Coahuila-Texas Yucca

Yucca coahuilensis, the Coahuila-Texas yucca, is a striking succulent plant in the family Asparagaceae native to the Chihuahuan Desert along the border region of Coahuila state in northeastern Mexico and adjacent southwestern Texas. The species occupies arid to semi-arid shrubland, desert grassland, and limestone hillsides where it grows on rocky, well-drained soils in areas receiving low and highly seasonal rainfall. Like all yuccas, Y. coahuilensis produces a rosette of stiff, sword-like leaves with sharp terminal spines and a tall flowering stalk bearing large, bell-shaped white flowers that are pollinated almost exclusively by yucca moths in the genus Tegeticula, with which the plant maintains an obligate mutualistic relationship. The moth larvae feed on developing seeds while simultaneously pollinating the flowers, a system representing one of the most tightly co-evolved plant-pollinator mutualisms in North America. Yucca coahuilensis is classified as Vulnerable by the IUCN, reflecting its restricted range in a binational border region subject to habitat alteration from ranching, agricultural expansion, and changing precipitation patterns associated with climate change in the Chihuahuan Desert ecosystem.

Epaulard

The largest member of the dolphin family, orcas reach up to 9 meters and 6 tonnes and are found in every ocean from Arctic to Antarctic. Apex predators living in matrilineal pods with distinct dialects, hunting strategies, and cultural traditions that differ between populations. Some populations specialize in fish, others in marine mammals. No natural predators; orcas sit at the top of every marine food chain they inhabit.
