Colour anomalies in the Short-beaked common dolphin (Delphinus delphis)

As some of you may know I’ve a bit of a weak spot for everything weird with cetaceans: hybrids, deformities, colour anomalies - I love it all. And Short-beaked common dolphins are a gold mine in that last department. I don’t think any other species displays quite so many different anomalies, and with such frequency, as this one. Some, like the melanistic form, are almost ‘normal’ and quite stereotypical in their presentation. Others, like the dolphins in row 4, are highly unique. So earlier this year I made this poster documenting all know anomalies - initially just for fun but I ended up quite liking it! I hope you’ll have fun perusing the oddities of Delphinus delphis too. 

Most of these are based on several animals with similar anomalies. However, since the animals in row 4 are all so unique, here’s specific credits to their spotters: 4A was an individual stranded in the UK; 4B, D and E are all photographed by Lisa Steiner of Whale Watch Azores; 4C by Capt. Dave’s Dolphin Safari, 4F by Marilia Olio, and 4G was published in this article here.

Some dolphins (and a porpoise)

Here are some illustrations I made over the past couple of months for different people. The striped and common dolphin were most recent - for a sailing company in Portugal. Most are reworks of older illustrations though to be fair, any resemblance to the originals is rather lost. They kind of go along with the two Australian bottlenose dolphins I posted recently. I really like this style of illustration; a bit loose but still realistic. They’re super fun to make because they’re relatively quick and I don’t get hung up on polishing every last detail. I hope you like them too ♥

All of these illustrations - and many more - can be licensed for use by the way! For a full list of available illustrations, and some more info, check my website or contact me.

A posse of proper ‘phins
And another set of illustrations from last year. This time the “proper” dolphins - not too small, a regular dorsal fin, a good beak. Only the Risso’s is a bit out of line with their cute potheads but otherwise he was all alone. I had lots of fun with all of these. Spinners and Pantropcal spotted dolphin are a delight to draw always. This Pantropical spotted is from the Indian ocean, which tend to have fine black spots and very few white spots. The rough-toothed dolphin gave me some trouble - they’ve such odd proportions they’re hard to really nail down. I still don’t think he fully looks right, but that’s for a different illustration.

The common dolphins on top are very interesting to me: a good example of the diversity found within the single species of Delphinus delphis. Both are forms living around Southern Africa. The “longer beaked” form is larger, more elegant, and has gorgeous clear markings. They live off the Southeast coast, relatively close to shore. The “shorter beaked” form lives more to the west, in offshore waters. They are stouter and often with slightly vaguer markings. One day I’d love to see a study done on all the African forms of short-beaked common dolphins, they are so fascinating. If you move further up the west coast, around Angola, you’ll find a really strange form which is super dark and oddly proportioned. Wonder what’s up with those.

The Indian Ocean humpback dolphin is also an oddball, and a first for me. Love their cute faces and unique body shape. Not just the hump-back but also that strongly keeled peduncle. I hope you’ll enjoy them too!
