WebJul 10, 2024 · Copepod movements were classified as sinking, swimming, twitching of the first antennae or urosome, hopping or jumping. The copepod was classified as sinking when it was motionless. Swimming was defined as rhythmic beating of the feeding appendages (cephalic appendages). During swimming, the copepods sometimes … Webrequired for an object to jump out of water against gravity and surface tension. First, we designed and performed physical experiments of shooting spherical particles towards the liquid surface to mimic planktonic copepods jumping as described in §2. In §3.1, we have developed a simple theor-
WebFeb 1, 2011 · Pelagic copepods jump to relocate, to attack prey and to escape predators. However, there is a price to be paid for these jumps in terms of their energy costs and the hydrodynamic signals they generate to rheotactic predators. Using observed kinematics of various types of jumps, we computed the impo … WebApr 18, 2016 · Planktonic copepods are small crustaceans that have the ability to swim by quick powerful jumps. Such an aptness is used to escape from high shear regions, which may be caused either by flow perturbations, produced by a large predator (i.e., fish larvae), or by the inherent highly turbulent dynamics of the ocean. Through a combined …
WebDec 17, 2010 · Thus, the copepod can initiate its attack jump when the prey is in an optimal position for attack (Jiang and Paffenhöfer, 2008), and precisely orient its attack strike, even when this requires a complete turn and rotation of the body during the strike (Kiørboe et al., 2009).
