Planes on a Snake? On the Identities of Crab Larvae Rafting on Sea Snakes [PDF]
Ecology and Evolution, Volume 16, Issue 6, June 2026.We sequenced COI and 16S rRNA genes from 106 crab megalopae found rafting on the pelagic sea snake Hydrophis platurus to test whether they were the obligate rafting species Planes minutus. Instead, all larvae belonged to three inter‐ to supratidal grapsid crabs—Pachygrapsus socius, Goniopsis pulchra, and Grapsus grapsus—revealing no evidence of Planes.

Phylogenetic relationships of Grapsoidea and insights into the higher phylogeny of Brachyuran
Genomics, 2021 Decapoda is one of the most diverse crustacean orders, and has become an important research subject. However, the phylogenetic relationships among the main lineages of Decapoda remain uncertain, especially in the order Brachyura. Herein, we sequenced the whole mitochondrial genome of V.

Evidence of Cheliped Autotomy and Regeneration in the Lower Miocene Crab Achelous monspeliensis From Portugal [PDF]
Ecology and Evolution, Volume 16, Issue 7, July 2026.Crab autotomy with evidence of regeneration is described for the first time in the fossil record. Autotomy is a defensive behavior that affects more males than females of Achelous monspeliensis and may be related to mating season. ABSTRACT Autotomy—the voluntary shedding of a limb as a defensive response to predation, intraspecific aggression, or ...

Revealing the Diverse Allergenic Protein Repertoire of Six Widely Consumed Crab Species: A Species‐Specific Allergen in King Crab [PDF]
Allergy, Volume 81, Issue 5, Page 1500-1521, May 2026.This study comprehended the allergen profiles of six edible crab species using proteomic and transcriptomic analyses and identified 11 putative allergens. King crab has a distinct protein and allergen profile, with the discovery of malate dehydrogenase as a novel king crab‐specific allergen registered as Para c 11.

On Shell Closure and Beyond: Classification and Functional Interpretation of Chela Types in Paguroidea (Decapoda) [PDF]
Journal of Morphology, Volume 287, Issue 8, August 2026.MicroCT technology and 3D shape analysis were used to classify paguroid chelae into six distinct shape types: compact, sturdy, elongate, scutiform, discoid, and compact. Each type is linked to characteristic biological roles: paired semidiscoid chelae enable symmetrical shelter closure; scutiform and discoid chelae support one‐sided shelter closure ...
