swimmeret การใช้

• Male and female specimens can be distinguished by examining the swimmerets.
• The appendices are called pleopods or swimmerets, and can be used for more purposes than just swimming.
• Underneath the thorax behind the walking legs are paired pleopods ( swimmerets ) used for swimming and brooding eggs.
• On the endopodite of the second swimmeret of the male is a clamp-like feature called the appendix masculina.
• In this stage, the pleopods ( swimmerets; abdominal appendages ) become functional, and the animal closely resembles the adult form.
• Krill normally swim at a pace of 5 10 cm / s ( 2 3 body lengths per second ), using their swimmerets for propulsion.
• Unlike crabs and lobsters, shrimp have well developed pleopods ( swimmerets ) and slender walking legs; they are more adapted for swimming than walking.
• They swim forward by paddling with swimmerets on the underside of their abdomens, although their escape response is typically repeated flicks with the tail driving them backwards very quickly.
• The first has mixed sensory and motor nerves innervating swimmerets while the second has sensory and motor neurons that innervate the extensor muscles, while the third root contains only motor neuron projections that extend into the flexor muscles.
• "' Pleopods "'( also called " swimmerets " ) are primarily swimming legs, and are also used for brooding the eggs ( except in prawns ), catching food ( then swept to the mouth ), and can sometimes bear their own gills.
