These animals are used solely for human entertainment. Orca whales are meant to be in the ocean, not in a concrete…

Cesar Chavez once said, “We need, in a special way, to work twice as hard to help people understand that the animals are fellow creatures, that we must protect them and love them as we love ourselves.” Keeping animals in captivity is not protecting them and loving them. Animals such as killer whales should be treated fairly but instead they are thrown into small tanks. Killer whales should not be kept in captivity due to the fact that they get inadequate care, they can become emotional and…

Sharks don’t fossilize well because they’re from the class of chondrichthyes meaning their skeletons are made of cartilage, a flexible connective tissue. This is one of the reasons why there is a disagreement over when the first shark first existed. However, shark teeth do fossilize well and sharks produce thousands of teeth in a lifetime. The oldest shark teeth date back to the Devonian Period about 400 million years ago and were found in Europe. Shark scales also fossilize well.…

New Zealand Killer Whales and Penguins What exactly are cetaceans? The Cetaceans family includes whales, dolphins, and porpoises. Even though the cetacean family depends on water or more specifically the ocean for survival, they are mammals just like we are.

Have you ever seen those cute little Whales doing tricks at places like seaworld? Has it ever crossed your mind that these whale could be hurting in that show bizz life? The thing is these creatures are way to smart, large, and very complex to be put in a small environment. The injuries that some people know of are from the trainers, but some don't even hear about the animal's injuries.

of the water which, in some cases, causes their dorsal fin to droop. Male dorsal fins can grow up to six feet tall. 100% of male whales and a smaller percentage of females can suffer from dorsal fin collapse. Research has shown that in the wild, orcas travel far and quickly and they dive through deep water, the water puts pressure on the fin which keeps the tissues straight and healthy. This helps the fin remain straight and upright. The orca’s fin collapses in captivity, again because of the…
