Egg brooding behavior and embryonic development ofOctopus laqueus(Cephalopoda: Octopodidae)

Molluscan Research, 2006
Egg brooding behavior and embryonic development of the tropical intertidal octopus, Octopus laqueus, were observed in captivity. Three females spawned eggs in captivity and cared for them until the juveniles hatched. Some eggs were reared separately in an incubator for observation. The eggs of O. laqueus are small (mean capsule length 2.6 ± 0.1 mm) and

The Shallow-water Octopuses (Cephalopoda: Octopodidae) of the Philippines

Invertebrate Taxonomy, 1997
The shallow-water octopuses of the Philippines are diagnosed on the basis of material collected in a series of expeditions by the Smithsonian Institution to the region between 1978 and 1990. Twenty species of shallow-water octopuses are recognised, 18 in the genus Octopus, and one species each in the genera Hapalochlaena and Cistopus. Three new species

Distribution of Pareledone spp. (Octopodidae: Eledoninae) around South Georgia

2002
Small benthic octopodids of the genus Pareledone are commonly found around the shelf area of the sub-Antarctic island South Georgia but little is known about their biology. During three consecutive groundfish surveys in January–February 1994, September 1997 and January 2000, a total of 894 Pareledone spp. were caught in demersal trawl samples at depths

Double Hectocotylization in Hubb's Octopus, Octopus hubbsorum (Cephalopoda: Octopodidae)

Malacologia, 2019
Double hectocotylization in octopods has only been reported for some individuals of a few species, often affecting arms of the same pair. We herein report several cases of non-bilateral double hectocotylization in a single species collected in different locations of the Mexican Pacific coast. The octopuses were identified by morphological and molecular

A new intertidal octopus species, Octopus incella (Cephalopoda: Octopodidae), from Okinawa, southern Japan

Zootaxa, 2007
A new Octopus species, Octopus incella sp. nov., was found on a shallow coral beach on Okinawa Island, in the tropical waters of Japan. This species possesses the following characteristics: small size (28.2–31.0 mm mantle length [ML]), robust body with medium and approximately equivalent length (3.4–4.6 × ML) arms, relatively large normal suckers ...

The complete mitochondrial genome of Octopus conispadiceus (Sasaki, 1917) (Cephalopoda: Octopodidae)

Mitochondrial DNA Part A, 2014
In this paper, we determined the complete mitochondrial genome of Octopus conispadiceus (Cephalopoda: Octopodidae). The whole mitogenome of O. conispadiceus is 16,027 basepairs (bp) in length with a base composition of 41.4% A, 34.8% T, 16.1% C, 7.7% G and contains 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and a major non ...

Signs of multiple spawning in Graneledone pacifica (Cephalopoda: Octopodidae)

Journal of the Marine Biological Association of the United Kingdom, 2006
The examination of five females of the deep-benthic octopus Graneledone pacifica—a large-egged species: mature ovarian egg length >20 mm—showed that their developing oocyte size-distribution was normal in two specimens at an early maturation stage (largest oocyte length=3 mm), bimodal in two specimens at a more advanced stage (largest oocyte length ...
