Bowmouth guitarfish (Rhina ancylostoma)

The bowmouth guitarfish is a species of ray. This rare species occurs widely in the tropical coastal waters of the western Indo-Pacific.

This large species can reach a length of 2.7 m (8.9 ft). The jaws are heavily ridged with crushing teeth arranged in wave-like rows. Usually found near the sea floor, the bowmouth guitarfish prefers sandy or muddy areas near underwater structures.

It is a strong-swimming predator of bony fishes, crustaceans, and molluscs. This species gives live birth to litters of two to eleven pups, which are nourished during gestation by yolk. The International Union for Conservation of Nature (IUCN) has assessed the bowmouth guitarfish as Vulnerable because it is widely caught by artisanal and commercial fisheries for its valuable fins and meat.

The bowmouth guitarfish, often described as prehistoric in appearance, is considered by some scientists to be the ‘missing link’ between sharks and rays based on the ray-like placement of the mouth and gill openings, and disc shape of the front part of the body and the shark-like streamlined appearance of the rest of the body and the powerful tail.

Today, I have another bird that seems to come from Jim Henson’s brain. This one seems to be more from the Creature Shop than the Muppet workshop.
Shoebills get their name from their beaks’ resemblance to certain footwear associated with 19th century Dutch Farmers, and I think the comparison holds up in terms of looks. The comparison breaks down in terms of use: clogs are not typically used for stabbing and crushing small prey items in African wetlands.
I really need to learn how to embed videos from ARKive, because there is an amazing video of a Shoebill hunting Lungfish that really looks like the Lungfish version of Godzilla. Watch it, you won’t be disappointed.

HUGGERS… meet the Shy Shark!  THIS IS A THING!  THIS IS REALLY A THING….! 

450 millions years of evolution and 'if i can't see it, it can't hurt me' is the best they could come up with!  WAY too adorable!  

You know, there are so many other jawsome sharks out there - shark week shouldn’t just focus on the white shark.  I love a good breach as much as the next shark lover, but these guys are too cute!  <3

little shy sharks.
