GVI Corals Mexico
Cards in this deck (50)
- 1—Porites asteroides
Mustard Yellow to Brown. Medium-sized boulders, possibly slightly fuzzy if the polyps are out. Coralites are small in size and close together. polyps don't portrude - 2—Siderastrea radians
The holes are on the surface and look a bit like a (official term!) cat's anus. Sid. siderea holes in comparison are slightly recessed.
- 3—Siderastrea siderea
Basically looks like a lump of clay which someone pricked with a pencil. The holes are generally rounder and have neater edges than Sid. radians.
- 4—Stephanocoenia intersepta
Dark polyps/coralites (with white/green centre) on a bright background. Looks a bit like Cheerios in a bowl of milk!
- 5—Montastraea cavernosa
Very fleshy, large polyps which are pretty distinct from each other
- 6—Orbicella faveolata
Up-close the polyps/coralites of the Orbicella genus look a bit like small volcanos. This species has a continuous coverage of the underlying rock, looking like a sheet spread over a lumpy surface
- 7—Orbicella faveolata
Up-close the polyps/coralites of the Orbicella genus look a bit like small volcanos. This species has a continuous coverage of the underlying rock, looking like a sheet spread over a lumpy surface
- 8—Orbicella franksi
Up-close the polyps/coralites of the Orbicella genus look a bit like small volcanos. This species also covers the underlying rock continuosly. Unlike faveolata, the tips of it's lumps are bright
- 9—Favia fragum
Small in size with generally rounded holes. Somewhat similar in appearance to D. stokesii, but is usually not as large and the "mouths" of the holes don't portrude.
- 10—Dichocoenia stokesii
Has elongated holes with slightly portruding edges. Usually larger in size than Favia fragum
- 11—Solenastrea bournoni
colonies are found on the sand or "fore reef" (rather than on the reef itslef), corralite rims portrude. Smooth dome with some irregular bulges
- 12—Solenastrea hyades
colonies are found on the sand or "fore reef" (rather than on the reef itslef), corralite rims portrude. Wide base with pinched waist, some irregular knobs on surface
- 13—Diploria labyrinthiformis
Has double ridges which are separated by a shallow groove. These ridge pairs are in turn separated by deeper grooves
- 14—Pseudodiploria strigosa
Similar to Diploria lab., but only has a single ridge separated by a single groove. Forms a smooth dome with regular-pattern labyrinth
- 15—Pseudodiploria clivosa
Similar to Diploria lab., but only has a single ridge separated by a single groove. Has a more irregular surface than P. strigosa, which also has lumps. Less regular pattern.
- 16—Colpophyllia natans
Labyrinthiform-ridges. Notable: Ridges have a "zipper-like" appearance, with a seam running down the middle of them. A slightly less pronounced "zipper" can usually also be seen in the valleys.
- 17—Manicina areolata
one continuous ridge running along outside. small in size
- 18—Meandrina meandrites
thick ridges with very pronounced septa.
no visible separation between ridges, no valley space visible
- 19—Meandrina jacksoni
thick ridges with very pronounced septa.
some separation between ridges, valley space visible and white colour
- 20—Dendrogyra cylindrus
distinctive fuzzy tower-like appearance
- 21—Mycetophyllia lamarckiana
Mycetophyllia spp: like a meadow surrounded by fence. flat-ish
lamarckiana: "lame that mark and ana have no sheep" => no white/red spots (can have pale spots)
- 22—Mycetophyllia aliciae
Mycetophyllia spp: like a meadow surrounded by fence. flat-ish
aliciae: "alice has loads of sheep" => white spots
- 23—Mycetophyllia ferox
Mycetophyllia spp: like a meadow surrounded by fence. flat-ish
ferox: "the feral wolf killed all the sheep, leaving the fields bloody" => red spots
- 24—Isophyllia sinuosa
hemisphere. thick, fleshy ridges with slight groove running down the centre of them. labyrinth of ridges
- 25—Isophyllia rigida
hemisphere. thick, fleshy ridges with slight groove running down the centre of them.
looks like rock with net thrown over it.
- 26—Eusmilia fastigiata
looks like bouquet of flowers
individual polyps have long stems and portruding septa at the head
- 27—Mussa angulosa
thick-walled fleshy rings with distinct spaces in between them
- 28—Scolymia spp
thick, fleshy walled single-polyp colonies. look a bit like disk-shaped flowers
- 29—Helioseris cucullata
"Like helicopter over water" => distinct waves raditing out from a point toward edges. "lines" on those ridges point toward centre
- 30—Agaricia fragilis
small coral plate with upturned edges (which are often white in colour)
agaricia-pattern visible but less pronounced
- 31—Agaricia lamarcki
distinctive "Agaricia" pattern. has WHITE (not just pale) polyps which look like very pronounced stars
- 32—Agaricia agaricites
distinctive "Agaricia" pattern. agaricites has long "troughs" in which multiple polyps are located. Can have many differnt growth forms.
- 33—Agaricia tenuifolia
distinctive Agaricia pattern. Grows in thin sheets which together look like a head of lettuce
- 34—Agaricia humilis
Also has a rather distinct Agaricia-pattern. Unlike agaricites, humilis has no "throughs" with multiple polyps. Instead, polyps are located in single (or few) holes surrounded by distinct edges
- 35—Acropora cervicornis
Coral with coarse-looking surface (polyps cylindrical in shape). Grows in long branches, which look like a shrub or treebranches.
- 36—Acropora palmata
Usually large, with coarse surface (polyps cylindrical in shape). "Branches" are flat and have a vaguely palm-frond-esque shape
- 37—Acropora prolifera
hybrid of stahorn and elkhorn
Multiple shorter branches growing out of a single node. Those branches are closer together than in cervicornins. (also here polyps cylindrical in shape)
- 38—Madracis auretenra
form dome-like outline with "fingers", which are all very similar in length.
small, portruding polyps
- 39—Madracis decactis
look like a number of small potatoes close together.
small, portruding polyps
- 40—Madracis spp.
small, portruding polyps. many growth patterns
- 41—Oculina diffusa
long, thin branches of pale colour with portruding polyps
rare
- 42—Porites spp
not as regular in shape as M. auretenra, polyps don't portrude
- 43—Porites spp
not as regular in shape as M. auretenra, polyps don't portrude
- 44—Porites spp
not as regular in shape as M. auretenra, polyps don't portrude
- 45—Millepora alcicornis
Fire coral! Very distinctive coloration. Alcicornis can predate other corals/structures and take many different forms. Millepora can hybridize
- 46—Millepora complanata
distinctive coloration. Has flat "blades" of coral, with little to no crossing of blades
Millepora can hybridize
- 47—Millepora striata
distinctive coloration. also has flat blades of coral, but these cross, giving a convoluted appearance.
Millepora can hybridize
- 48—Millepora squarrosa
Distinctive coloration, but more diminuitive than other forms of Millepora. Has small ridges which cross and form square-like shapes.
- 49—Stylaster roseus
Usually flat bush/tree-like appearance, purple to pink in colour
- 50—Orbicella annularis
Up-close the polyps/coralites of the Orbicella genus look a bit like small volcanos.
This species forms "islands" of colonies, rather than a continuous sheet.
