ABOUT

Legless amphibians. Caecilians (said seh-SILL-yens) are tropical amphibians that appear to be large worms or slick snakes. They haven't any palms or legs, and on occasion it’s tough to tell which end is the head and that's the tail! Their vivid pores and skin is ringed with skin folds called annuli. Caecilians commonly are available in shades of grey, brown, black, orange, or yellow. some species have tiny, fishlike scales in the rings.

At home in dirt or water. most caecilians are burrowers, residing in a community of tunnels underground. A hard, thick, pointy skull helps these amphibians dig in soft dust. due to their underground way of life, caecilians have little want to look or listen. So, their eyes are tiny in a few species or hidden under the pores and skin or skull in different species, making simply grey bumps for eyes.

some South American species spend their lives in water in place of on land. Caecilians don’t have ear openings, so it is doubtful they are able to listen sounds the manner we do. Scientists have determined that an organ of their ear choices up vibrations from the ground to assist them locate predators and prey. Caecilians additionally use their sensitive tentacles. those are between the nostrils and the eyes and assist caecilians locate meals or their manner round.

HABITAT AND diet

The ebony-skinned caecilian looks as if a pass between an eel and an earthworm, however it's far an amphibian, like frogs and salamanders.

They get round. ranging from principal Africa, Southeast Asia, and southern Mexico to Argentina, these uncommon creatures decide on unfastened soil and leaf clutter in tropical forests or near rivers and streams.

Sharp inside the tooth. they'll appearance soft on the outside, however inner a caecilian’s mouth are dozens of needle-sharp teeth. The teeth can snatch worms, termites, beetle pupae, mollusks, small snakes, frogs, lizards, and even other caecilians! All food is swallowed complete. Caecilians have poisonous glands in their skin that now and again defend them from being eaten by way of other animals.
circle of relatives life

Oh, child! Like salamanders, caecilians produce young in two unique approaches, relying on the species. a few female caecilian species lay eggs in damp holes close to water. while the larvae hatch, they've gills and a short, finned tail to assist them swim in the water as they feed on plankton. via a series of changes, a single lung replaces their gills. Their pores and skin becomes thicker, the annuli develop, and sensory tentacles appear. At this point, the newly evolved grownup moves to the land and goes underground.
some species provide delivery to stay young that are completely advanced within the mother before they may be born.

nonetheless a thriller to me! imagine—there are over one hundred twenty species of those animals, a few as long as we're, that variety in the tens of millions on at the least 4 continents. And almost no one knows they’re there, not to mention ever sees one! That’s in all likelihood why almost not anything is thought of caecilians’ behavior and life-style. We nevertheless have much to find out about this uncommon amphibian!
on the ZOO

Worming their manner into our hearts. The San Diego Zoo received two ebony-skinned caecilians in 1993. They have been the first of any caecilian species in our series. We failed to recognise a lot about them, however keepers did a few studies and learned they regarded to like worms—loads! They every ate approximately 20 worms every week. but we couldn't discover a manner to display them to our guests, because the animals stay (and cover) in dust.
We currently do no longer have any caecilians in our series.

CONSERVATION

Habitat loss threatens many caecilian species. And they may be frequently pressured with snakes in a few areas and killed on the spot. The Basilan Island caecilian Ichthyophis glandulosus is endangered.

you may help us deliver species returned from the edge by using supporting the San Diego Zoo international wildlife Conservancy. together we are able to keep and guard flora and fauna around the world.
