is humans.
Considering that humans are the only impact on the killer whales we have a lot of ways that we are affecting the ocean and the whales them selves. One example of this would be that when the whale comes up to eat sips hit them or they get caught in nets or other things that have been thrown into the ocean.
