American black bears can be distinguished from brown bears by their smaller size, their less concave skull profiles, their shorter claws and the lack of a shoulder hump.
Some specimens may develop a white "crescent moon" mark on the chest. This white mark, which is constant in Asian black bears, occurs in only 25% of American black bears.[15]

On slightly yellow paper using black ink, there is Kotick the white seal with his arms protruding straight up out of the water. He is facing a sea cow who is darkly shaded, has large nostrils, small eyes, stocky body, and covered in seaweed. Behind Kotick is another sea cow who is eating seaweed, and in the background there are many other sea cows. One of the sea cows is sticking its tail out of the water, which resembles that of a dolphin. The coastline is visible to the right.

Various red fox colour mutations
White morph red foxes may be distinguished from Arctic foxes by their 25% greater size, longer muzzles, and longer, pointed ears.[25] This captive example shows the dark pigment of the eyes, nose, and lips that would not occur in an albino. Complete albinism in red foxes is rare and primarily occurs in southern forest zones. Typically, albinism is accompanied by deformations and usually develops in years of insufficient food.[26]

Lymnaea stagnalis in typical mating position of this species. The top snail is performing the male role (sperm donor), its white preputium (penis-carrying organ, Pp) can be seen inserted under the shell of the sperm recipient, where the female opening is located. During insemination, sperm (from the seminal vesicles) and seminal fluids (from the prostate gland) are transferred. Since these are simultaneous hermaphrodites, sexual roles can be swapped immediately afterwards.[29]

Evolutionary tree chart emphasizing the subfamily Homininae and the tribe Hominini. After diverging from the line to Ponginae the early Homininae split into the tribes Hominini and Gorillini. The early Hominini split further, separating the line to Homo from the lineage of Pan. Currently, tribe Hominini designates the subtribes Hominina, containing genus Homo; Panina, genus Pan; and Australopithecina, with several extinct genera—the subtribes are not labelled on this chart.
A model of the evolution of the genus Homo over the last 2 million years (vertical axis). The rapid "Out of Africa" expansion of H. sapiens is indicated at the top of the diagram, with admixture indicated with Neanderthals, Denisovans, and unspecified archaic African hominins.[46]

An illustration of a shark head (sideview). Visible are wrinkles and an exaggerated nose and eyes, and at the bottom are two individual drawings of shark teeth
The depiction of a shark's head by Nicolas Steno in his work The Head of a Shark Dissected
A black megalodon tooth and two white great white shark teeth above a centimeter scale, the megalodon tooth extends between the zero and thirteen-and-a-half centimeter marks. One great white tooth extends between the eleven and thirteen centimeter marks, and the other extends between from the thirteen and sixteen centimeter marks.
Megalodon tooth with two great white shark teeth
A drawing of a swimming shark showing the front left underside view
Restoration of megalodon with a similar appearance to the great white shark
An illustration of the side-view of a basking shark. The tail fin is crescent shaped with a larger upper lobe. The second-dorsal-fin and anal fins are small, and a caudal keel starts directly above the anal fin. The dorsal fin is large and triangular with a blunt tip, and located near mid-length of the back. Five gill slits extend almost the full depth of the body, and the head has similar depth to the body. The mouth is partly open.
Megalodon may have had a build similar to the basking shark (Cetorhinus maximus).[48]: 35–36 
A sideview of the inside of a megalodon jaw reconstruction showing five rows of teeth. Each row is more horizontal than the last, with the last row essentially resting on the jaw.

An antique-looking illustration, numbered 321, showing a large, apparently left-handed, sea snail shell with knobs on the shoulders of the whorls
For a number of years during the 20th century, this very early illustration was designated as the neotype of this species: a figure of L. gigas from Recreatio mentis, et occuli (1684). The shell in the figure appears left-right reversed because of the engraving process. The original type was subsequently found, invalidating this designation.[81]
A queen conch shell is shown from five different perspectives
Five different views of an adult shell of L. gigas: abapertural (upper left), lateral (center), apertural (upper right), apical (lower left) and basal (lower right). Note: The lip of this shell has been filed down or cut down artificially, a common practice in the shell trade.

Skull seen from the side. Short-snouted as usual in mustelids, it has a pronounced sagittal crest, allowing for a very powerful bite in this species
Giant otters leave a pool together at the Philadelphia Zoo. The species is extremely social, a rarity among mustelids, and family groups are cohesive.
A giant otter den dug on a lake shore at Cantão State Park — the newly dug white sand is a sign of recent activity at this den.
Captive giant otters have contributed greatly to scientific knowledge of the species by providing readily available subjects for research on the species' reproduction and life cycle.
A captive giant otter, when feeding, grasps prey in its forepaws and begins eating immediately, at the head.

A Deinosuchus jaw fragment, exhibited at the North Carolina Museum of Natural Sciences: Fossils of this large alligatoroid have been discovered in 10 US states and northern Mexico.
Deinosuchus may have preyed upon large ornithopods. Kritosaurus lived alongside the giant crocodilian in the Aguja Formation ecosystem.[113]

The osteoderms of Deinosuchus, as illustrated by W.J. Holland. They are proportionately much thicker than those of modern crocodilians
Ebenezer Emmons illustrated two fossil teeth in 1858. Most likely, they belonged to the crocodilian that would later be named Deinosuchus.
This skull reconstruction, exhibited at the American Museum of Natural History for nearly a half-century, is probably the best known of all Deinosuchus fossils. The darker-shaded portions are actual fossil bone, while the light portions are plaster.

Lek mating arena, in which each male guards a territory of a few meters in size on average, and in which the dominant males may each attract up to eight females.[117] In addition, each individual is shown with variations in personal space (bubbles), whereby higher-ranking individuals have larger personal space bubbles.[118] Common bird leks typically have 25–30 individuals. A strict hierarchy accords the most desirable top-ranking males the most prestigious central territory, with ungraded and lesser aspirants ranged outside. Females come to these arenas to choose mates when the males' hierarchy has become established, and preferentially mate with the dominants in the centre.

Lek mating arena, in which each male guards a territory of a few meters in size on average, and in which the dominant males may each attract up to eight females.[127] In addition, each individual is shown with variations in personal space (bubbles), whereby higher-ranking individuals have larger personal space bubbles.[118] Common bird leks typically have 25–30 individuals. A strict hierarchy accords the most desirable top-ranking males the most prestigious central territory, with ungraded and lesser aspirants ranged outside. Females come to these arenas to choose mates when the males' hierarchy has become established, and preferentially mate with the dominants in the centre.

Retrieved 29 May 2012. {{cite web}}: Check |url= value (help) "the venerable line about scientists having proved that a bumblebee can't fly appears regularly in magazine and newspaper stories. It's also the kind of item that can come up in a cocktail party conversation when the subject turns to science or technology. [...] Often, the statement is made in a distinctly disparaging tone aimed at putting down those know-it-all scientists and engineers who are so smart yet can't manage to understand something that's apparent to everyone else. [...] the story has had remarkable staying power, and the myth persists that science says a bumblebee can't fly. Indeed, this myth has taken on a new life of its own as a piece of "urban folklore" on the Internet."
