moneyman6891 Posted March 2, 2009 Share Posted March 2, 2009 I got my first clam after a long time of wanting one. What do you think, its about 2 1/2 inches and real healthy. edit: for some reason when I load pictures onto photobucket from my computer at home it gets lines in the picture. Link to comment
davidr2340 Posted March 2, 2009 Share Posted March 2, 2009 You have a great clam right there!!! Link to comment
moneyman6891 Posted March 2, 2009 Author Share Posted March 2, 2009 I dont know what kind, my buddy at the lfs said theyve had it for a few months and gave me a great dal for it. Link to comment
skydive Posted March 2, 2009 Share Posted March 2, 2009 Can you post a picture showing the shell? Link to comment
reefman225gal Posted March 2, 2009 Share Posted March 2, 2009 Very nice clam me like a lot. Link to comment
b_c_fisher Posted March 2, 2009 Share Posted March 2, 2009 anyone seen the crocea/maxima hybrids? kinda looks like one Link to comment
pismo_reefer Posted March 2, 2009 Share Posted March 2, 2009 anyone seen the crocea/maxima hybrids? kinda looks like one craxima's? Link to comment
basser1 Posted March 2, 2009 Share Posted March 2, 2009 anyone seen the crocea/maxima hybrids? kinda looks like one That's because there isn't any "hybrids". If so, we would've seen them over the course of a million years, give or take a few. BTW, I agree with BK.... very nice crocea! Link to comment
moneyman6891 Posted March 2, 2009 Author Share Posted March 2, 2009 thanks for the compliments Link to comment

lakshwadeep Posted March 3, 2009 Share Posted March 3, 2009 Maybe there are?http://www.reefbuilders.com/2009/02/28/max...full/#more-5038 I'll wait for the genetic test. Link to comment
basser1 Posted March 3, 2009 Share Posted March 3, 2009 Maybe there are?http://www.reefbuilders.com/2009/02/28/max...full/#more-5038 Yeah, I also looked at the comments at the bottom of the page, looks like the jury is still out on this one. Link to comment
b_c_fisher Posted March 3, 2009 Share Posted March 3, 2009 Well I'll tell ya from looking at the last ones my LFS ordered you can definately see Maxima coming out with the Crocea. I don't think it would be impossible as they are genetically not much different. Really in a small tank that's like Flowerhorns think about it a Crocea spawns and a Maxima spawns not that hard to imagine. Plus like I said these things looked like Crocea shells just longer "Fins" and they definately had the mantle of a Maxima but with NO DOUBT Crocea colors or else damn someone made some UGLY maximas.

reefman225gal Posted March 4, 2009 Share Posted March 4, 2009 I wonder what's so hard to believe that clam hybrids exist. I found this info in Delbeek and Sprung's book. Tridacnid clams are simultaneous hermaphrodites.(i.e.they possess functional sets of both male and female gonads) and reach full sexual maturity after about 5-7 years. The age of maturation is different for each species ( Heslinga, et al., 1990). Some clams can become sexually mature as males within two years and then gradually acquire female gonads as they mature further ( LUCAS,1988). Although clams posses both male and female sex organs at maturity, the release of sperm and eggs are separate events.This tends to prevent self-fertilization. Generally, the sperm are released into the water first, followed shortly thereafter by the eggs. Self-fertilization, and cross-fertilization between different species can occur ( Alcazar, 1988). Hybrids can be formed that exhibit characteristics of both species. Known and suspected hybrids. include Hippopus hippopus x H. porcellanus ( Alcazar, 1988), T. maxima x T. crocea, T.derasa x T.gigas, and T.maxama x T.squamosa ( J. Sprung per. obs.; G. Heslinga, pers. comm.) Edit: Spelling Link to comment

Think about it, if this were possible, why haven't we seen any in the ocean? Especially after millions of years of evolution and cross breeding? Link to comment
cody6766 Posted March 5, 2009 Share Posted March 5, 2009 it could be the same reason you see hybrid african cichlids in many tanks, but not in lake malawi. Malawi is packed with cichlids, but they find their own mates. I'm sure there are a few hybrids, but they aren't common. I bet the situation exists within this clam genus too. I also would wager that hybrid + hybrid offspring isn't very viable or possible, eliminating common observations in the wild and the development of of hoards of new species. Link to comment

The link I've provided below is by James Fatheree, and if you scroll down to the final note of that article he talk's about hybrids. http://www.reefkeeping.com/issues/2002-07/...ature/index.php Edit: So he's saying there are hybrids. I just think they haven't been described ( Taxonomic classification) as for the scientific evidence you talk about. I don't think it means they don't exist. Link to comment
tangsrmyfriends Posted April 8, 2009 Share Posted April 8, 2009 Well, I'm a beginner, and it all start with my boyfriend who is into Reef Aquariums. The more I seen how fascinating it was. I became interested in it too. I just looked in my book The Conscientious Marine Aquarist, and the OP's clam looks like a Tridacna crocea. Edit: Spelling Link to comment
iMaGin3 Posted April 9, 2009 Share Posted April 9, 2009 i would say crocea also. however if it is a hybrid, would it be sterile? like horse + donkey = mule (sterile) Link to comment
