These free-swimming larvae of the Ascidia have been known for a long time.
2
Movement, free-swimming or gliding, with especial tendency to get under clumps of foreign matter.
3
Here the trainees are introduced to free-swimming ascents, or FSAs.
4
In this case, peculiar free-swimming arthropods had formed chains as they swam through the seas.
5
They were identified as free-swimming Thiovulum and Thiospira species.
6
Finally, we examined with mechanical vibration the startle response of free-swimming larvae in 300 mM ethanol.
7
In the wild, bacteria are predominantly associated with surfaces as opposed to existing as free-swimming, isolated organisms.
8
The body is small, globular or oval and either free-swimming or fastened by one of the two flagella.
9
As a rule the germ develops into a stalked polyp, out of which the free-swimming Medusa is formed.
10
The attachment is effected by a number of out-growths, usually three, which can be seen even in the free-swimming larva.
11
Like any other cephalopod, this is a voracious carnivore, targeting all kinds of crustaceans and sea slugs and other free-swimming prey.
12
They are animals, and attach themselves by a muscular base to the rocks or shells, or are as free-swimming as perch.

14
When the free-swimming Amphioxus-larva is three months old, it abandons its pelagic habits and changes into the young animal that lives in the sand.
15
But observation soon revealed that in this world-wide ocean there were many living species, some sessile, others free-swimming, some microscopic, others as large as whales.
16
On polarized epithelia, Hp is able to grow directly on the apical cell surface in conditions that do not support the growth of free-swimming bacteria.
