sentence: Mature adults have a pair of ear-like fins.
sentences_after: These fins stand out from the lateral sides of the mantle. Their powerful beak-like jaws are as white as ivory. Within the webbing are two pouches. These pouches hide the tactile 'velar filaments'. The filaments are analogous to a true squid's tentacles, extending well past the arms, however, they are a different arm pair than the squid's tentacles.
