The same is true of the chitinous gladius of squid [83] and octopuses. [84] Cirrate octopods have arch-shaped cartilaginous fin supports, [85] which are sometimes referred to as a "shell vestige" or "gladius". [86] The Incirrina have either a pair of rod-shaped stylets or no vestige of an internal shell, [87] and some squid also lack a gladius ...
[4] [5] For example, a large marine vertebrate may eat smaller predatory fish but may also eat filter feeders; the stingray eats crustaceans, but the hammerhead eats both crustaceans and stingrays. Animals can also eat each other; the cod eats smaller cod as well as crayfish, and crayfish eat cod larvae. The feeding habits of a juvenile animal ...

Eggs hatch in seawater, and larvae are eaten by crustaceans, usually euphausids. The infected crustaceans are subsequently eaten by fish or squid, and the nematodes burrow into the wall of the gut and encyst in a protective coat, usually on the outside of the visceral organs, but occasionally in the muscle or beneath the skin.
The shapes of these virus particles range from simple helical and icosahedral forms for some virus species to more complex structures for others. Most virus species have virions that are too small to be seen with an optical microscope. The average virion is about one one-hundredth the linear size of the average bacterium.
Crustaceans. Squid. Octopus. They use their unique sensory function, electroreception, and 360 vision to find their prey and pin them down so they can’t swim away. Predators and Threats.
The squid’s nerves and muscles control whether the sac is expanded or contracted. When it expands, it’s like a balloon filling up with a colored liquid. When all of the chromatophores across ...
Squid in the family Pyroteuthidae have Photophores (small, light-producing organs) on viscera (internal organs), stalk of tentacles, and five large and ten small photophores underneath the eyes. [4] The squid has a wide, triangular mantle with a rounded posterior end and rounded fins on the distal dorsal end of the mantle. [5]
