Antedeans Antedeans are a civilization native to the Alpha Quadrant in the fictional Star Trek universe . They are a race of fish-like humanoids from the planet Antede III . Antedeans find spaceflight extremely traumatic and survive the ordeal by entering a self-induced catatonic state . Upon arrival at the end of a voyage , Antedeans require great quantities of food , known as vermicula to replenish their bodies . Few humans have seen an Antedean in the flesh . Antedeans have unsophisticated minds that could be easily read by Betazoids ; Klingons consider them to be a handsome race . In 2365 , the Enterprise-D escorted two Antedean dignitaries from Antede III to a conference on planet Pacifica . Here the Antedeans were to be given an opportunity to join the Federation . However , upon transport down to Pacifica it was revealed , by Ambassador Lwaxana Troi , that they were in fact assassins and their robes were lined with ultritium . They had planned on blowing up the entire conference. ( TNG : `` Manhunt `` ) Categories : Star Trek races
