Vaname shrimp (Litopenaeus vannamei) is an export commodity from the fisheries sub-sector which has high economic value. The development of aquaculture systems traditional to intensive potential for disease attacks. Control spread must be done as early possible, one method prevention using immunostimulants. An alternative source immunostimulants that can used increase immune system octopus (Oct...

Methods The research was carried out in 86 patients treated in the Outpatients Clinic of Allergic Diseases. Every patient was interviewed for allergy history and family history of diseases. Every patient had: 1. Prick by prick (PbP) for seafood allergens (squid Illex argentinus and “Black tiger” shrimps Penaeus monodon, octopus Octopus vulgaris, moules Mytilus edulis ). 2. Skin prick test (SPT)...

Cellular mechanisms underlying learning and memory were investigated in the octopus using a brain slice preparation of the vertical lobe, an area of the octopus brain involved in learning and memory. Field potential recordings revealed long-term potentiation (LTP) of glutamatergic synaptic field potentials similar to that in vertebrates. These findings suggest that convergent evolution has led ...

1. Optic glands transplanted from one Octopus vulgaris into another cause enlargement of the gonads and ducts of the recipient. 2. Enlargement occurs whether or not the gland was secreting when implanted and regardless of the sex of the donor or recipient. 3. Glands derived from Eledone moschata or Octopus macropus implanted into O. vulgaris are as effective as glands derived from O. vulgaris. ...

In vertebrate visual pigments, a glutamic acid serves as a negative counterion to the positively charged chromophore, a protonated Schiff base of retinal. When photoisomerization leads to the Schiff base deprotonating, the anionic glutamic acid becomes protonated, forming a neutral species that activates the visual cascade. We show that in octopus rhodopsin, the glutamic acid has no anionic cou...

This study highlights for the first time individual differences in ethology and vulnerability of Octopus vulgaris (i.e. body postures, movements skin displays) facing passive baited traps. Common octopus exposed to a trap during three consecutive first-capture tests exhibited diverse behavioural pattern sequences resembling when searches hunts its wild prey. Overall, they visually recognized ne...

Soft Robotics In article number 2300088 by Mattia Gazzola and co-workers, an octopus-inspired control framework coordinates multiple soft arms through a hierarchical approach, where reinforcement learning takes high-level decisions, fast energy shaping controls low-level motor execution, reflexive behavior accomodates for environmental disturbances. So equipped, this octopus succeeds in increas...

Transferring skills from a biological organism to a hyper-redundant system is a challenging task, especially when the two agents have very different structure/embodiment and evolve in different environments. In this article, we propose to address this problem by designing motion primitives in the form of probabilistic dynamical systems. We take inspiration from invertebrate systems in nature to...

S-Crystallin is a major protein present in the lenses of cephalopods (octopus and squid). To facilitate the cloning of this crystallin gene, cDNA was constructed from the poly(A)+ mRNA of octopus lenses, and amplified by PCR for nucleotide sequencing. Sequencing of 10 of 15 positive clones coding for this crystallin revealed three distinct S-crystallin isoforms with 61-64% identity in nucleotid...
