A female Octopus macropus, the first ever observed spawning, attached eggs (4·0×1·2 mm, with a chorion stalk 4 mm in length) individually or in clusters to a hard substrate, and brooded them till hatching. Hatchlings measured 4·0 mm in dorsal mantle length, 5·5 mm in total length and were planktonic; their short arms had seven suckers each, the outer demi-branch of each gill had ten lamellae. The chromatophore pattern confirmed an earlier identification of young individuals from the plankton… 

Embryonic development in Octopus aegina Gray, 1849

Development stages of the embryo were sequenced based on morphological characters and the new born resembles adults in form except for its free-swimming mode of life.

Biology of the planktonic stages of benthic octopuses

Most of the understanding of octopus paralarvae comes from studies of just two species (Octopus vulgaris and Enteroctopus dofleini) and knowledge of the vast majority of benthic octopus species with planktonic stages is considered rudimentary or non-existent.

Development of Amphioctopus fangsiao (Mollusca: Cephalopoda) from eggs to hatchlings: indications for the embryonic developmental management

Results indicate that this species has several favorable characteristics for aquaculture, such as a short incubation period and a large body size of hatchlings, and also offers an important reference for the research of embryonic development in related species.

Two new records paralarva in the Eastern Mediterranean (Cephalopods: Mollusca)

Number of paralarval and early juvenile stage of cephalopod species recorded in the Levant basin and Aegean Sea is now 23, and two species are recorded for the first time from the Aegeans Sea and eastern Mediterranean Sea.

EMBRYONIC DEVELOPMENT OF AMPHIOCTOPUS MARGINATUS (TAKI) (MOLLUSCA: OCTOPODIDAE) IN CAPTIVITY

Octopuses, represented by over 300 species are the cephalopod molluscs inhabiting primarily tropical waters of the world. They are solitary invertebrates with little documentation of their response

Early Mode of Life and Hatchling Size in Cephalopod Molluscs: Influence on the Species Distributional Ranges

Hatchling size and associated developmental mode and dispersal potential seem to be main influential factors in determining the distributional range of cephalopods.

First record of paralarvae of Scaeurgus unicirrhus (Cephalopoda: Octopodidae)

The present first description of an advanced stage of Scaeurgus unicirrhus paralarvae is based on two specimens from the Adriatic Sea, and an identification key for Mediterranean early juvenile octopodids is proposed.

Developmental features of Octopus macropus Risso, 1826 (Mollusca, Cephalopoda)

La discussion replace les observations dans le contexte d'une difference, connue uniquement chez les Octopodidae, entre especes merobenthiques (caracterisees par une phase post-embryonnaire planctonique) and espece holobenthique (caractersisee par unephase post- embryonnaires benthique).
