Title: An extraordinary reproductive strategy in freshwater bivalves: prey mimicry to facilitate larval dispersal

Author: Haag, Wendell; Butler, Robert S.; Hartfield, Paul D.

Date: 1995

Source: Freshwater Biology (1995) 34, 471-476

Publication Series: Miscellaneous Publication

Description: 1. Females of the North American freshwater bivalve Lampsilis provalis release their larvae, which are obligate parasites on fish, in a discrete mass (superconglutinate) resembling a small fish in shape and coloration. After release, the mass remains tethered to the female by a long, transparent, mucous strand and, in stream currents, displays a darting motion that further mimics a small fish.

2. Release of superconglutinates was observed in March and April at water temperatures of 14-17°C. However, superconglutinates detached from the parent mussel were observed from March to June at water temperatures of 11-26°C, indicating that release may occur into the summer.

3. The superconglutinate lure may function to attract a predaceous fish to ingest the mass, ensuring that the larvae are exposed to a suitable host.

4. This reproductive strategy was confirmed recently to occur in a congener, L. subangulata and is suspected to occur in another congener, L. australis.
