The diagnosis of this genus is largely based on features of the cirri and arms, and is thus of only limited relevance to the present specimen. |
|
The ventral nerve chord and nerve bundles of the maxillary cirri are indicated. |
|
The nape lacks cirri, and the first gill arch attaches to the operculum, the latter characteristic distinguishing Tripterygiidae from Clinidae. |
|
After scaling a sea fan, the feather star might stay for a while, hanging on by means of tiny hooks called cirri. |
|
In unstalked crinoids, the cirri are located on the end of the calyx opposite the mouth, and are used by the animal to grasp the substratum. |
|
Other common elements may include the possession of fixed conical teeth and cirri, or fleshy hair-like projections, on the head. |
|
The trivial name nudus refers to the lack of cirri on the column of this new species of Camptocrinus. |
|
In barnacles the cirri filter tiny bits of food from the water and then transfer them to the mouth. |
|
The barnacle opens the movable plates and its feathery legs, called cirri, act like plankton nets and rhythmically sweep the water. |
|
A thin, chitinous cuticle covers the appendage-bearing portion of the body, including the cirri, mouthparts, and lining of the mantle cavity. |
|
This reflex results in the rapid withdrawal of the cirri, which are otherwise vulnerable to predation, especially by fish. |
|
Some studies suggest that the barnacle's cirri can be extended and retracted 140 times per minute. |
|
Muller and Westheide found the innervation pattern of myzostomid parapodia and marginal cirri to be identical to that of polychaete parapodia and cirri. |
|
The head is often blunt and typically adorned with tentacles or cirri. |
|
Sometimes conidia are extruded through ostioles in whitish cirri. |
|
The presence of aciculae and well developed parapodial lobes with cirri in Rollinschaeta clearly invites comparison with living aciculate polychaetes. |
|
They differ from acorn barnacles in that the plates do not form a separate wall and operculum and in having the wall and the cirri it contains elevated above the substratum by a peduncle. |
|
The blue sky is glossy and fat with heat, a few thin cirri sheared to blown strands like hair at the rims. |
|
Count how often barnacles move their cirri in one minute. |
