What strange creatures. I couldn’t find any photographs of a baby bottlenose whale, so this is my artist interpretation. Genuinely want to see an actual photograph of a newly-born bottlenose whale tho

What a wonderful piece, I love those colours. Gives a real mystical feel to it.. this should be in a book or something ♥ As for the baby bottlenose whale - there are pictures!

Note that there’s some discoloration due to post-mortem darkening. Here’s a cute little live baby, swimming with mom! You can really see how much more starkly marked they are than the adults, especially with their cute creamy melons (photo © Sascha Hooker)

When they get a bit older they turn to the ‘chubby baby’ phase; the neonate twofold colour pattern fades in favour of a more adult-looking plain brownish grey (photo © Gudmann on Flickr)

Note though that while they are still babies, they are already 5 metres (16.5 ft) long and weigh some two thousand kilos (4400 pounds). These guys are HUGE.

A bunch of beaked whales

I did mention I got to paint a lot of beaked whales, right? ;) After the bottlenose whales here are, well, the others. I thought it was nice to put them all together, really makes you appreciate the wonderful diversity within this big family (and it saves you from ‘a beaked whale a day’ for the next 1.5 weeks). There’s too many to all discuss individually but I have some favourites:

Shepherd’s beaked whale was a joy to paint as they are one of my favourites. Their markings are so beautiful, and they are also unique in being the only beaked whale to have a full set of teeth. For very long their colour pattern was unknown (and oft presumed to have this streaky pattern) until in 2006(!) their real colouration was formally described. They are a beautiful, elegant and unique looking species.

Sowerby’s beaked whale provided a similar ‘aha’ erlebnis for me. Often illustrated as a medium gray throughout (which is certainly fitting for the females) some interesting photographs of adult males showed a rather distinctive light blaze between their blowhole and dorsal fin. In some males it was very subtle, but others had almost as much contrast as a Layard’s beaked whale - I chose to illustrate something in the middle. Very interesting and something I hope will be the subject of further study. Males and females also have funny white lips.

Ramari’s beaked whale can’t be overlooked as it is the youngest member of the family: only described three months ago, in October 2021. Previously known as the southern form of the True’s beaked whale, analysis proved they were a species all of their own. Very happy to have painted this one too, as the mysterious southern True’s with their shining white peduncles always intrigued me.

And lastly, I can’t not mention Blainville’s beaked whale becausetake a closer look at that snout. Any whale whose mouth somehow ends up above their eyes is worthy of an extra look I think. And the Layard’s beaked whale because they have always been my number 1 favourite beaker.

Phylogenomic Resolution of the Cetacean Tree of Life Using Target Sequence Capture

Cetaceans (whales, dolphins, and porpoises) have undergone the most dramatic morphological transformation of all mammals, having originated from a clade of terrestrial even-toed ungulates (like cattle, hippopotamuses, pigs, and more) over fifty million years ago. As a result of such an interesting and diverse evolutionary history, cetaceans have long been important and insightful subjects of numerous studies.

Until recently, the higher-level relationships between the cetacean families have taken precedence in research, leaving the systematics and lower-level relationships both under-explored and unresolved. 

New research from Systematic Biologysought to rectify this gap in knowledge by combining data from >38,000 exons with existing sequences from 11 cetaceans and seven outgroup taxa, producing the first comprehensive comparative genomic dataset for cetaceans.

Enrich your knowledge further by exploring a more holistic insight of the genetic intricacies within cetacean families and discover new clarifications of the contentious relationships among particular species.
