see, you wouldn't necessarily pick up on this, but beluga skulls (and most cetacean skulls in general) are pretty much

flat...

so what's going on up there? well, most of the beluga's head is taken up by soft tissue and a large organ called the melon, which is basically a big ol waterballoon of semiliquid fat!

(boob. it's a head boob.)

this organ is found in every toothed whale and dolphin species on the planet and it's INCREDIBLY important, because the melon is what lets them echolocate!

the actual sound-producing organ is inside their nasal passage of all places, which sits up behind there, but the melon is what's actually used to fine-tune the soundwaves into the laser-accurate pinpoints that dolphins and toothed whales are so famous for.

Bahlul ibn Marzuq was a rebel that freed Huesca from the tyrannical government of the Banu Salama with a huge popular support and established his own - short-lived - independent kingdom in the 9th century. A free territory from nowadays Nafarroa until the Mediterranean. 

Bahlul was the son of Marzuq ibn Uskara. Uskara is still how certain regions of Euskal Herria call Euskara nowadays, and it’s widely believed that Bahlul’s dad was of Vascon origin: literally, his name meant Marzuq, son of the Basque.
