Distal

Distal: Near or toward the free end of a structure; opposite of basal.

Anthocodia: the distal end of an octocoral polyp, usually the mouth and the 8 tentacles.
Anthostele: The lower part of the polyp, often stiffened, into which the distal portion of the polyp, the anthocodia is withdrawn.

Distal - The end of a branch or remotely situated from the center.
Dorsal directive septum - Part of the septal configuration of Porites.

The absence of chin-bar (vs. presence in B. pugnax, B. prima and B. pulchra); presence of dark distal borders on anal and caudal fins (vs. absence in B. Pugnax, B. fusca, B. schalleri, B. prima and B. pulchra; absence of caudal transverse bars (vs.

Dorsal fin with black spot on distal part of anterior rays. Anal fin with 4-5 simple rays, 9-11 branched rays. Upper jaw and 4th ceratobranchial toothless; lower jaw with few conical teeth in pocket or depression near symphysis.

The abdomen and post-abdomen (distal to the anus) is generally bent forward under the thorax. The post-abdomen bears two large claws used primarily for cleaning debris out of the carapace.

In terms of spermatogonia distribution, the structure of teleosts testes has two types: in the most commmon, spermatogonia occur all along the seminiferous tubules, while in Atherinomorph fishes they are confined to the distal portion of these ...

It blooms from the base to the tip over a few days, shedding a thin dry film as it opens. The long (about 30+cm.) vertical inflorescence consists of a thin stalk covered on the distal 8-16 cm with numerous tiny white or pink flowers.

Damage often occur at the gills and it may be the only affected area. (Gill lesions are characterized by necrosis of the distal end of the gill filament which progresses basally to involve the entire filament.) ...

This species is readily discerned from all the other rosy tetra species by the dark colour pattern on the posterior part of the anal fin that expands from the black distal (furtherest from the body) border of this fin.
