Description The second largest animal on the planet, the Fin whale is only surpassed in size by the Blue whale. Despite its huge proportions they are amongst the fastest of the great whales and (unlike what I erroneously stated before) the true bearers of the nickname 'Greyhound of the sea'. They got this name from American naturalist Roy Chapman Andrews, "for its beautiful, slender body is built like a racing yacht and the animal can surpass the speed of the fastest ocean steamship." Up to a 100 ventral pleats line their throat and belly, allowing them to hold 60 000 kilos of water in their mouth - which is more than they weigh themselves.

This species is no doubt the best known asymmetrically coloured cetacean, even if many more species (such as the Dwarf and Antarctic minke whale, and even Bottlenose dolphins) also have uneven markings. On their right side Fin whales are remarkable light, with a great light grey rostral saddle and an all white lower jaw, Even the baleen are largely tinted yellow instead of black. However, with all previous whales facing left and for the sake of consistency, the much darker left side is shown here - which, I discovered, is no less intricately patterned than the right

I saw this species close up while whale watching in California a few weeks ago! I they get so curious of the boat! I also cant believe I saw their fluke! It was under the water, and you definitely dont realize the absolute size of those things till they're right next to you.

That sounds like such a cool encounter! How lucky that the whale was so curious about the boat too. And I can imagine they are much bigger in real life. I'd love to see one some day!

Woohoo! Love these guys! ^-^ This is amazing! Did you know that cetologists are contemplating whether or not they actually are closely related to the blue whale? Because there are a few indicators that prove otherwise. Or, wait... Am I thinking of the Bryde's or sei, perhaps? XD My mind's jumbled up right now.

Thank you so much! I know there's a lot of genetic/taxonomic debate going on within the Balaenoptera genus, although I have to admit I am not entirely certain which species are the focus of today's discussion. I do know that the Bryde's whale especially is a taxonommic headache, possibly comprising three or four species rather than just one, with doubts about which species the holotype belongs to. Complicated!

Yeah. Despite how much I adore taxonomy and try to understand it as best as I can, it can get more than a little challenging. :T

Gorgeous! So they have different coloration on both sides? That's neat

Yep! Like most Balaenopterid baleen whales they are asymmetrically coloured, being lighter on the right side than the left. Although it is a feature found in many species of the genus, it is most obviously present in the Fin whale and Omura's whale. They've got really gorgeous markings there, check it out: www.marineconservationresearch… www.freewhalepictures.com/imag… expeditiongallery.files.wordpr…

Oh my gosh, that is so cool! Didn't know that before, but I'm glad to have seen it. They're incredible

Another excellent work!  Reminds me, I need to get back to working on the whales I had planned!

Thank you very much! And that would be awesome Are you gonna do the baleen whales only, or all the whales?

Oh, just a few species planned.  I have a blue whale and some white sided dolphins  on canvas ready to paint, but it's huge so I have been putting it off.  And I'm planning another scene with gray whales, but it might take a while.

Oh that's be cool, I'd love to see that when it's done! I've always really enjoyed seeing great whales swimming together with the smaller cetacean species
