 issued from : G.A. Boxshall inPhil. Trans. R. Soc. Lond., 1985, B 311. [Plate 1, 47-49]. 47, button seta on Mx2, showing zone of transition between normal setule and button; 48, back and side views of button setae; 49, detail of buttons. Scale bars: 0.010 mm (47-48; 0.002 mm (49). The transition from normal setule to stalked button occurs over a short distance and shows that the buttons are modified setules. Their paired arrangement and stalks are also shown in figures 48 and 49. Itis assumed that the button setae are involved in prey capture and holding. Their position on the distal portions of the raptorial limbs also suggests a role in the grasping action. There are 11 button setae, only 4 on the maxilliped, here interpreted as evidence of the dominant role of the maxillae in prey capture. The role of the buttons themselves is unclear. It is probably to increase the surface area of the seta that comes into contact with the prey and to protect these primary feeding setae from damage. The stalked buttons may act as buffers, absorbing some ofthe energy generated by the struggling prey, thereby protecting the seta, which cannot be replaced once damaged as adult copepods do not moult. The prey is grasped directly by the button setae.

Overall Drpth Range in Sargasso Sea: 500-2000 m (Deevey & Brooks, 1977, Station "S");
This species appears to exhibit a considerable variation in size.
After Esterly (1991, p.334) the shape of the head recalls that of A. (= Centraugaptilus) horridus Farran (1908, p.78, pl.8, fig.29). For Brodsky (1950) this species is not a synonym because the exopodite of P1 2-segmented. [But, it is posible to overlooked the line of separation between the the sgments 2 and 3]. | | | Last update : 03/12/2020 | |
