Biology Urothods are long and live on the sea bed or in shallow burrows in gravelly substrates or muddy sand. They can swim for short distances. They are vulnerable to dredging but are able to recover afterwards and re-establish their burrows. They are detritivore, deposit feeders and also selectively scrape microorganisms from grains of sand. Reproduction ''Urothoe'' reaches sexual maturity at five months and may live for about a year. The sexes are distinct and breeding takes place in the summer months. Fertilisation is internal fertilisation, internal and there are about fifteen egg (biology), eggs per brood, produced in a cycle of about fifteen days. Fecundity is high and the juvenile (organism), juveniles grow fast but biological dispersal is very limited. Species ''Urothoe'' contains the following species: *''Ur ...
