Lampsilis bracteata, also known as the Texas fatmucket, [2] is a species of freshwater mussel in the family Unionidae, the river mussels. [ 1 ] [ 2 ] [ 3 ] This species is endemic to the tributaries of the Colorado River within the Edwards Plateau region in Texas , the United States.
Most barnacles are encrusters, attaching themselves to a hard substrate such as a rock, the shell of a mollusc, or a ship; or to an animal such as a whale (whale barnacles). The most common form, acorn barnacles, are sessile, growing their shells directly onto the substrate, whereas goose barnacles attach themselves by means of a stalk. [8]
After about three months in the nursery, mussel seed is "socked" (placed in a tube-like mesh material) and hung on longlines or rafts for grow-out. Within a few days, the mussels migrate to the outside of the sock for better access food sources in the water column. Mussels grow quickly and are usually ready for harvest in less than two years.
Six species of freshwater mussels native to the Central Texas region will be listed as endangered species as of July 4, the U.S. Fish and Wildlife Service announced Monday.

Creepy, barnacle-encrusted dolls seem to favor a particular stretch of Texas beach and have been surfing their way shoreward to a 40-mile swath of sand on the Gulf of Mexico since early last year.
While many barnacles deal with competition for space by organisms such as limpets and mussels by growing many organisms close together in colonies, Megabalanus responds by rapidly growing to a very large size. [4] Their large size also helps reduce predation, although it makes them large enough to be harvested for human consumption.
Rhizocephala are derived barnacles that are parasitic castrators. Their hosts are mostly decapod crustaceans, but include Peracarida, mantis shrimps and thoracican barnacles. Their habitats range from the deep ocean to freshwater. [1] [2] Together with their sister groups Thoracica and Acrothoracica, they make up the subclass Cirripedia. [3]
