NATICA or the naticoici type holds a unique place in the ontogeny and phylogeny of the coiled Gastropoda. Its position in the history of the race has been admirably pointed out by Grabau1 in his " Studies of Gastropocla," and in his treatise on the "Phylogeny of Fusus and Its Allies. "9 There would be little cause at this time to take up the discussion

Subaerial hunting behaviour in Natica Gualteriana (naticid gastropod)
Palaeogeography, Palaeoclimatology, Palaeoecology, 1989Natica gualteriana, as observed on intertidal sand bars in Bantayan Island, Philippines, emerges from the sand at low tide when the bottom is exposed to the air, and hunts epifaunally for the trochacean gastropod Umbonium vestiarium. N. gualteriana captures U. vestiarium with a quick extension of the foot, triggered by direct contact with the prey. The

The excretion of110mAg by a gastropod species (Natica intricata)
Journal of Radioanalytical and Nuclear Chemistry, 1999The excretion kinetics of110mAg in a gastropod species contaminated through water pathway has been studied under laboratory condition. The pattern of the excretion results can be represented by a monophasic linear regression function. The excretion coefficient and biological half-life were calculated.

Tetrodotoxin secretion from the lined moon shell Natica Lineata in response to external stimulation
Toxicon, 1990The lined moon shell Natica lineata secretes tetrodotoxin (TTX) in response to an external stimulation such as removal from the seawater. The toxin released from the shellfish contained 14-361 mouse units of TTX per specimen. The shellfish did not secrete any further toxin when seawater removal was repeated over four times at about 1 hr intervals.

Occurrence of tetrodotoxin in the gastropod mollusk Natica lineata (lined moon shell)
Toxicon, 1990Paralytic toxicity was detected in 28 of 38 specimens of the gastropod mollusk Natica lineata (lined moon shell). The highest toxicity, expressed as tetrodotoxin (TTX), was 720 mouse units per gram (MU/g) muscle, followed by other parts which included salivary gland, brain and mouth organs (28 MU/g) and digestive gland (12 MU/g).

The effect of hunger on drilling behaviour of Natica tigrina: An experimental assessment
Palaeogeography, Palaeoclimatology, Palaeoecology, 2015article i nfo Drilling predation is one of the unique scenarios where past biotic interactions can be studied quantitatively and used to model behavioural evolution of the involved groups. Although it is recognized that hunger plays an im- portant role indetermining the behaviour of terrestrial predatory groups, its specifi ce ffect on ...

What controls cannibalism in drilling gastropods? A case study on Natica tigrina
Palaeogeography, Palaeoclimatology, Palaeoecology, 2014Abstract Cannibalism is observed among the drilling gastropods in Recent and in the fossil record. However, the ecological factors triggering cannibalism are not well understood. While competition over food is considered a factor to initiate cannibalism in certain groups, it is yet to be tested for drilling gastropods.
