[11][10]:25 Females are especially difficult to tell apart, as distinguishing features are mainly observed in the males at breeding season. They can adapt to a wide range of natural or semi-natural habitats, from forests over field edges to parks and gardens. Some newts living in the western United States are poisonous, perhaps thanks to bacteria living on their skin. 1. [16]:237 As in all salamanders, forelegs develop before the hindlegs. Males have an orange strip on the tail underside, and the throat and belly in males are orange to white with small dark, rounded spots (these are lighter with smaller spots in the female). Others, such as the calla lily, release a substance that burns and irritates a dog’s mouth and stomach, and symptoms can be mild to severe. [10]:121–129 They often share breeding sites with other amphibians, including other newts; in northern France, ponds with five newt species – smooth, palmate, alpine (Ichthyosaura alpestris), northern crested (Triturus cristatus) and marbled newt (T. marmoratus) – have been described. Mistletoe is also poisonous and Poinsettias can be extremely irritating to the mouth and stomach if ingested. Most people don’t know what hops are, but they are a type of plant that you can find in beer brewing. [16]:234–236, The aquatic larvae are 6.5–7 mm long and yellow-brown with two longitudinal stripes at hatching. Size and colour vary with environment, and the newts tend to be smaller in northern latitudes. Thanks for writing in, Most salamanders here in the states are not poisonous to dogs. The smooth newt is common over much of its range and classified as Least Concern species. [2][11] These authors, followed by Amphibian Species of the World,[3] recognise four former subspecies from southern Europe and west Asia as separate species, as they are morphologically and genetically distinct: the Greek smooth newt (L. graecus), Kosswig's smooth newt (L. kosswigi), the Caucasian smooth newt (L. lantzi) and Schmidtler's smooth newt (L. schmidtleri). This includes: Cleaning products, medicine, and batteries – all common household items that can cause big problems for your pets: Electrics in your home can turn into a hazard, especially if your pets are left home alone. Can you support us? [16]:238, Various pathogens and parasites have been found to infect smooth newts, including ranaviruses,[26] a picornavirus,[27], various protozoans,[10]:164 trematodes[28][10]:164 (of which Parastrigea robusta was found to cause the local decline of a population[29]) and at least 31 species of helminths. Ideal places to find them are rock crevices and logs though when breeding they prefer slow moving pools along costal streams. Between spring and summer, they breed in ponds or similar water bodies. It has been shown that females tend to mate preferentially with unrelated males, probably to avoid inbreeding depression. The dark spots grow larger, and the crest often has vertical dark and bright bands. [18]:26[16]:233–234, Subspecies differ slightly in male secondary characteristics: L. v. ampelensis has strongly developed toe flaps, its tail tapers into a fine thread (but not a distinct filament), and the body is slightly square in cross-section. [10]:196 Like all amphibians, it is also listed as protected species in the Berne Convention (Appendix III). Poinsettias are mildly toxic to dogs but the dangers are hardly ever serious or fatal. Originally described by Carl Linnaeus as a lizard, the smooth newt went by different genus names before the current classification in Lissotriton was adopted. 1. This winter, with millions being pushed into economic hardship, more beloved pets will urgently need our help. They can range from small puddles to larger ponds or shallow parts of lakes. : 238. Although the Carpathian newt is morphologically clearly different, hybridisation between the two species is frequent;[10]:26 it has been shown that smooth newt mitochondrial DNA has introgressed into and completely replaced that of the Carpathian newt populations. There you go, salamanders are poisonous. Generally, with some exceptions, newts spend more of their adult lives in the water than salamanders.

Poisonous to both cats and dogs, hyacinths belong to the Lilaceae family. vulgaris. [14][13][15] The palmate newt, although often occurring in the same habitats, almost never hybridises with the smooth newt. It is 1–1.5 mm high at mid-body, but higher along the tail. All the species within the genus Taricha possess tetrodotoxin, one of the most potent toxins known to science. [24], Migration to the breeding sites occurs as soon as February, but in the northern parts of the range and at higher altitudes, it may not start before summer. Read our vets' advice on keeping your pets safe when they're in the car. These fascinating animals are equipped with defense mechanisms deserving of much caution and fear.

[30], The smooth newt is common over much of its range. Water quality is less important; pH values from 4 to 9.6 are tolerated and in Germany, smooth newts have even been found in slightly brackish water. Although very rare, the rough-skinned newt is one of the most poisonous amphibians on the planet. [10]:78–80 It accepts a wide range of terrestrial and aquatic habitats.

Toxic plants can poison dogs if they eat or chew the parts of plant, bulb, flower or leaves. [16]:238–240, Paedomorphism, where adults stay aquatic and retain their gills and skin seams or only resorb them partially, occurs regularly but only in a small proportion of individuals. If ingested this may cause gastric upset and vomiting. The hindfeet have more or less developed toe flaps, depending on the subspecies. Within the smooth newt itself, genetic groups do not completely match the currently accepted subspecies (ampelensis, meridionalis, vulgaris), described based on morphology. He then guides her over the spermatophore so she picks it up with her cloaca. [25], Females lay 100–500 eggs, usually folding them into waterplants. Salamanders are poisonous and the way that they administer the poison is through secretion glands within its skin. The efts turn into mature adults at two to three years, and an overall age of 6–14 years can be reached in the wild. Founded in 1917 by animal welfare pioneer, Maria Dickin CBE, PDSA is the UK’s leading veterinary charity. The smooth newt was available in the Australian pet trade until 1997, when it was declared a "controlled pest animal" because of the risk of introduction. We have at least 8 frogs in there and at least 2 newts and I know the newts (and possibly some of the frogs, too) are endangered. Here are some of the most common poisonous plants, but there are others. [8]:233 They used the name Lissotriton, introduced by the English zoologist Thomas Bell in 1839 with the smooth newt as type species[9]:132 but then considered a synonym of Triturus. [16]:238 The newts recognise familiar territory using smell and visual cues, but could not orient themselves in experiments when they were transported far away from the home range. The five smooth newt species and the Carpathian newt (L. montadoni), which is their sister species, have collectively been referred to as the "smooth newt species complex". The tail also has a lower fin, and its end is pointed. [10]:29, Adult males of the smooth newt reach around 9–11 cm (3.5–4.3 in) head-to-tail length and are thus slightly larger than the females, which reach 8–9.5 cm (3.1–3.7 in). Outside the breeding season, both sexes are yellow-brown, brown or olive-brown. [1][16]:237 The IUCN, in 2008, assessed its threat status as Least Concern and found no general decline in populations. Many newt species have been found to produce this tetrodotoxin… The relationships within this species complex have however not been fully resolved.

Artifical hibernation sites ("newt hotels") were readily used in a study in Norway, especially by juveniles. [3], Molecular phylogenetic analyses have shown that the smooth newt is distinct from its four close relatives – the Caucasian, Greek, Kosswig's, and Schmidtler's smooth newt – which were formerly considered subspecies (see section Taxonomy above). meridionalis. The dry and velvety skin becomes smooth during the aquatic phase. [3] This genus however was found to be polyphyletic, containing several unrelated lineages,[5][6][7] and the small-bodied newts, including the smooth newt, were therefore split off as separate genus in 2004 by García-París and colleagues. Males court females with a ritualised underwater display. [10]:107, During the aquatic breeding season, males develop a skin seam or crest, which runs uninterrupted along the back and the tail.
