Aphroditids are carnivorous opportunistic predators, specialized in slow or sessile preys (Fauchald & Jumars
, 1979), feeding on a wide variety of prey, like other annelids, small crustaceans, mollusks and diatoms (Pettibone, 1953).
Diffusional deposition of particles is also possible (Shimeta 1993), as are mechanisms involving inertial forces when Reynolds number at the filaments exceed 0.1 (Shimeta & Jumars
1991, Ward 1996).
Pisionidens indica is known to inhabit the dynamic surf zone of tropical beaches and is well adapted to burrowing in sands (McCarthy, Laws, Estabrooks, Bailey-Brock, & Kay, 2000; Jumars
, Dorgan, & Lindsay, 2015).
Los especimenes hallados se agruparon en los seis gremios troficos: depositivoros superficiales, depositivoros subsuperficiales, carnivoros, herbivoros, filtradores y omnivoros; segun la revision actualizada de Jumars
(2015), sobre el articulo de Fauchald & Jumars
Suspension-feeding animals generally have mechanisms for efficiently directing water to food-collecting surfaces, and then efficiently and effectively capturing available food particles from the incoming seawater (reviewed by Yonge, 1928; Jorgensen, 1955, 1966; Shirneta and Jumars
, 1991; Ward and Shumway, 2004; Riisgard and Larsen, 2010).
Probably, the deposition of algae within the crevices is due to the accumulation of debris in them and the possible establishment of refuges (Bergey, 1999; Nowell and Jumars
, 1984; Davis and Barmuta, 1989; Snelgrove et al., 1993).
By now we had reached the bottom of the ropes fixed by Greg and George, so all we had to do was clip our jumars
to the lines and half-climb, half-pull on the jumar
as we ascended--but now I discovered that Cronlund did not have an ascender of any kind.
Mark Wellman--the first paraplegic to climb E1 Cap--just did straight pull-ups using Jumars
, which are clamps that slide up the rope and lock when you pull down on them.

With her harness and helmet and Jumars
(mechanical rope ascenders), Nadkarni is a scientist able to connect with a popular audience.
