The reason why this dolphin looks pink is because it's blood vessels were tight at birth. Also this is the amazon river dolphin. Their natural color is pink! They can only see a little bit because they are blind from the river water. This is the only dolphin to live in a river and not in salt water.
We couldn’t be more proud of the job Katrl is doing as a new mother, showing signs of protectiveness by steering her calf away from the sides of the habitat and helping to guide it into swimming position to conserve its energy reserves. #
Vaquita. This is the world's smallest dolphin and is from the Northern Gulf of California and Mexico. There are less than 200 vaquita dolphins left in the wild and the population is declining. The immediate threat to the dolphins is the use of gill nets deployed by fishermen.
This frilled shark is actually pretty rare and was photographed live in Japan in 2007. This is considered a “living fossil” with primitive morphology, such as a fixed upper jaw. The species feeds and hids in crevices and caves and apparently has the longest gestation period of any animal (3.5 years!).
