The host needed for each mussel species is typically a fish, and sometimes only a very specific fish species will work. Many mussel species have complex adaptations that attract their hosts, from…

For freshwater mussels, specifically those occurring in Texas, distribution information is available, but only at a broad scale, and much of it is based on shell material rather…
