BOTTLENOSE DOLPHIN
Anytime dolphins are spoken of, these babies are sure to come to mind. Quickies:
• They prey on mainly small fish and squid.
• They can travel at speeds of 18 miles an hour.
• They can make up to 1,000 clicking sounds per second! That’s insane!
• That blowhole of theirs is their nose.
COMMERSON’S DOLPHIN
This is probably not a picture that comes to your mind when you think ‘dolphin’. Quickies:
• These poor guys are hunted for crab bait.
• They have harlequin-shaped markings on their body.
• They’re only found on the southern tip of South America and an island off Africa.
• Live in groups of 1-3, but large schools are occasionally formed.
SPINNER DOLPHIN
Not the most famous dolphin out there, but a beautiful one. Quickies:
• They reside in tropical pelagic oceans all over the world.
• They are 1.7-2m long.
• It is unknown of their conservation status.
• They can be seen in schools from 5 to 200. But schools of 1,000 have been reported.

DUSKY DOLPHIN
And save the best for last, the Dusky Dolphin. I’m not sure why I love this over the others, but I do. Quickies:
• They inhabit the coastal regions below the Tropic of Capricorn all the way to the sub-Arctic.
• They have an all white belly.
• Schools of them can range from 20 to 300.
• They are a very acrobatic species.

I think the “Dusky” might be my favorite as well. They look elegant when they’re swimming.
Very cool! Congrats on the posting gig too. Guess I’ll be seeing you at Blogher with your mom.
1,000 clicking sounds per second, eh? I’m sure many beatboxers would be envious of that!
@Kelvin Kao: LOL! It’s like the Justin Timberlake of the underwater world.
Before Hurricane Ike my family and I would ride the Galveston Island ferry and watch the dolphins swim beside it. I loved seeing them!
Nice work Cassidy!
Yes, great work, Cassidy! I learned things I didn’t know about these different types of dolphins.
You know . . I actually learned something today. Thanks Cassidy! Keep up the great work!
That’s my GIRL! And look at all my buddies who came out and said hi – I’m the luckiest blogger in the world to have such a great kid and such great friends!
Great job, Cassidy. Your mom is very proud! Keep up the good work.
I cant wait until we can take our girls to see this. They would probably flip out from excitement and wonder. I didnt know there were so many types of dolphins.
Thank you for the great information, pics, and the film was awesome! I am emailing this site to my family and saving it for the next time my grandson visits. I’ve always told him how awesome dolphins are. He loves dolphins as well. Everyone would love to see this.
Can’t wait to come back again next year – LOVE Sea World I did not notice the bubbles last year, but will definately look for them this year……
They are not just only beautiful they are intelligent!
Dolphins & Shih tzu puppies! You rock!
i don’t see what the big deal is. it might be like whistling. some dolphins can do it and some cannot do it. hard to believe this behavior hasn’t been noticed before.
