TEMPERATURE EFFECTS ON THE DEVELOPMENTAL RATE OF SQUID (LOLIGO PEALEI) EMBRYOS

The Significance of the Bohr Effect in the Respiration and Asphyxiation of the Squid, Loligo Pealei

Contact with Squid Egg Capsules Increases Agonistic Behavior in Male Squid (Loligo pealei).

Agonistic (aggressive) behavior is costly (I). For this reason. males should tight only when it will increase their reproductive fitness. In some species, the last male to mate with a female before she oviposits sires most of the offspring (2). If Loligo pealei has a similar system of sperm precedence. a male should drive away nearby males when females are about to lay their eggs. In L. pealei....

A kinematic analysis of tentacle extension in the squid Loligo pealei

High-speed cine recordings of prey capture by the squid Loligo pealei were used to analyze the kinematics of the rapid tentacular strike. The proximal portion of the tentacle, the stalk, elongates during the strike. The non-extensible distal portion of the tentacle, the club, contacts the prey and attaches using suckers. Seven sequences of prey capture filmed at 750 frames s-1 were analyzed fra...

The homeodomain transcription factor Phox2 in the stellate ganglion of the squid Loligo pealei

Homeodomain transcription factors regulate development of embryos and cellular physiology in adult systems. Paired-type homeodomain genes constitute a subclass that has been particularly implicated in establishment of neuronal identity in the mammalian nervous system. We isolated fragments of eight homeodomain genes of this subclass expressed in the stellate ganglion of the North Atlantic long ...
