Pisidia longicornis, the long-clawed porcelain crab, is a species of porcelain crab that lives in the north-eastern Atlantic Ocean. It varies from reddish to white, and grows to a carapace width of 1 cm (0.4 in). It was first named by Carl Linnaeus in 1767, although the etymology remains unclear.
The longhorn crazy ant, also known as "black crazy ant", is a species of small dark-coloured insect in the family Formicidae. These ants are commonly called "crazy ants" because instead of following straight lines, they dash around erratically. They have a broad distribution, including much of the tropics and subtropics and are also found in buildings in more temperate regions, making them one of the most widespread ant species in the world. This species, as well as all others in the ant subfamily Formicinae, cannot sting.
Copelatus longicornis is a species of diving beetle. It is part of the genus Copelatus of the subfamily Copelatinae and the family Dytiscidae. It was described by Sharp in 1882.
Myja longicornis is a species of sea slug, an aeolid nudibranch, a marine gastropod mollusc in the family Tergipedidae. It was thought to be a close relative of Tergipes but molecular phylogeny reveals it to be a paedomorphic facelinid.
