Cliff Case-bearer

The Cliff Case-bearer, Coleophora species, is a small micro-moth in the family Coleophoridae whose larvae construct and carry portable, protective cases made from plant material, silk, and their own excrement, hence the name case-bearer. The larvae feed within these cases on the leaves or seeds of specific host plants, often grasses or forbs growing on cliff faces, rocky slopes, and coastal headlands. The Coleophoridae is a very large family of small moths with thousands of described species, many of them host-plant specific. Adult Cliff Case-bearers are typically narrow-winged, with lanceolate, often buff or gray-brown wings held tightly against the body at rest. Identification to species level requires microscopic examination of genitalia. The larvae overwinter in their cases on the ground before resuming feeding in spring. The ecology of cliff case-bearers is closely tied to their specific host plants, and they are sensitive to changes in vegetation management and plant community composition on cliffs and rocky habitats. As with many microlepidoptera, specific information on distribution, host plant associations, and conservation status requires detailed taxonomic study of the exact species in question.

Clymene Dolphin

The Clymene dolphin, Stenella clymene, is a small cetacean endemic to the tropical and subtropical waters of the Atlantic Ocean, ranging from the Gulf of Mexico and Caribbean Sea south along both the western and eastern Atlantic margins to approximately 20 degrees south latitude. Often called the short-snouted spinner dolphin, it is the only known naturally occurring cetacean hybrid species, believed to have originated through hybridization between the spinner dolphin (S. longirostris) and the striped dolphin (S. coeruleoalba). Clymene dolphins are acrobatic and frequently perform spinning leaps similar to but less elaborate than their spinner relatives. They travel in schools typically ranging from 10 to several hundred individuals, sometimes associating with other dolphin species. The species inhabits deep offshore pelagic waters and is rarely observed close to coastlines. It feeds primarily on fish and cephalopods, foraging at night when mesopelagic prey move into shallower waters. Clymene dolphins measure approximately 1.7–2 meters in length and display a distinctive tripartite pattern of dark cape, lighter grey flanks, and white or pale yellow belly. The species is assessed as Least Concern by the IUCN due to its relatively wide range and no evidence of major population-level threats.
