Octopus tetricus (Mollusca: Cephalopoda) as an ecosystem engineer ; Octopus tetricus (Mollusca: Cephalopoda) como ingeniero de ecosistemas
The Sydney octopus (Octopus tetricus) occurs in unusual numbers on a shell bed of its prey remains that have accumulated as an extended midden where additional octopuses excavate dens. Here, O tetricus are ecosystem engineers, organisms that modulate availability of resources to other species and to their own species by causing physical state changes in materials. A community of invertebrate gr...
متن کاملPrey-handling behaviour of Octopus vulgaris (Mollusca, Cephalopoda) on Bivalve preys.
This study examines the ability of Octopus vulgaris to prey on bivalve molluscs showing that octopuses exhibited the same behavioural pattern irrespective of the prey species. When the initial pulling method did not result efficient octopuses skipped to drilling accompanied by an increase in the handling time. A complete behavioural repertoire of O. vulgaris in handling bivalve preys is also gi...
متن کاملEndogenous and exogenous control of gametogenesis and spawning in echinoderms.
Most echinoderms display seasonal or other temporal cycles of reproduction that presumably result from the complex interplay of endogenous and exogenous signals. Various environmental, chemical and hormonal factors, acting directly or indirectly, individually or in combination, have been proposed to cue, favour or modulate a suite of reproductive functions from the onset of gametogenesis to gam...
متن کاملObservations on feeding and biochemical characteristics to improve larviculture of Robsonella fontaniana (Cephalopoda: Octopodidae)
At present, the production of merobenthic octopuses with a post-eclosion planktonic phase is a great challenge for global aquaculture. So far, juveniles from only four species have been reported to have been obtained under controlled rearing conditions: Octopus vulgaris, Octopus joubini, Enteroctopus dofleini and Robsonella fontaniana, the only Chilean species. Robsonella fontaniana (Orbigny, 1...
متن کاملGenome‐wide comparisons reveal a clinal species pattern within a holobenthic octopod—the Australian Southern blue‐ringed octopus, Hapalochlaena maculosa (Cephalopoda: Octopodidae)
The southern blue-ringed octopus, Hapalochlaena maculosa (Hoyle, 1883) lacks a planktonic dispersal phase, yet ranges across Australia's southern coastline. This species' brief and holobenthic life history suggests gene flow might be limited, leaving distant populations prone to strong genetic divergence. This study used 17,523 genome-wide SNP loci to investigate genetic structuring and local a...
