Vision in Horseshoe Crabs
Limulus has been a superb animal model for understanding vision in higher animals, including man. Nobel-prize winning research on the lateral eye of Limulus by H. K. Hartline revealed fundamental principles of retinal function applicable to all eyes. The function of the Limulus lateral eye is now well understood as is its essential role in the animal’s mating behavior.
متن کاملZoothamnium duplicatum infestation of cultured horseshoe crabs (Limulus polyphemus).
An outbreak of the sessile peritrich Zoothamnium duplicatum in a pilot, commercial-scale Limulus polyphemus hatchery resulted in the loss of ∼96% (40,000) second/third instar larvae over a 61day period. peritrich growth was heavy, leading to mechanical obstruction of the gills and physical damage. The peritrichs were controlled without resultant loss of juvenile crabs by administering 10ppm chl...
متن کاملCircadian rhythms in locomotor activity of juvenile horseshoe crabs.
The American horseshoe crab, Limulus polyphemus, is a classic model for vision research. Not only are the lateral eyes of Limulus relatively simple, but they share many processes with the eyes of more advanced animals, including humans (1). The eyes of Limulus also exhibit a remarkable circadian rhythm: they become nearly 1,000,000-fold more sensitive at night, accommodating for the roughly 1,0...
متن کاملPaternity in horseshoe crabs when spawning in multiple-male groups.
Unpaired or satellite male horseshoe crabs, Limulus polyphemus, are attracted to and often form a group around a pair (a female with an attached male) that is nesting in the high intertidal zone. These males are engaged in sperm competition. We observed nesting pairs and their associated satellites in the wild, collected and reared their eggs and used genetic markers to examine paternity. We fo...
متن کاملEffects of blood extraction on horseshoe crabs (Limulus polyphemus)
E-mail address (for J. Berkson, contact author): [email protected] the United States, mandated that all biomedical companies actively bleed ing horseshoe crabs estimate mortal ity rates resulting from their bleeding process (Schrading et al.3). Because of the unique methods of the different biomedical companies, each company was required to quantify its own rate of mortality. BioWhittaker, a CA...
