Integral cryptanalysis on reduce-round SAILFISH-I

Cybersecurity
SAILFISH-I, first proposed by Agarwal et al. in 2022, is a lightweight block cipher with a typical Feistel structure, which is evaluated for the first time in this paper for its resistance to integral cryptanalysis.

Seascape Genomics and Phylogeography of the Sailfish (Istiophorus platypterus). [PDF]

Genome Biol Evol, 2023
AbstractPermeable phylogeographic barriers characterize the vast open ocean, boosting gene flow and counteracting population differentiation and speciation of widely distributed and migratory species. However, many widely distributed species consists of distinct populations throughout their distribution, evidencing that our understanding of how the ...

Genetically confirmed first records of an egg and a juvenile roundscale spearfish, Tetrapturus georgii. [PDF]

J Fish Biol
Abstract The roundscale spearfish (Tetrapturus georgii) is a poorly studied species with limited information available on its biology, ecology, and population status. Although the adult life stage of the species is morphologically distinguishable from closely related species such as the overexploited white marlin (Kajikia albida), misidentification is ...

Whale shark Rhincodon typus foraging on small schooling fish in the northern Mexican Caribbean. [PDF]

J Fish Biol
Abstract The whale shark (Rhincodon typus) aggregates in the Mexican Caribbean from May to September to feed on mixed zooplankton patches and fish spawn. For the first time in this area, we present evidence of observations of whale sharks feeding on schools of small fish, two in 2017 (10 individuals per flight) and one in 2024 (19 individuals).

Almost billfish: convergent longirostry, micro-dentition, and possible glandular sinuses in a large teleost fish from the Upper Cretaceous of Northern Italy. [PDF]

J Anat
A fossil rostrum fragment of a large teleost fish from the Upper Cretaceous of Northern Italy reveals remarkable anatomical convergences with Cenozoic and Recent billfishes (marlins, swordfishes, and akin). The extinct group Plethodidae independently acquired a long snout, micro‐teeth, and oil‐gland sinuses well before the evolution of true billfishes.

Sailfish generate foraging opportunities for seabirds in multi-species predator aggregations. [PDF]

Biol Lett
While various marine predators form associations, the most commonly studied are those between subsurface predators and seabirds, with gulls, shearwaters or terns frequently co-occurring with dolphins, billfish or tuna. However, the mechanisms underlying these associations remain poorly understood.
