Underwater peaks- analogues to mars?

Correction on those links:

A recent Mars Express image reminded of the form of peaks sometimes
seen underwater. Look at the sonogram below of the Adare seamounts:

See also the first image on this page:

These images of underwater peaks show separate, conical peaks
closely
spaced.

They may be analogous to this image of Eos Chasma:
