Some snapping shrimp species share burrows with goby fish in a mutualistic symbiotic relationship. The burrow is built and tended by the pistol shrimp, and the goby provides protection by watching out for danger. When both are out of the burrow, the shrimp maintains contact with the goby using its antennae.
The tiger pistol shrimp lives in burrows in symbiosis with certain goby species such as Cryptocentrus cinctus, Amblyeleotris guttata or Stonogobiops yasha. The shrimp digs and maintains the burrows which are the dens for both animals, while the goby acts as a watchman, warning of danger the shrimp cannot see due to poor eyesight. [8]
The shrimp is mainly a detritus feeder. The shrimp has poor sight and is alert to the actions of the goby. The shrimp is more vulnerable to predation and is quick to retreat to safety even when the danger level is low. If the fish swims into the burrow head first to escape more immediate danger, the shrimp darts in immediately.
The bigclaw snapping shrimp feeds on worms, small crustaceans and fish such as gobies and pearlfish. It is itself eaten by the weakfish (Cynoscion regalis). It is often associated with the black-clawed mud crab (Panopeus herbstii), sharing the crab's burrow and remaining uneaten, even though this crab eats similar-sized shrimps of other species ...
Amblyeleotris is a genus of fish in the family Gobiidae found throughout the Indo-Pacific region. This is the largest genus of the shrimp gobies or prawn gobies, so-called because of their symbiotic relationship with certain alpheid shrimps.
Excellent general information on this goby, and the genus Stonogobiops in general, along with their mutualism with pistol shrimp - An interesting study analysing daily shrimp activity cycles, the effects of goby presence on shrimp behavior, and the effects of predation on numerical density and size of gobies
An example of this is the mutualistic symbiotic relationship between the goby, a small bottom-dwelling fish, and an alpheid, or snapping, shrimp. The goby usually sits at the entrance of a burrow that the shrimp digs and maintains. While the shrimp works on the burrow, the goby would stand watch.
Mutualism refers to relationship where one or both partners provide a service or resources to the other. [13] Caribbean cleaning gobies engage in mutualism by removing and feeding on ectoparasites on their clients. They present themselves and wait for clients at cleaning stations, as they largely depend on cleaning for their food. [14]
