Polly's dorsal fin with both our hands, keep our bodies' to the side of her, and she would pull us back into the crowd.With a squeal or two of excitement, my sister and Polly were swimming straight towards us. After her turn, it was my turn. My nerves got ahold and me and I asked the trainer once we were out in the middle of the pool how deep it was. “It is 25 feet deep. But don’t worry, as long as you have that life jacket on, you won’t sink.” “Ok,” I said. I grabbed Polly's dorsal fin, and we…

stepbrother’s soft voice made Anna’s fears vanish. She jumped into the water. Through the murk she could see the waterbird, a large relative of the goby fish, staring back at her. It was twice her size. When it rubbed its fins against her, she took hold of its dorsal fin, and it swam down into the black depths. Her heart raced and her breath became short. Before she inhaled the water, another waterbird swam alongside and kissed her with its giant algae-sucking lips, leaving a bubble filled…

The L-pod resident orcas were gliding past Henry Island in the San Juan Islands of Washington State. This sight reminded me why I was in the San Juans in the first place: to appreciate nature and do my part to protect it. I finally got to experience these natural beauties that I had heard oh-so-much about from the locals. The sea breeze flowed onto my face, and I appreciated the wonder of…

Great Whites have a torpedo-shaped body, pointed snout, gill slits, and dorsal and pectoral fins. Great Whites, like other sharks, have no gas filled swim bladder to keep them up like bony fish do. They must be swimming constantly or they will sink. Their structure proves that it is well built and they will probably be around for…

Not only does SeaWorld separate the mothers from their calves, but they also force incest among the whales. Like our own species, incest is seen as taboo to whales. Hargrove explained that one female whale Katina was mated with her son Taku, creating the calf named Nalani. Katina refused to accept Nalani after her birth. Another instance of this was with a whale named Kohana who bred with her uncle Keto two different times. Kohana rejected both of those offspring (Hargrove). It is clear that…

leading up to two other deaths. We don't know what the orcas are thinking or feeling we can only interpret what we see with our thoughts and opinions. It seemed obvious that keeping orcas in captivity led to behavioral issues. Many of the male dorsal fins were flopped over instead of straight, indicating that they were in distress. Female orcas were separated from their young orca calves causing the moms to get…
