An adaptive explanation for the horse-like shape of seahorses [PDF]
The body shape of seahorses resembles the head and neck of horses because of their curved trunk, their ventrally bent head and their long snout. Seahorses evolved from ancestral, pipefish-like species, which have a straight body.

Feeding ecology of pipefish species inhabiting Mediterranean seagrasses
Pipefish are a vulnerable and diverse group of ichthyofauna tightly associated to seagrass meadows, key habitats in shallow marine areas. Despite of their charismatic role, main ecological features, habitat and diet of this group remain largely unknown. This study focuses on assessing pipefish habitat and feeding preferences including different hosting

We document novel interspecific associations of the endangered Atlantic chupare stingray (Styracura schmardae) in Caribbean sandy‐bottom habitats. Observations include nuclear–follower interactions with needlefish (Strongylura marina) and hitchhiking by sharksuckers (Echeneis naucrates), revealed through direct in situ records and citizen science data ...

Evolutionary ecology of pipefish brooding structures:embryo survival and growth do not improve with a pouch [PDF]
For animals that reproduce in water, many adaptations in life-history traits such as egg size, parental care, and behaviors that relate to embryo oxygenation are still poorly understood. In pipefishes, seahorses and seadragons, males care for the embryos

The evolutionary origins of Syngnathidae: pipefishes and seahorses
Despite their importance as evolutionary and ecological model systems, the phylogenetic relationships among gasterosteiforms remain poorly understood, complicating efforts to understand the evolutionary origins of the exceptional morphological and behavioural diversity of this group.

Male mate‐choice copying: a neglected aspect of sexual selection
Mate‐choice copying occurs when the choices of others influence an individual's mating preferences. While this behavior has been observed across various species, most research has focused on female copying behavior. However, male mate‐choice copying warrants independent attention due to the distinct benefits and costs it entails for males compared to ...

An evaluation of Northern Florida Bay as a nursery area for red drum, Sciaenops ocellatus, and other juvenile and small resident fishes. [PDF]
Red drum is one ofthe most popular species sought by anglers in Florida Bay, yet juveniles are rarely encountered. We evaluated Florida Bay as a nursery area for red drum by sampling for recently-settled late larvae in basin areas within the bay with an ...

Our study investigates inbreeding avoidance mechanisms at the gamete level in domesticated Atlantic salmon using sperm motility traits assessments, fertilisation trials, and paternity analysis under competitive conditions. We demonstrate that ovarian fluid from sibling females reduces sperm motility traits and fertilisation rates but found no ...

Extreme climate events such as heat waves are expected to increase in frequency under global change. As one indirect effect, they can alter magnitude and direction of species interactions, for example those between hosts and parasites.
