Biology

The goby and shrimp share the same extensive burrow which the shrimp excavates in sandy or silty areas of the seabed. It has one or more openings, the positions of which are constantly changing as the shrimp engages in burrowing activities. During the day the goby rests on the burrow floor with its head by the opening or may emerge further. It feeds by picking small invertebrates out of the substrate that has been disturbed by the shrimp or by taking mouthfuls of sediment and extracting edible organisms and detritus. 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. At night both retreat into the interior of the burrow and the entrances are sealed.

The goby probably lays its eggs in a mass in the burrow as happens with other members of this genus. The shrimp lives singly in the burrow and at breeding time probably make an opening close to an adjoining burrow occupied by a shrimp of the opposite sex. The female shrimp carries her eggs under her abdomen.

Famous quotes containing the word biology:

    The “control of nature” is a phrase conceived in arrogance, born of the Neanderthal age of biology and the convenience of man.
    Rachel Carson (1907–1964)

    Nothing can be more incorrect than the assumption one sometimes meets with, that physics has one method, chemistry another, and biology a third.
    Thomas Henry Huxley (1825–95)
