Mae Kevin Hawke yn blymiwr brwd ac yn wirfoddolwr gyda Moroedd Byw/ Living Seas Wales. Dyma delwedd gafodd ei chymryd o'i log plymio sy'n cofnodi ei dro cyntaf un yn plymio yn St Brides Bay ar 6 Mai 1996. Tra oedd yn y dŵr fe sylwodd ar lawer o fywyd gwyllt morwrol- ac mae'n eu disgrifio yn adran "Dive Details" y llyfr log (trawsgrifiad isod):
Dive Details: Kitted up in the car park, carried out buoyancy check in shallow water - 28lbs on weight belt. Planned to go in as a four some but Barry had buoyancy problems. So Phill and I carried out the dive as a pair. Had some difficulty getting under the water - had to swim under. Relaxed + confident and also excited. Saw a large red fish almost immediately which Phill said was a wrasse. Lots of different kinds of crabs which in keeping their distance from us fanned out in a semi-circle in front of us. Brilliant.
