In addition, various marine vertebrates augment these physiological traits using a range of behavioral responses that are believed to extend time spent underwater (Kramer, 1988).
More recently advanced laboratory prototypes of the displacement immunosensor have been fabricated to improve low-end detection, extend the applications to underwater sensing, enhance field ruggedness, and assist in the manufacturing process.
What makes this design unlikely is that destination ports would have to be completely redesigned to accommodate a ship that extends this far underwater.
In particular, it can successfully germinate by extending a coleoptile underwater in the complete absence of oxygen (Magneschi and Perata 2009).
