Of the 7 species of abalone found in California (Geiger 1999), the black abalone is bathymetrically
the most shallow species, occurring primarily in rocky intertidal habitats (Morris et al.
A high percentage of eggs of Strongylocentrotus droebachiensis are fertilized by sperm of its sympatric (but bathymetrically
displaced) congener S.
Dives with fiat bottoms were classified as Type E dives, which may represent either bathymetrically
constrained dives of seals traveling along the continental shelf or benthic foraging.
These catches usually comprise only young and immature fish bathymetrically
segregated from larger individuals that concentrate on the slope (Valentim et al., 2007), and their potentially high fishing mortality rate may affect adult stock resilience on the slope fishing grounds.
With increasing latitude, the cross-shelf dimension of the range widens as well because the offshore cold-temperature limit is bathymetrically
fixed relative to the inshore range boundary.
