All those studies are from either shallow GoM seeps or the Menez Gwen vent field, i.e. < 1000 m deep (and Ana Colaco tells me that the B. azoricus population at the nearby 1700 m deep Lucky Strike vent field does not show seasonality). I'm having another look at Bythograea thermydron; Perovich et al. (2003; MEPS) proposed it as seasonal, from a nice time-series of samples. But I have a few nagging doubts about some methodology (not at all a criticism of Perovich et al., as the bit that's worrying me was done in our lab!). It may well be seasonal - if so, it would be one species from beyond the dysphotic zone, raising interesting questions about cues. The other two species I think may need re-evaulation are Calyptogena kilmeri (Lisin et al., 1997; Invert Repro Dev) and Buccinum thermophilum (Martell et al., 2002; J Moll Stud), for various reasons that I hope to go into in a future review paper.

Can you tell me what those four species are (I know one is B. childressi)? Excellent overview Jon! Can you tell me what those four species are (I know one is B. childressi)?
