- The skull is a bony structure in the head of most vertebrates (in particular, craniates) that supports the structures of the face and forms a protective cavity for the brain.The skull is composed of two parts: the cranium and the mandible.he English word skull is probably derived from Old Norse  skalli  meaning bald, while the Latin word cranium comes from the Greek root κρανίον (kranion). The skull is made of a number of fused flat bones.

- Knowing how much I've traveled around the U.S., people sometimes ask me where's the best place to live in America, but of course, I can't answer that, since each state is unique and special in its own way, and everyone looks for different things, and at different times in their lives.

Barnacle Description [edit]. Barnacles are encrusters, attaching themselves permanently to a hard substrate. The most common, acorn barnacles (Sessilia), are sessile, growing their shells directly onto the substrate. The order Pedunculata ( goose barnacles  and others) attach themselves by means of a stalk. ring of plates surrounds the body, homologous with the carapace of other crustaceans. These consist of the rostrum, two lateral plates, two carinolaterals, and a carina. In sessile barnacles, the apex of the ring of plates is covered by an operculum, which may be recessed into the carapace.

Beating the barnacle A curious idea but strangely, one that caught on and several writers of the time described how barnacles turned into birds. The stalked barnacles, today known as goose barnacles, are seldom a serious problem on boat hulls.

Barnacle Barnacle is a small but a hardy saltwater animal belonging to Arthropoda phylum along with being put in the class Crustacea and the order Cirripedia. Barnacles are usually found attached to ships, rocks, wharves, marine animals and to other hard surfaces. Acorn barnacle, Brown Buckshot barnacle, Goose barnacle and Thatched barnacle are some common types of barnacle. Barnacles are closely related to lobsters and crabs as they too have a hard outer cover.

Arthropods: Lobsters, Shrimps, Crabs, Barnacles and the âPodsâ Crustaceans are equipped with jointed appendages and a hard external skeleton (exoskeleton) which we often call the shell. The shell is usually jointed. Most soft body parts are contained within the shell. The bodies of crustaceans display bilateral symmetry, meaning that the body is organized fore and aft.Crustaceans have a definite brain in the head at the front of the body.arnacles develop from an egg into a larval stage in a manner similar to lobsters, shrimps and crabs. Barnacles also possess the jointed appendages found in other crustaceans. But barnacles only display some of these characteristics as larvae.

Barnacle The sessile lifestyle of barnacles makes sexual reproduction difficult, as the organisms cannot leave their shells to mate. To facilitate genetic transfer between isolated individuals, barnacles have extraordinarily long penises⁠. Barnacles probably have the largest penis to body size ratio of the animal kingdom.

- NOTE the video replays automatically. A 26-mo study on growth and reproduction of goose barnacles Pollicipes polymerus at 2 sites in San Juan Island, Washington shows that growth is fast during the first year, to a rostrum-carina length of 17mm, but subsequently slows to 2mm. yr-1.Breeding in this area occurs in late April to early October.esearch study 5. Juvenile goose barnacles Pollicipes polymerus use a different mode of feeding from adults. Instead of holding their cirri out into the water flow the way the adults do, the juveniles slowly beat their cirri in the manner of acorn barnacles.

Acorn Barnacle Barnacles, somewhat surprisingly, are crustaceans (like crabs, lobsters, krill, etc.). Unlike most crustaceans, however, adult barnacles are sessile – they can’t move. After a short phase spent as planktonic larvae, barnacles settle, attach to a hard substrate, and never move again. The Acorn Barnacle is one species in a large group of species with the same common name that do not have stalks and instead attach their shells directly to the substrate. Gooseneck Barnacles are a common example of the stalked variety.

The evolution of mating systems in barnacles In this paper, we review theory and existing empirical data regarding the evolution and diversity of barnacle mating systems. We begin by discussing variation in mating systems among species, and predictions about the evolution and stability of hermaphroditism, androdioecy and dioecy in barnacles.ndrodioecy in barnacles has proved difficult to study because it is most prevalent in deep water scalpellids. More complete knowledge of the natural history and reproductive biology of these species would improve our understanding of the evolution of androdioecy and dioecy.

- Marine Worms-Nemertea (Ribbon worms or Proboscis worms). Nemertea is a phylum of invertebrate animals also known as Ribbon worms. They are also known as Proboscis worms because they can extend a proboscis to capture their food. There are about 1,400 species of ribbon worms nearly all of which are found in oceans around the world. Most species live on or in the sea floor, with many species found in brackish water in estuaries, and even some freshwater and land-based species. Their habitats include-in and among seaweeds, rocks, mussel and barnacle beds, under shells or buried in mud, sand, or gravel substrates.

Barnacle Barnacles attached to the ventral pleats of a humpback whale calf. A barnacle is a type of arthropod constituting the infraclass Cirripedia in the subphylum Crustacea, and is hence related to crabs and lobsters. Barnacles are exclusively marine, and tend to live in shallow and tidal waters, typically in erosive settings.

Description & Behavior All octopuses in the genus Grimpoteuthis are nicknamed dumbo octopuses, due to the ear-like fins that protrude from the sides of their mantles just above their eyes which resemble the elephant ears of the Disney character Dumbo. Grimpoteuthis octopuses are part of the Cirrina suborder.
