  • Pachygrapsus

    shore crabs, lined shore crabs

    Pachygrapsus is a genus of small shore crabs in the family Grapsidae. The genus comprises approximately 14 species distributed across coastal regions, with Pachygrapsus crassipes (lined shore crab) being among the best-studied members. Recent genetic data suggest the genus may be polyphyletic, indicating potential taxonomic revision. Species in this genus occupy intertidal habitats and exhibit complex behavioral adaptations for life in dynamic coastal environments.

  • Trogoderma grassmani

    Trogoderma grassmani is a species of dermestid beetle in the genus Trogoderma, described by Beal in 1954. Like other members of its genus, it belongs to a group of beetles commonly known as cabinet beetles or warehouse beetles, many of which are significant pests of stored products. The species is native to North America. Information specific to this species is limited compared to better-known congeners such as Trogoderma granarium (khapra beetle) and Trogoderma variabile (warehouse beetle).
