Hi Verso,
* 8D. 'unusual example of marine life' = 'sea snail'
The letters of - LIES, AS, AN - are an anagram of 'sea snail'
* 22A. 'perceive intuitively' = 'divine'
like a god = divine
* 15D. 'fire up' = 'ignite'
take the 'lad' from 'detailing' (lad's departure), and you are left with the letters to spell 'ignite'
* 26A. 'gets tired' = 'wearies'
ram = aries
ewe mostly = most of the word 'ewe', which is 'ew'
EW+ ARIES = wearies
