Fish

Orange-spotted toadfish

Torquigener hypselogeneion

A small spotted fish that spends much of the day half buried in the sand. It is shy by nature, and no sighting is a promise.

Least ConcernIn 10 Atlas countries

Least Concern (IUCN, 2011) means it is not at high risk of extinction in its native range, but in the Mediterranean it is an invasive species.

Length

FishBase gives a maximum of 13 cm (5.1 in). A 2023 study of 1,360 fish in the Eastern Mediterranean estimated they grow towards about 17.4 cm (6.9 in), with maturity at about 10 cm (3.9 in).

Weight

An average adult female of 13 cm weighed about 45.7 g (1.6 oz) in that study.

Next to a person

About as long as a hand, and about as heavy as a large egg.

What it eats

A carnivore that forages on sandy bottoms for small animals, including snails (Cerithium scabridum), hermit crabs, other crustaceans and sea urchins. It eats less during the peak spawning season.

Around people

Look, do not touch

How it lives

Lives in small loose groups on shallow sand flats and in estuaries, recorded at about 1 to 22 m. By day it often sleeps buried under the sand with only its eyes showing. In the Mediterranean it lives about 4 years. Females lay many eggs: an average adult female held about 1,250 eggs per gram of body weight. It feeds through the day and can be curious about divers.

Where it goes

A small bottom dweller that lives in loose groups on sandy flats. The sources I opened give no migration data. By day it often buries itself in the sand with only its eyes showing.

We only draw a journey on the map when scientists have tracked it or clearly documented it. For this animal we have not found one yet.

Populations

Native to the Indian and western Pacific oceans, from East and South Africa east to Samoa and north to southern Japan, and rated Least Concern by the IUCN (2011) within its native range. In the Eastern Mediterranean it is an invasive species. A 2023 study treats the fish known there as Torquigener flavimaculosus as the same species and sampled it at Finike and Fethiye in Turkey and in Cyprus. The authors recommend listing it as a priority invasive species to monitor. No population count is given.

Meet it respectfully

Look, but do not touch. A 2023 review warns that this fish can look harmless and become used to people, yet it bites if handled, and it can get excited around fresh food. Never feed, bait, handle or chase it, and never eat it. Keep your hands off the sand where one may be buried. I did not read local rules for Turkish waters, so follow your guide.

Fun fact

Tap the bulb to light it up.
