This beak is most often used for drilling into and prying open their favorite bivalves, cowries and other shelled foods. [4] He described the derivation of the term as follows: The second head (Sematic Colours) includes Warning Colours and Recognition Markings: the former warn an enemy off, and are therefore called Aposematic [Greek, apo, from, and sema, sign][53], Aposematism is paradoxical in evolutionary terms, as it makes individuals conspicuous to predators, so they may be killed and the trait eliminated before predators learn to avoid it. All of these results contradict the idea that novel, brightly coloured individuals would be more likely to be eaten or attacked by predators. [69] Well-fed predators might also ignore aposematic morphs, preferring other prey species. [19], Once aposematic individuals reach a certain threshold population, for whatever reason, the predator learning process would be spread out over a larger number of individuals and therefore is less likely to wipe out the trait for warning coloration completely. Researchers have found that the poison is related to the toxicity of the Blue Ringed Octopus. Phototipps: 100mm or 60mm are both ok as the Flamboyant Cuttlefish is not shy – for photographing hunting scenes the 60mm is better though. [69] If so, predators would learn to associate the colour with unpalatability from males with the trait, while heterozygous females carry the trait until it becomes common and predators understand the signal. Photo by Silke Baron. Normally a brown color, this cuttlefish shifts to red, black and purple with golden spots when it becomes distressed, and the tips of its arms turn into a dark shade of red. Eggs can be also found troughout the season as they reproduce year round. A toxicology report has confirmed that the muscle tissue of flamboyant cuttlefish is highly toxic, making it only the third cephalopod found to be poisonous.

They like shallow waters and muddy or sandy substrates and sometimes reef-associated around the rubble zone and are spotted at Lembeh or Ambon dive sites. This adaptation has helped Metasepia pfefferi survive in the wild due to the small size of this species. [61] This suggests that Wallace's original view, that warning coloration helped to teach predators to avoid prey thus coloured, was correct. Spiny Devilfish inject their toxins thru their spines. The term was coined by Edward Bagnall Poulton[3][4] for Alfred Russel Wallace's concept of warning coloration. So what? [59][56][58][60] “Are the Flamboyant Cuttlefish in Lembeh Venomous or Poisonous? Best place to see Flamboyant Cutllefish in Lembeh Strait: Flamboyant Cuttlefish can be found on all Muckdive Sites in Lembeh. Cuttlefish have large, W-shaped pupils, eight arms, and two tentacles furnished with denticulated suckers, with which they secure their prey. They hunt for crabs, shrimp and small fish using tentacles with suckers to capture their prey. The easily detected warning is a primary defence mechanism, and the non-visible defences are secondary. This is the method of toxin transfer for all Scorpionfish, but also for Waspfish, Stonefish and Lionfish, which is exactly why we ask divers and photographers in Lembeh to be so aware of their immediate surroundings. Aposematism always involves advertising signals, which may take the form of conspicuous coloration, sounds, odours[2] or other perceivable characteristics. Aposematism is the advertising by an animal to potential predators that it is not worth attacking or eating. These are commonly asked critter-questions at Two Fish Lembeh, especially during weeks like these when all of the above mentioned animals are making a regular appearance. Pfeffers Flamboyant Cuttlefish While many cuttlefish have venomous bites, the flamboyant variety – Metasepia Pfefferi – is the only one to have deadly poisonous flesh. The toxin is similar to the one with which with which the blue ringed octopus kills with a bite. Take a look at even the strangest creatures in the world, such as the shape-shifting, poison-wielding, flashing-skinned flamboyant cuttlefish, and we can normally still relate to them in some way. If the species was already unpalatable, predators might learn to avoid the cluster, protecting gregarious individuals with the new aposematic trait. They use their camouflaging abilities to hunt down their prey. [25] Evolution of their conspicuous coloration is correlated to traits such as chemical defense, dietary specialization, acoustic diversification, and increased body mass. Concurrent reciprocal selection (CRS) may entail learning by predators or it may give rise to unlearned avoidances by them.
