One of my favorite creatures in the world is the dolphin. So, here are a few randoms on dolphins:
1. There are 32 species of dolphins, four types of river dolphins, and six types of porpoises.
2. The word "dolphin" is from the Greek word delphis, which is related to the word delphys, which means "womb." The word "porpoise" comes from an Old French word for "pork fish" -- porpais.
3. A dolphin can shoot air through its blow hole at speeds up to 100 miles per hour.
4. Dolphins will help fishermen by signaling them when fish are near and even shepherding the fish to the fishermen's nets.
5. Some dolphins have been able to learn and understand up to 60 words.
