Narrator: And, along with their long, hooklike fingernails, allow them to hang easily.

But other experts believe Lucy's hooklike hands and her flexible shoulders suggest she was a decent tree-climber.

She goes to New Caledonia, an island between Australia and Fiji, where "free from the burden of vigilance" — against predators — a race of crows can futz and experiment with the materials around them until they've fashioned all kinds of hooklike, food-procuring tools.

There is a hooklike pattern on the forewings, with black proximal and paler (almost white) distal margins. The hindwings are pale brown. Adults have been recorded in June and July.

They spin together two or three leaves, and mine them out. The mine is full depth and hooklike. It starts as a narrow gallery, but quickly widens into a blotch. Pupation takes place outside of the mine.

Ornithocheirid shinbones (or tibiae) are similarly developed and of equal length to the femora. Although the feet in ornithocheirids are poorly known, they seem to be relatively small and gracile, with undeveloped claws and a hooklike fifth metatarsal.

The fruit is rounded, 15 to 20 centimeters wide, and covered with a felt-textured brown skin that is hard to cut open when ripe. The surface of the fruit has hooklike projections.

Kaben, Ocean Side Kaben is a small island, no more than 2.5 kilometers long and a kilometer across. The island has around in area. It is almost rectangularly-shaped, with a slight hooklike protuberance on the northeastern region of the island. Kaben is lightly inhabited, having had a few man-made structures erected along its southeast coast.

Studies of tooth wear suggest they ate leaves, twigs, fruit, and bark. Chalicotheriines, such as Anisodon, lived only in moist, closed-canopy forests, never reached the Americas, and developed very unusual anatomy for an ungulate. Their shorter necks and horse- like heads did not show adaptations to reach high. Instead, they developed very long forelimbs with mobile shoulder joints and hooklike claws.

The leaves are narrow, curving, and hooklike, hardening into sharp spines up to 2.5 centimeters long. The inflorescence bears one or two flower heads which are each enveloped in four to six woolly phyllaries. Each head contains up to 8 tubular yellow flowers up to a centimeter long. The fruit is a densely hairy achene which may be nearly 2 centimeters long, including its pappus of long bristles.

The pale-throated sloth can hang so securely with its hooklike claws that it even falls asleep in this position. It may even stay suspended in the trees for some time after it dies. They have been reported to spend over eighteen hours each day asleep, and move through the tree canopy only very slowly. They periodically descend from the trees to defecate, depositing a pile of small pellets in a hole dug into the ground.

The small (3–5 mm in length), disk-shaped fossil has seven hook-like isomers in a star-like arrangement in the clearly expressed peripheral undivided zone. T. hamulifera is probably a member of Proarticulata, as it is strongly similar to Praecambridium sigillum in the general shape, and the presence of hooklike isomers; Tamga is also similar to Onega stepanovi in the flattened body with a compact group of ledges-isomers in the central part encircled by an undivided zone. The fossils of Tamga could possibly be sclerites, for example, as sclerites of palaeoscolecids show a similar shape, a disk with a ring or rows of tubercles in the center. But the size of Tamga's fossils is two orders of magnitude smaller than those of palaeoscolecid sclerites, and no mineralized sclerites of any sort have ever been found or diagnosed in the Vendian–Ediacaran communities.
