Among hundreds of insect families, Hermatobatidae (commonly known as coral treaders) is one of the most unique. They are small, wingless predaceous bugs in the suborder Heteroptera. Adults are almost black in colour, measuring about 5 mm in body length and 3 mm in width.

RA was induced by administration of collagenase plus complete Freud's adjuvant in the knee joint region. The animals were treated with ozone therapy (1 ml O injection in the knee i.

Article Synopsis
- Naturalists have long studied animal coloration, but there's limited knowledge about embryonic colors, especially in water striders (Gerromorpha).
- By combining genetics and chemical analyses, researchers discovered that embryonic coloration arises from a biosynthesis pathway initially used for eye pigments, which was adapted for other body parts during development.
- Over time, different lineages of water striders have diversified their colors, with some evolving bright red while others lost color altogether, all while maintaining a stable biosynthesis pathway for 200 million years.
Cytogenetics analysis and testis morphology of aquatic species of the families Belostomatidae, Gelastocoridae, Gerridae, Notonectidae, and Veliidae (Heteroptera).

The Heteroptera have holocentric chromosomes with kinetic activity restricted to the end of chromosomes. The first meiotic division is reductional for the autosomes and equational for the sexual. Only a few species of this suborder have been analyzed.
