When our crustacean outgrows its borrowed habitation, it sets out in search of another shell, a little larger, and better suited for its increased size.

When the bivalve half opens its shell to enjoy the rays of the sun or take food, the evil-disposed Crustacean slips a stone between the valve.

A crustacean possessed of but little generosity is the Lithoscaptus of Mons.
Faujas de Saint-Fond has mentioned a fossil hermit-crab as found in the mountain, St. Pierre de Maestricht; but he called by this name a crustacean of the genus Callianassa and not a pagurus.
Among the Philippine Islands, also, a brachyurous crustacean lives in the branchial cavity of one of the Haliotidae, and another on the body of a holothuria.
This crustacean is an Anilocrian so common that we can scarcely imagine it to have escaped the attention of any naturalist.
It is probable that the Euplectella of the Atlantic, recently observed near the Cape Verd Islands by the naturalists on board the Challenger, also conceals this crustacean in its interior.
One of the ancient Eurypterids from the Old Red Sandstone of Europe has a length of six feet, which is more than three times that of any Crustacean now living.
While a gigantic Isopod Crustacean from the same strata had a leg the basal joint of which was three inches long, and three-quarters of an inch through, which is larger than the whole body of any modern species.
This little crustacean is associated in its work on submerged timber with the isopod /Limnoria lignorum/.
Huxley describes the barnacle as a crustaceanfixed by its head and kicking food into its mouth with its legs.
The crustacean that you speak of is a Vibilia, the first taken in the British Islands.
These forms are amongst the most interesting things I have seen for a long time, because it would almost seem as though we had a Crustacean with three phases, just as the bee has—male, female, and worker.
I wonder that our fishermen do not destroy them also, as they feed upon a certain crustacean (Carcinus mænas) which is often used for bait.
There was one Crustacean about which some difficulty had arisen.
And were I to return to my own place by sea, and undergo shipwreck, the crustacean might, and probably would, return the compliment, and demonstrate our common nature by turning my protoplasm into living lobster.
If digestion were a thing to be trifled with, I might sup upon lobster, and the matter of life of the crustacean would undergo the same wonderful metamorphosis into humanity.

Taking the first of these groups of fossils, we may recognise in the Leperditia a two-valved Crustacean closely allied to forms still living in the seas and fresh waters.
At length, as perfected larvæ, they are, together with their crustacean hosts, transmitted to the stomach of the ultimate or human bearer.
The limits of this work preclude my attempting a more extended notice or enumeration of the crustacean and arachnidan parasites.
The larvæ then proceed to coil themselves within the limbs, as many as six or even a dozen of the parasites being occasionally found within the body of a single crustacean host.
At last the young entozoon completely fills the interior of the embryo, the latter having scarcely undergone any change, and still remaining, of course, within its crustacean host.
Some species are parasitic on crustacean parasites that are themselves attached to marine fishes.

If the raven fails he turns the shell over and over until the impatient crustacean allows a claw to emerge; he is then seized and immediately devoured.

A larval form with the above characters occurs with more or less frequency in all the Crustacean groups.
The independent origin of the Ostracoda from the main Crustacean stem seems probable.
Claus speaks of the various Crustacean phyla as having sprung from a Protophyllopod form, and it might be supposed that he considered that they all diverged from the same form.

Amongst the many interesting observations on the Crustacean ova I will only allude to those of Weismann on the ova of Leptodora, a well-known Cladoceran form.
He therefore postulates the earlier existence of a Protophyllopod form, which would correspond very closely with the Nauplius as reconstructed above, from which he believes all the Crustacean groups to have diverged.
In fact, in the embryo, we trace the one form into the other; for the crab is at first a long-tailed crustacean (Fig.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "crustacean" in a variety of sentences. We hope that you will now be able to make sentences using this word.
