The cirri or tentacles, of which three or four pairs are present, are capable of being protruded, and the minute larva swims by means of the ciliary action they produce.
She is unusually intelligent, charming... and then she is pretty, uncommonly pretty, and agile--she swims and rides splendidly... and her voice!
Quinn swims every morning and takes along a cake of soap because he's lazy.
Finally, a mouth is formed by breaking through at the apex of the manubrium, and the now fully-formed medusa becomes separated by rupture of the stalk of the bud and swims away.
A gnat pupa swims through the water by powerful strokes of its abdomen, while the caddis-fly pupa, in preparation for its final ecdysis, bites its way out of its subaqueous protective case and rises through the water, so that the fly may emerge into the air.
A duckling only a few hours old if placed in water swims with orderly strokes.
By the aid of these cilia the larva swims actively, but owing to its minute size it covers very little distance, and this probably accounts for the fact that where brachiopods occur there are, as a rule, a good many in one spot.
A large number of specimens of a species are usually found together, since their only mode of spreading is during the ciliated larval stage, which although it swims vigorously can only cover a few millimetres an hour; still it may be carried some little distance by currents.
With the faeces of the host the larva hatches out and swims freely for a time.
The cercaria swims freely for a time and either encysts directly on grass or weeds or it enters a second host which may be another mollusc, an insect, crustacean or fish, and then encysts.
The larva swims by a ri ig of cilia, which corresponds with the praeoral circlet of a Trochosphere.
Comparatively only a few species are, for part of their lives, denizens of fresh water; these, as larvae, are parasitic on the eggs or larvae of other aquatic insects, the little hymenopteron, Polynema natans, one of the " fairy-flies " - swims through the water by strokes of her delicate wings in search of a dragon-fly's egg in which to lay her own egg, while the rare Agriotypus dives after the case of a caddis-worm.
Two typical forms are in use; in one a liquid is prepared in which the crystal freely swims, the density of the liquid being ascertained by the pycnometer or other methods; in the other a liquid of variable density, the so-called "diffusion column," is prepared, and observation is made of the level at which the particle comes to rest.
In the development of the Hydrozoa, and indeed of the Cnidaria generally, the egg usually gives rise to an oval larva which swims about by means of a coating of cilia on the surface of the body.
The larva for a time swims freely in the sea-water, having a circlet of cilia round the body in front of the mouth, forming the velum.
The glochidium quits the gillpouch of its parent and swims by alternate opening and shutting of the valves of its shell, as do adult Pecten and Lima, trailing at the same time a long byssus thread.
The hare takes readily to the water, where it swims well; an instance having been recorded in which one was observed crossing an arm of 1 Julius Hare's co-worker in this book was his brother Augustus William Hare (1792-1834), who, after a distinguished career at Oxford, was appointed rector of Alton Barnes, Wiltshire.
Bailak Kibdjaki, also, an Arabian writer, shows in his Merchant's Treasure, a work given to the world in 1282, that the magnetized needle, floated on water by means of a splinter of wood or a reed, was employed on the Syrian seas at the time of his voyage from Tripoli to Alexandria (1242), and adds:"They say that the captains who navigate the Indian seas use, instead of the needle and splinter, a sort of fish made out of hollow iron, which, when thrown into the water, swims upon the surface, and points out the north and south with its head and tail" (Klaproth, Lettre, p. 57).
This little creature, which has many of the features of a Trochosphere larva, swims about at the surface of the sea for about a month and grows rapidly.
Of C. coscoroba Mr Gibson remarks (Ibis, 1880, pp. 36, 37) that its "note is a loud trumpet-call," and that it swims with "the neck curved and the wings raised after the true swan model."
Lumber the writing with nothing - let it go as lightly as the bird flies in the air or a fish swims in the sea.
It swims with most of the body submerged, and dives with perfect ease, remaining long without coming to the surface to breathe.
It is often depicted with a flowing tail, which appendix attests close observation of nature; for the mino-game, as it is called, represents a tortoise to which, in the course of many scores of years, confcrvae have attached themselves so as to form an appendage of long green locks as the creature swims about.
The monitor, or forktongued lizard, which burrows in the earth, climbs and swims, is said to grow to a length of 8 to 9 f t.
