Etymologies

Sorry, no etymologies found.

Examples

  • The cephalopoda are the only locomotive animals in which the distinction of upper and lower does not exist.

    On the Generation of Animals

  • The con also picked up our tab tickets, Coke, popcorn, ride for the Thursday Midnight Showing of Pirates of the Caribbean 2: Keira's Sunburn, which was pretty awesome, but I speak as a fan of Davy Jones, cephalopoda, and Keira's sunburn, so I may not be the most objective source.

    Kenneth Hite's Journal

  • The uterus is also double in the crustacea and the cephalopoda, for the membranes which include their so-called eggs are of the nature of a uterus.

    On the Generation of Animals

  • To speak generally, if we take all animals which change their locality, some by swimming, others by flying, others by walking, we find in these the two sexes, not only in the sanguinea but also in some of the bloodless animals; and this applies in the case of the latter sometimes to the whole class, as the cephalopoda and crustacea, but in the class of insects only to the majority.

    On the Generation of Animals

  • But we cannot say simply that all bloodless animals produce a scolex, for the classes overlap one another, (1) the insects, (2) the animals that produce a scolex, (3) those that lay their egg imperfect, as the scaly fishes, the crustacea, and the cephalopoda.

    On the Generation of Animals

  • Sometimes also cephalopoda unite by the male mounting on the back of the female, but whether for generation or some other cause has not yet been observed.

    On the Generation of Animals

  • In the cephalopoda (as also in the crustacea) the same passage serves to void the excrement and leads to the part like a uterus, for the male discharges the seminal fluid through this passage.

    On the Generation of Animals

  • Some animals manifestly emit semen, as all the sanguinea, but whether the insects and cephalopoda do so is uncertain.

    On the Generation of Animals

  • Both these eggs and those of the cephalopoda grow after deposition like those of fishes.

    On the Generation of Animals

  • The young are produced in the same way also by the cephalopoda, e.g. sepias and the like, and by the crustacea, e.g. carabi and their kindred, for these also lay eggs in consequence of copulation, and the male has often been seen uniting with the female.
