As you'd expect, their analysis found that the spinier the male genital, the stronger the female's. Dang.

It shares its range with the larger and much spinier Euastacus sulcatus which tends to be present in the larger creeks while E. dalagarbe occupies the smaller ones, many of which dry up in summer.

Artocarpus camansi can be distinguished from the closely related Artocarpus altilis by having spinier fruits with numerous seeds. Artocarpus mariannensis can be distinguished by having dark green elongated fruits with darker yellow flesh, as well as entire or shallowly lobed leaves.

Hakea auriculata is a lignotuberous compact upright shrub growing to high. Smaller branches are either covered in long soft hairs or smooth. The hairless leaves are egg-shaped wider toward the apex long and wide. Leaves are toothed spaced apart, 1-7 teeth each side, narrower and spinier toward the tip.

Males grow to about and females to about in snout–vent length. The dorsum is metallic green, mottled with darker drab green or brown blotches and covered by large, spinous bumps (females are spinier than males). Also the limbs are spiny. The ventrum is white and has some scattered black blotches or smaller spots.

It is found in France, the Iberian Peninsula and the Maghreb and grows to a larger size and has a spinier skin than its more northern counterparts with which it intergrades. It is now accepted as Bufo spinosus. The Gredos toad, B. b. gredosicola, is restricted to the Sierra de Gredos, a mountain range in central Spain.

George R. Proctor, in Acevedo-Rodríguez & Strong (2005), pp. 138–139 In Dominica, palm systematist Scott Zona and colleagues documented the presence of two distinct populations of Aiphanes palms on the island—one which was larger and spinier, and the other that was smaller, more slender, and less spiny. This led them to speculate that this may represent a second species of Aiphanes.

It is an annual plant growing to 60 cm tall, with leathery, hairy leaves up to 30 cm long and 8 cm broad, with small spines on the margins. The flowers are yellow, produced in a dense flowerhead (capitulum) 3–4 cm diameter, surrounded by numerous spiny basal bracts. The related genus Notobasis is included in Cnicus by some botanists; it differs in slender, much spinier leaves, and purple flowers.

It is noticeably similar in appearance to its relative of the same genus, the jackfruit (Artocarpus heterophyllus). Breadfruit has hundreds of varieties and thousands of common names varying according to its geographic distribution, and is cultivated in some 90 countries. The closely related Artocarpus camansi can be distinguished from A. altilis by having spinier fruits with numerous seeds. Artocarpus mariannensis can be distinguished by having dark green elongated fruits with darker yellow flesh, as well as entire or shallowly lobed leaves.

Hosmer's spiny-tailed skink is mostly reddish-brown on top, with both scattered darker and paler spots along the back, legs, and tail. It has a darker brown head and neck, white abdomen, and a few dark brown blotches under the chin. The snout–vent length (SVL) is 180mm, with a round, tapering tail about 60% of the SVL. It is most closely related to Cunningham's spiny-tailed skink (Egernia cunninghami), however the tail of E. hosmeri is flattened and spinier than that of E. cunninghami.

A cardon specimen is the tallest living cactus in the world, with a maximum recorded height of , with a stout trunk up to in diameter bearing several erect branches. In overall appearance, it resembles the related saguaro (Carnegiea gigantea), but differs in being more heavily branched and having branching nearer the base of the stem, fewer ribs on the stems, blossoms located lower along the stem, differences in areoles and spination, and spinier fruit. Its flowers are white, large, nocturnal, and appear along the ribs as opposed to only apices of the stems.

The species was first described by Christian Hendrik Persoon in 1797. It was later reduced to a variety of Lycoperdon gemmatum (as L. gemmatum var. echinatum; L. gemmatum is now known as Lycoperdon perlatum) by Elias Magnus Fries, but American mycologist Charles Horton Peck, who extensively studied the North American distribution of the genus, raised it again to species level in 1879. He thought it worthy of status as a species distinct from L. gemmatum because of the different character of its warts, its much spinier appearance, and the smoother surface of the peridium underneath the spines.
