Exosphaeroma pentcheffi is a species of marine isopod of the family Sphaeromatidae.
This species lacks strong sexual dimorphism, with both sexes possessing prominent dorsal tubercles. The largest male specimen measured 6.8 mm, while the largest female measured 4.6 mm. [1]
This species is known to inhabit the intertidal zone of the Palos Verdes Peninsula, Los Angeles, California. [1]
E. pentcheffi is named for Natural History Museum of Los Angeles County researcher N. Dean Pentcheff. Pentcheff led the field trip for an invertebrate zoology lab course at Loyola Marymount University during which the species was discovered. [1]
California is a state in the Western United States. It is bordered by Nevada to the east, Arizona to the southeast, the Pacific Ocean to the west, Oregon to the north, and the Mexican state of Baja California to the south.

Sphaeromatidae is a family of isopods, often encountered on rocky shores and in shelf waters in temperate zones. The family includes almost 100 genera and 619 known marine species. Within these genera, there are groups that share distinctive morphologies; further research may reclassify these genus-groups as separate families.

Exosphaeroma is a genus of marine isopod of the family Sphaeromatidae. This genus is found in shallow ocean waters worldwide. It is notable for being one of the few genera of sphaeromatid to be found in the southern reaches of the Southern Ocean. The greatest diversity of Exosphaeroma occurs in the Southern Hemisphere.
Exosphaeroma amplicauda is a species of marine isopod of the family Sphaeromatidae.
