Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Europe: Mediterranean basin (including Mallorca, Sardinia), Atlantic basin south of English Channel and along western slope of British Isles; Rhine drainage. Hybrid zone with Gasterosteus aculeatus in English Channel, southern North Sea, Baltic Sea and their basins. Introduced to Switzerland (native in Basel). Invasive in upper Danube.

Short description Morphology | Morphometrics

Distinguished uniquely from congeners in Europe by the absence of scutes or lateral keel on caudal peduncle, except in few individuals from Sardinia. Differs further from congeners by the combination of the following characters: trunk lacking or with only 2-10 bony scutes; and scutes overlapping. Scutes may be more numerous and present on caudal peduncle in hybrid zone with Gaterosteus aculeatus (Ref. 59043).

Biology     Glossary (e.g. epibenthic)

Adults inhabit streams, lakes and ponds with slow to moderate current, clear water and sand bottom. In Mediterranean basin, commonly found in spring-fed water bodies and also occur in other habitats including brackish water. Feed predominantly on small invertebrates. Spawn in springs and brackish water. Males build, guard and aerate the nest where the eggs are deposited (Ref. 205). Locally rare or extirpated in several Mediterranean drainages. Size reaches up to about 10 cm SL (Ref. 59043).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Males defend territories where they construct a nest on the bottom in relatively shallow areas. They excavate to make a depression where they bring plant materials, which are glued together with kidney secretions and covered by sand, leaving only the entrance distinct. Females are led to the nest to spawn then chased away. Males guard and fan eggs which hatch in about 10 days. Juveniles are protected for a few days, after which males abandon the nest.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00410 - 0.02677), b=3.07 (2.85 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.2 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (15 of 100) .
