      These may seem like rather bizarre characteristics but they are actually ancestral and apparently quite ancient. A third group of Octopodiformes, Vampyromorpha or vampire squids, diverged from the cirrates and incirrates some time in the Paleozoic (+ mya) according to a recent molecular analysis by Strugnell et al As demonstrated by the excellent Tree of Life webpage vampire Author: Cameron Mccormick. After capture, deep-sea squid are often dead by the time they reach the surface. The only deep-sea cephalopods that have been reared under laboratory conditions for extended periods of time were captured by submersibles and include cirrate octopods and vampire squid (Hunt, , Jacoby et al., , Robison et al., , Hoving and Robison, ).Cited by: 5.

    Deep sea cirrate octopods have glowing suckers on their arms that might attract prey items. See additional information sources in the comments. Such a diversity of uses for light in the dark demonstrates its critical importance to deep water communities and shallow water species alike. Introduction. Members of this family are the best known of the octopods. There is considerable diversity within this family. They range in size from pygmy species mature at under one gram (e.g., Octopus wolfi) to the Giant Pacific Octopus (Octopus dofleini) of the North Pacific reaching weights in excess of kilograms with an arm span of over 5 m.

    In the deep-sea, the main incirrate octopods such as Bathypolypus, Benthoctopus and Graneledone, have very large eggs, suggesting benthic hatchlings [–]. In this bathyal and abyssal environment, the suborder of the cirrate octopods probably represents an exception to the by: - Explore mightyaxel's board "OCTOPODS/SHRIMP/CRAB/LOBS", followed by people on Pinterest.

The cirrate octopods are deep-sea, cold-adapted cephalopod molluscs that are found throughout the world’s oceans, usually at depths in excess of m, but shallower in cold water at high latitudes.

and arc restricted to tissues associated with the oral ring the base of the arms (Herring et al., ). In the case of cirrate octopods, bioluminescence has been suggested but never confirmed (hldred et al.,; Vecchionc, ). This study provides the first description of biolumines. The behaviour of cirrate octopods of the genera Cirroteuthis and Grimpoteuthis in their natural habitat was studied using video recordings.

Sequences were filmed during the French cruise “Faranaut”, from the manned submersible “Nautile” at depths between and m, in two zones in the Fifteen-Twenty Fracture Zone on the Mid-Atlantic Ridge. Four different modes of active Cited by: How do organisms of the deep sea attract mates.

Describe the angler fish's interesting solution to the problem of finding a mate in the deep sea. Chemical attractants and bioluminescence help bring mates together Angler Fish - male parasitism; female will excrete chemicals that will attract a male.

Once the male finds the female, it will merge. Abstract. Seagrass meadows have been shown to be highly productive and of great value to nearshore marine regions.

In addition to the utilization of their production by both direct grazing and detrital food chains, considerable amounts of seagrass are transported offshore, often to great distances, where it may serve as food for both surface feeding and benthic feeding by:   Deep-sea octopods are easily separated into two distinct groups: (1) the cirrate, or finned, octopods (also known as “dumbo” octopods), characterized by fins on the sides of their bodies and fingerlike cirri associated with the suckers on their arms and (2) incirrate octopods, which lack both fins and cirri and are similar in appearance to.
