Range

Distributed across Belgium, Denmark, Norway, Sweden, and United States.

Common Seahorse

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 7 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Australia, India, Indonesia, Japan, and Philippines. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Drill

<em>Dichrorampha petiverella</em>, the common drill, is a moth in the family Tortricidae. This species is distributed across Belgium, Denmark, Norway, Sweden, and the United States, typically inhabiting terrestrial and freshwater environments including meadows, grasslands, and woodland margins. The common drill is a small, cryptically patterned tortricid moth, often with brownish or grayish wing markings that provide camouflage against bark and plant surfaces. Adults are generally nocturnal and are often attracted to light. Larvae of <em>Dichrorampha petiverella</em> are typically root-boring, feeding internally within the roots of herbaceous plants, particularly members of the family Asteraceae. This feeding habit can occasionally cause economic damage to cultivated plants but is generally considered minor in natural ecosystems. The species is assessed as Least Concern, reflecting stable populations across its range. Biological traits of this moth beyond those documented here remain relatively poorly detailed in the broader scientific literature.

Common Seahorse

The common seahorse is found in tropical and temperate waters. Males carry and deliver the babies.
