Anteater anatomy

aslabnotes:

For the zoological illustration final, we were required to illustrate a fully fleshed out mammal as well as the full skeleton and musculature for a region of the body. I wanted to focus my project on the anteater’s feeding habits so the pose I drew was of the anteater digging so that I could show the musculature of the arm. I also created a composite of the head, showing the musculature of the tongue and mouth.

All three layers combines in photoshop.

Fleshed out anteater digging. I worked heavily from a plastic figurine since I couldn’t find many good reference pictures of the pose.

The anteater’s full skeleton. The back was painted with white and yellow ochre acrylic and the details were rendered on the front in graphite and colored pencil.

Musculature of the arms. Supposedly the giant anteater is capable of crushing jaguar in their arms, so I figured it would be the most action-packed region of the animal.

Super cool!

It  was dead week in the studio. The squirrel I had found just after being hit by a car, and the sardines are for an article I am illustrating.

The Haast’s Eagle
posted by Blueeyedeagle on Carnivora Forum
Body Length: 140 cm / 4 ft 7 in. Height: 90 cm / 2 ft 11 in. Wingspan 2.6-3 m / 8 ft 6 in - 9 ft 10 in. Weight: 10-15 kg / 22-33 lb.
(text from wikipedia)
Haast’s Eagles were the largest true raptors, outsizing even the largest living vultures. This wingspan was similar to that of some surviving eagles (the largest Golden Eagles and Steller’s Sea Eagles), though even the largest extant eagles are about 40% smaller in body size. Short wings may have aided Haast’s Eagle when hunting in the dense scrubland and forests of New Zealand. Haast’s Eagle is sometimes portrayed as having evolved towards flightlessness, but this is not so; rather, it represents a departure from its ancestors’ mode of soaring flight toward higher wing loading and increased maneuverability. The strong legs and massive flight muscles would have enabled the birds to take off with a jumping start from the ground, despite their great weight. The tail was almost certainly long (up to 50 cm (20 inches), in female specimens) and very broad, further increasing maneuverability and compensating for the reduction in wing area by providing additional lift. 
Haast’s Eagle preyed on large, flightless bird species that were unable to defend themselves from the striking force and speed of these eagles. Among its prey was the moa which was up to 15 times its weight. It attacked at speeds up to 80 km/h (50 mph), often seizing its prey’s pelvis with the talons of one foot and killing with a blow to the head or neck with the other. Its size and weight indicate a bodily striking force equivalent to a cinder block landing on the target from a height of 25 m (82 ft). Its large beak also could be used to rip into the internal organs of its prey and death then, would have been caused by blood loss.
